Jeremias Maerki 44c5761c1a Merged branch https://svn.apache.org/repos/asf/xmlgraphics/fop/branches/Temp_ImagePackageRedesign (revs 594558 to 611138) into Trunk: A new image loading framework has been introduced to fix various problems with external graphics and improve performance. Switched to Batik 1.7. Added xml-apis-ext.jar as needed by Batik 1.7. Updated to latest XML Graphics Commons snapshot. Changelog of branch: ------------------------------------------------------------------------ r594558 \| jeremias \| 2007-11-13 16:04:56 +0100 (Di, 13 Nov 2007) \| 1 line Branch for image package redesign ------------------------------------------------------------------------ r594560 \| jeremias \| 2007-11-13 16:10:35 +0100 (Di, 13 Nov 2007) \| 1 line Implementation of Dijkstra's algorithm for finding the shortest path. Used in the new image package to find the best combination of image loaders and image converters to provide an image in the optimal form for a renderer. ------------------------------------------------------------------------ r594848 \| jeremias \| 2007-11-14 13:12:50 +0100 (Mi, 14 Nov 2007) \| 3 lines Initial upload of what I have already for the image package redesign. For now, it's in a parallel package (image2). The final package name is TBD. The code isn't hooked into the renderers, yet, and there's no image cache. This is still all work in progress. ------------------------------------------------------------------------ r594851 \| jeremias \| 2007-11-14 13:20:12 +0100 (Mi, 14 Nov 2007) \| 1 line Test cases and additional test files for the new image package. ------------------------------------------------------------------------ r595305 \| jeremias \| 2007-11-15 15:01:37 +0100 (Do, 15 Nov 2007) \| 1 line Small mistake while reimplementing JPEG. ------------------------------------------------------------------------ r595308 \| jeremias \| 2007-11-15 15:13:36 +0100 (Do, 15 Nov 2007) \| 5 lines Introduced a usage penalty for ImageLoaders so we can calculate an overall penalty for a pipeline. Multiple image flavors can be passed to ImageManager.getImage() if the caller supports multiple formats. The image package chooses the best pipeline. Implemented a converter from RenderedImage to PNG. Implemented loaders for raw formats (EMF, JPEG and PNG). Hooked the new image package into the RTF handler as first real proof-of-concept. ------------------------------------------------------------------------ r596240 \| jeremias \| 2007-11-19 11:02:13 +0100 (Mo, 19 Nov 2007) \| 1 line Fixed bug in pipeline selection. ------------------------------------------------------------------------ r596242 \| jeremias \| 2007-11-19 11:03:06 +0100 (Mo, 19 Nov 2007) \| 1 line MIME type in parentheses behind the URI makes more sense. ------------------------------------------------------------------------ r599430 \| jeremias \| 2007-11-29 14:08:01 +0100 (Do, 29 Nov 2007) \| 1 line Support for baseline information (needed by at least MathML). ------------------------------------------------------------------------ r599433 \| jeremias \| 2007-11-29 14:09:04 +0100 (Do, 29 Nov 2007) \| 1 line Bugfix: BMP don't all have resolution information. ------------------------------------------------------------------------ r599434 \| jeremias \| 2007-11-29 14:10:54 +0100 (Do, 29 Nov 2007) \| 1 line Change MIME type ------------------------------------------------------------------------ r599436 \| jeremias \| 2007-11-29 14:17:14 +0100 (Do, 29 Nov 2007) \| 3 lines Started integrating into Java2D and PostScript renderers and ExternalGraphic. Added support for EPS graphics. Added support for raw embedding of JPEG images (for PostScript). ------------------------------------------------------------------------ r600821 \| jeremias \| 2007-12-04 08:51:06 +0100 (Di, 04 Dez 2007) \| 5 lines Clean up Javadocs Generally make more useful. Reuse FOProcessor instance for the whole run to actually feel the effect of an image cache attached to the FopFactory. Add option to prompt the user before actually starting (in order to connect a VM monitor). ------------------------------------------------------------------------ r600870 \| jeremias \| 2007-12-04 