* | Optimise the RGB to pixel conversion to simple shiftsPierre Ossman2014-07-073-51/+65
| | | | | | | | | | Might as well make it inline at this point as well as it is used heavily in other routines that convert entire blocks of pixels.
* | Remove magic JPEG variables from ConnParamsPierre Ossman2014-07-073-14/+3
| | | | | | | | | | | | Custom compression level and JPEG on/off are not inherent parts of the protocol negotiation so they do not belong in ConnParams. Let the UI frontend handle such things instead.
* | Clean up the encoding parser in ConnParamsPierre Ossman2014-07-071-48/+55
| |
* | Make the subsampling setting follow the common stylePierre Ossman2014-07-078-45/+64
| |
* | Stop storing a copy of the encodings as we don't use it for anythingPierre Ossman2014-07-072-14/+3
| |
* | Get rid of the register mechanism for encoders and decodersPierre Ossman2014-07-0725-183/+77
| | | | | | | | We have no use for it, so let's keep things simple.
* | Be more consistent in referring to pixel byte streams as buffersPierre Ossman2014-07-078-29/+29

* | Document the different pixel representations that we deal withPierre Ossman2014-07-071-1/+10
| |
* | Get rid of unused things in the ZRLE encoderPierre Ossman2014-07-073-35/+13
| | | | | | | | | | Get rid of unused shared MemOutStream and variable max length functionality in the ZRLE encoder.
* | Remove the scaled pixel buffer classes as they are not used.Pierre Ossman2014-07-073-354/+0
| | | | | | | | | | There were also reports of them being broken last time we still made use of them.
* | Remove unused (and commented out) PixelBuffer::getPixel()Pierre Ossman2014-07-072-17/+0

* | Support keeping libjpeg's default compression settingPierre Ossman2014-07-071-3/+8
| |
* | Converting to RGB might involve a precision increasePierre Ossman2014-07-073-15/+59
| | | | | | | | | | | | | | Need to do more than a simple shift to get the appropriate new value. This isn't quite as exact as a proper multiplication and division, but the error is so small it's not worth the extra cycles.

* The ZRLE decoder relied on an assert() for boundary checks. A defaultPierre Ossman2014-03-191-3/+10
| | | | | | | | | | Release build however will remove all asserts making it possible to overrun this buffer. This could be exploited by a malicious server. This issue has been assigned CVE-2014-0011. Patch by Tim Waugh for Red Hat. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@5167 3789f03b-4d11-0410-bbf8-ca57d06f2519
* Make sure the fill function pointer gets updated if thePierre Ossman2014-01-072-5/+24

Fixes a crash with the mouse pointer in WinVNC. Based on work done by Daniel Wyatt (dewyatt). git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@5152 3789f03b-4d11-0410-bbf8-ca57d06f2519

* We were not handling the "sync next" fence properly as we sent the responsePierre Ossman2012-07-202-6/+10
| | | | | | | | | right after we got the request (instead of waiting for the next command). This created a race where we could lose pixel format sync between the client and the server. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4943 3789f03b-4d11-0410-bbf8-ca57d06f2519

* Fix regression caused by r4841. That patch assumed that JPEG encoding ↵DRC2012-02-133-45/+47

Reorganise and clean up the code to handle this, and make the raw frame buffer pointer const so that we might avoid such bugs in the future. git-svn-id: svn://svn.code.sf.net/p/tigervnc/code/trunk@4841 3789f03b-4d11-0410-bbf8-ca57d06f2519

* Increase the default compression level to cater to a broader range of usersPierre Ossman2011-11-202-2/+3