11:27:51 +0100 (Di, 04 Dez 2007) \| 14 lines Note: The API of the new image package has changed a bit. (it became necessary when I introduced caching) The direct dependency on FOUserAgent has been removed to make the image package more universally usable. Instead an ImageContext (provided by FopFactory in FOP) and ImageSessionContext (provided by FOUserAgent in FOP) was introduced. Introduced image caching with soft references (I didn't reintroduce the FOUserAgent lock, yet, because it doesn't help much) ImageInfo doesn't carry the Source for the image anymore. The Source is provided by the new ImageSessionContext.java and only shared within the same thread to make things simpler and to avoid complex synchronization and cleanup. Image instances now indicate whether they are cacheable (not all Image instances are cacheable, for example when they just carry an InputStream). Moved the converter pipeline functionality into its own subpackage to keep "spi" clean. Added checks in ImageSize to detect incomplete Preloaders. ImageSource can now indicate whether its a fast source (loading from local file) or a slow source (loading over the network). (but this isn't used, yet) Fixed a bug in WMF and SVG preloaders: they didn't close their Sources after fully loading the images. Bugfix in ImageRawJPEG: it illegally reported being an EPS file ImageRawStream got an "InputStreamFactory" so it is possible to reuse raw images if they have been loaded into memory (or to a local file which hasn't been implemented, yet). The pipeline code now converts single-use raw images to reusable raw images when possible. But there's nothing built in to restrict the image size to a maximum, yet. Improved JPEG preloader so it can stop early an deal with images that have to APP0 segment. Images from digicams are such an example. They carry the resolution info in the EXIF block which is currently not interpreted. Fallback is to the configured source resolution. ------------------------------------------------------------------------ r600930 \| jeremias \| 2007-12-04 14:25:43 +0100 (Di, 04 Dez 2007) \| 1 line Package HTML Files. ------------------------------------------------------------------------ r600934 \| jeremias \| 2007-12-04 14:34:41 +0100 (Di, 04 Dez 2007) \| 1 line Javadoc fixes ------------------------------------------------------------------------ r602023 \| jeremias \| 2007-12-07 09:46:56 +0100 (Fr, 07 Dez 2007) \| 2 lines Bugfix for bug in SVG preloader which didn't calculate the size of an SVG correctly when there's no explicit size. ------------------------------------------------------------------------ r602024 \| jeremias \| 2007-12-07 09:49:49 +0100 (Fr, 07 Dez 2007) \| 1 line Some small javadoc and logging improvements/refinements. ------------------------------------------------------------------------ r602025 \| jeremias \| 2007-12-07 09:50:22 +0100 (Fr, 07 Dez 2007) \| 1 line Enable assert keyword for javadoc production. ------------------------------------------------------------------------ r602032 \| jeremias \| 2007-12-07 09:59:10 +0100 (Fr, 07 Dez 2007) \| 11 lines Added color space information and an optional ICC color profile to the basic Image interface. Reimplemented transparency support (for now only for ImageIO loader and PDF output) ImageIO preloader passes the already loaded metadata to the ImageIO loader through the "custom objects" so it doesn't have to load them again. PDF library: Corrected the naming of the method indicating the "bits per component" (bits per component != bits per pixel) PDF library: Added a method which lets a user override values in an XObject's dictionary after the major values have been set (useful not to make the PDFImage interface more complicated). PDF library: Support for gray transparent colors. PDF library: Added a convenience class for alpha channel bitmaps (AlphaRasterImage) Integration of the new image package into the PDFRenderer (currently supports all previous embedding methods except deprecated EPS embedding and CCITT embedding, now supports even more transparency options than before) ------------------------------------------------------------------------ r602033 \| jeremias \| 2007-12-07 09:59:57 +0100 (Fr, 07 Dez 2007) \| 1 line Small optimization from my failed experiments to support native PNG embedding. ------------------------------------------------------------------------ r602034 \| jeremias \| 2007-12-07 10:01:34 +0100 (Fr, 07 Dez 2007) \| 1 line Don't use "content" filter for ICC profiles. Instead compress using "default". "content" is for page content. ------------------------------------------------------------------------ r602036 \| jeremias \| 2007-12-07 10:02:25 +0100 (Fr, 07 Dez 2007) \| 1 line Added general key for precompressed content of any kind. ------------------------------------------------------------------------ r602037 \| jeremias \| 2007-12-07 10:03:39 +0100 (Fr, 07 Dez 2007) \| 1 line Various variants of the FOP logo for testing. Some of them have transparency info. ------------------------------------------------------------------------ r602228 \| jeremias \| 2007-12-07 22:30:17 +0100 (Fr, 07 Dez 2007) \| 4 lines Discarded PreloaderPNG in favor of PreloaderImageIO which now supports all formats supported by ImageIO (meaning that you can uses JPEG-2000 images if you have a suitable ImageIO codec installed). ImagePreloader.getMimeType() removed because it isn't really used in the new setup. ImagePreloader.getPriority() introduced which allows to prioritize preloaders and thus gives the opportunity to tweak the order in which the preloaders are checked when an image is inspected. ImageLoaderImageIO can now use multiple Readers if one fails (one codec may not support all format variants, for example). ------------------------------------------------------------------------ r602229 \| jeremias \| 2007-12-07 22:30:48 +0100 (Fr, 07 Dez 2007) \| 1 line Added a toString() impl for debugging. ------------------------------------------------------------------------ r602442 \| jeremias \| 2007-12-08 11:36:32 +0100 (Sa, 08 Dez 2007) \| 6 lines Support handling images with no associated URI (from instream-foreign-object). These images are not cached. Add support for plain image conversion (i.e. with no loading) for instream-foreign-object. Add convenience writeTo() methods in ImageRawStream to save a few lines of code. Support for instream-foreign-object in RTF output. Teach RTF library to handle images without an associated URL. ------------------------------------------------------------------------ r603191 \| jeremias \| 2007-12-11 11:03:32 +0100 (Di, 11 Dez 2007) \| 2 lines Bugfix: Graphics2DAdapter didn't do the graphics state save correct so subsequent images may have been painted with the wrong transformation matrix. Bugfix: bitmap images didn't scale correctly when the resolutions were changed. ------------------------------------------------------------------------ r603207 \| jeremias \| 2007-12-11 12:08:36 +0100 (Di, 11 Dez 2007) \| 1 line Convenience method for obtaining the image size in points. ------------------------------------------------------------------------ r603208 \| jeremias \| 2007-12-11 12:12:50 +0100 (Di, 11 Dez 2007) \| 3 lines Precisely define the expectations for the area parameter in Graphics2DImagePainter. New ImageConverter: Bitmap -> Graphics2D ------------------------------------------------------------------------ r603209 \| jeremias \| 2007-12-11 12:15:49 +0100 (Di, 11 Dez 2007) \| 3 lines Refine pipeline building: Expose a method to allow the PS Renderer to predict what kind of pipeline will be selected (because it doesn't support all image types as PostScript forms) If there are multiple candidate pipelines for one conversion type, choose the one with the lowest penalty, not just the one that happens to be first. ------------------------------------------------------------------------ r603250 \| jeremias \| 2007-12-11 15:17:32 +0100 (Di, 11 Dez 2007) \| 1 line Removing failed experiment: raw PNG embedding didn't work out. ------------------------------------------------------------------------ r603254 \| jeremias \| 2007-12-11 15:29:48 +0100 (Di, 11 Dez 2007) \| 2 lines Plugged new image package into form generation for PostScript. XML images and EPS files are currently supported as forms. They are added inline. ------------------------------------------------------------------------ r603256 \| jeremias \| 2007-12-11 15:34:52 +0100 (Di, 11 Dez 2007) \| 1 line Embedding EPS in PDF is no longer implemented as it is a deprecated feature in PDF. Therefore, this test is not needed anymore. The PDF renderer will say: "Cannot load image (no suitable loader/converter combination available) for myfile.eps (application/postscript)" ------------------------------------------------------------------------ r603266 \| jeremias \| 2007-12-11 16:16:22 +0100 (Di, 11 Dez 2007) \| 1 line Size calculation for images can be slightly different after the redesign due to different rounding. Give a little tolerance. ------------------------------------------------------------------------ r603271 \| jeremias \| 2007-12-11 16:24:08 +0100 (Di, 11 Dez 2007) \| 1 line Bugfix: Only generate the FixedLength if there is baseline information. ------------------------------------------------------------------------ r603358 \| jeremias \| 2007-12-11 22:13:22 +0100 (Di, 11 Dez 2007) \| 1 line Switched background images to new image package. ------------------------------------------------------------------------ r603632 \| jeremias \| 2007-12-12 15:52:09 +0100 (Mi, 12 Dez 2007) \| 1 line Switch to new image package for PDF/SVG support. ------------------------------------------------------------------------ r603642 \| jeremias \| 2007-12-12 16:30:16 +0100 (Mi, 12 Dez 2007) \| 3 lines Initialized merge tracking via "svnmerge" with revisions "1-594557" from https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk ------------------------------------------------------------------------ r603656 \| jeremias \| 2007-12-12 17:13:06 +0100 (Mi, 12 Dez 2007) \| 307 lines Merged revisions 594558-603642 via svnmerge from https://svn.apache.org/repos/asf/xmlgraphics/fop/trunk ........ r594571 \| vhennebert \| 2007-11-13 17:24:32 +0100 (Di, 13 Nov 2007) \| 7 lines Moved the creation of grid units to the FO tree building stage. Brought a few improvements along with the move: - bugfix: border-resolution for border-end on row-spanning cells was wrong - bugfix: in case of missing cells the border-end of the table was applied to an inner cell, instead of the cell in the last column (but missing cells aren't painted yet :-\) - bugfix: in collapsing-border model, border-before and -after specified on table-column were applied to every cell of the column, instead of only the first and the last ones - border resolution is now made progressively when possible, and no longer triggers the fetching of all the rows of the table Added testcases for the border conflict resolution (between the various elements of a table and not only the cells) ........ r594578 \| vhennebert \| 2007-11-13 17:50:09 +0100 (Di, 13 Nov 2007) \| 2 lines Moved GridUnit from layoutmgr/table to fo/flow/table ........ r594579 \| vhennebert \| 2007-11-13 17:55:54 +0100 (Di, 13 Nov 2007) \| 2 lines Changed back visibility of fields from public to package-private, due to the move of GridUnit in the fo.flow.table package ........ r594584 \| vhennebert \| 2007-11-13 18:13:19 +0100 (Di, 13 Nov 2007) \| 2 lines Use a singleton for a default BorderInfo of style none, instead of every time a new instance ........ r594592 \| vhennebert \| 2007-11-13 18:39:17 +0100 (Di, 13 Nov 2007) \| 2 lines Cleaned up RowGroupLayoutManager and TableRowIterator ........ r594821 \| vhennebert \| 2007-11-14 11:18:45 +0100 (Mi, 14 Nov 2007) \| 2 lines Moved EffRow to the fo.flow.table package ........ r594829 \| vhennebert \| 2007-11-14 11:41:52 +0100 (Mi, 14 Nov 2007) \| 2 lines Reduced visibility of some methods and constructors from public to package-private, as a consequence of the move of GridUnit to the fo.flow.table package ........ r594836 \| vhennebert \| 2007-11-14 12:14:03 +0100 (Mi, 14 Nov 2007) \| 2 lines Restored the setting of the parent table-row element on grid units ........ r594852 \| vhennebert \| 2007-11-14 13:21:53 +0100 (Mi, 14 Nov 2007) \| 2 lines Restored the setting of rowIndex on primary grid units (although testcases were already working...) ........ r595297 \| jeremias \| 2007-11-15 14:28:58 +0100 (Do, 15 Nov 2007) \| 2 lines Bugzilla #43143: Had to remove the Expert(Subset) Encoding detection as this caused problems with a barcode font that used dfCharset=2 but was not using ExpertSubset encoding.

The exception was a follow-up exception after a PDFConformanceException that was swallowed by a default ErrorListener. ........ r600521 \| jeremias \| 2007-12-03 14:21:06 +0100 (Mo, 03 Dez 2007) \| 1 line Added a possibility to rerun the whole run a defined number of times to test for possible issues outside a single rendering run. ........ r600529 \| jeremias \| 2007-12-03 14:32:04 +0100 (Mo, 03 Dez 2007) \| 1 line Oops. ........ r601413 \| vhennebert \| 2007-12-05 17:56:47 +0100 (Mi, 05 Dez 2007) \| 2 lines Typo in property: svn:kewords -> svn:keywords ........ r601415 \| acumiskey \| 2007-12-05 18:11:44 +0100 (Mi, 05 Dez 2007) \| 2 lines Corrected javadocs ........ r601416 \| acumiskey \| 2007-12-05 18:12:54 +0100 (Mi, 05 Dez 2007) \| 2 lines Corrected javadoc ........ r601417 \| acumiskey \| 2007-12-05 18:13:31 +0100 (Mi, 05 Dez 2007) \| 2 lines Corrected javadoc ........ r601419 \| acumiskey \| 2007-12-05 18:15:46 +0100 (Mi, 05 Dez 2007) \| 2 lines Improved use of logging ........ r601423 \| acumiskey \| 2007-12-05 18:19:43 +0100 (Mi, 05 Dez 2007) \| 2 lines Corrected javadoc, fixed checkstyle issues, and now also correctly caters for negative number conversions ........ r601424 \| acumiskey \| 2007-12-05 18:21:15 +0100 (Mi, 05 Dez 2007) \| 2 lines Fixed checkstyle issues ........ r601426 \| acumiskey \| 2007-12-05 18:24:15 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601427 \| acumiskey \| 2007-12-05 18:25:07 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601428 \| acumiskey \| 2007-12-05 18:25:58 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601429 \| acumiskey \| 2007-12-05 18:27:06 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601430 \| acumiskey \| 2007-12-05 18:28:03 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601431 \| acumiskey \| 2007-12-05 18:28:48 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601432 \| acumiskey \| 2007-12-05 18:29:31 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601433 \| acumiskey \| 2007-12-05 18:30:04 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601434 \| acumiskey \| 2007-12-05 18:31:20 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601435 \| acumiskey \| 2007-12-05 18:32:29 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601436 \| acumiskey \| 2007-12-05 18:34:44 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601437 \| acumiskey \| 2007-12-05 18:35:31 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601438 \| acumiskey \| 2007-12-05 18:36:12 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes and cleanup ........ r601439 \| acumiskey \| 2007-12-05 18:37:40 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601440 \| acumiskey \| 2007-12-05 18:39:54 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601442 \| acumiskey \| 2007-12-05 18:42:13 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601443 \| acumiskey \| 2007-12-05 18:42:48 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601444 \| acumiskey \| 2007-12-05 18:43:46 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601445 \| acumiskey \| 2007-12-05 18:44:36 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601446 \| acumiskey \| 2007-12-05 18:45:20 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601447 \| acumiskey \| 2007-12-05 18:47:44 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601448 \| acumiskey \| 2007-12-05 18:48:56 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601449 \| acumiskey \| 2007-12-05 18:49:46 +0100 (Mi, 05 Dez 2007) \| 2 lines Checkstyle fixes ........ r601712 \| acumiskey \| 2007-12-06 12:57:14 +0100 (Do, 06 Dez 2007) \| 2 lines Temporary fix to the build ........ r602045 \| jeremias \| 2007-12-07 10:20:28 +0100 (Fr, 07 Dez 2007) \| 1 line Avoid a NPE in toString(). ........ r602125 \| maxberger \| 2007-12-07 16:36:53 +0100 (Fr, 07 Dez 2007) \| 6 lines Updated xmlgraphics from SVN Added autodetection of fonts in jar files (x-font and x-font-truetype) Added files needed for testcase Please note: Actual testcase is still missing!
