2012-02-02Add 4 new raster decompression methods to PCL.Henry Stiles1-2/+3
HPGL/2 and RTL plotters support the following decompression methods: uncompressed block (#4), CCITT group 3 1 dimensional (#6), CCITT group 3 2 dimensional (#7), CCITT group 4 2 dimensional (#8). These have gotten little testing we only have a couple test files at the current time.

logical page is not seen in the HPGL-2/RTL examples we have. There might be something more complicated going on here, it would be difficult to determine without a device to run experiments.

by 1 device pixel. We now emulate this behavior and correctly print the test files in the bug at 600 dpi. Many regression files will shift by one pixel with this change. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11898 a1074d23-0009-0410-80fe-cf8c14f379e6

2009-09-28The last change to rtgmode.c, revision 10098, was incorrect. TheHenry Stiles1-1/+2

2007-09-25Replace the 'private' define with the now standard C keyword 'static'.Ralph Giles1-14/+14
The compilers we support have supported static for some time now, so it makes sense to use it by default. This also makes the code less idiomatic, and removes one of the obstacles to compiling Ghostscript as C++. The patch also removes support for compilation with -dNOPRIVATE, which is not longer necessary with modern debuggers. git-svn-id: http://svn.ghostscript.com/ghostpcl/trunk/ghostpcl@2923 06663e23-700e-0410-b217-a244a6096597

2006-09-07Merge the gs853merge branch down into the trunk. This ports ghostpcl andRalph Giles1-4/+4
ghostxps to build against a branch of ghostscript close it its current mainline (around r7000) between Ghostscript 8.54 and 8.55. This mostly consists of removing the memory pointers from many calls as well as a few other api changes, as well as some makefile updates, which were skewed between the branches. Nevertheless this is a big merge and there are likely to be a few mistakes. The previous trunk is tagged as /tags/ghostpcl-pre855merge for comparision. Both pcl6 and pspcl6 build and run with the Artifex font scaler (the native gs one). pcl6 compiles but does not link with ufst. pspcl6 does not compile with ufst, but that's not too different from what was happening in the branch. Fixing this will of course come next. git-svn-id: http://svn.ghostscript.com/ghostpcl/trunk/ghostpcl@2566 06663e23-700e-0410-b217-a244a6096597
2006-08-23Raster resolution without parameters defaults to 75dpi.Stefan Kemper1-1/+2
Raster height > raster sent and source transparency has a optimized path for drawing a white rectangle to "complete" the missing raster. There is still a bug where the right color is black or pen 0 has color and the rectangle should be color instead of white.

rtgmode.c: The unusual behavior that does not allow raster scaling if the palette is fixed (not writable) only applies to implicit raster entry on the HP Color Laserjet 4600.

1999-10-25Raster state's graphics margin was not being reset when a pcl resetHenry Stiles1-0/+1
was issued, potentially resulting in an obscure bug. If the margin was set in raster mode and raster mode is subsequently entered implicitly, after a reset, the graphics margin was improperly retained. Running the fts test panels 2278-83 immediately followed by fts panel 2290 improperly retains the graphics margin which resulting indirectly in a misplaced vertical line. The probability of this occurring in any real pcl file is very low. git-svn-id: http://svn.ghostscript.com/ghostpcl/trunk/ghostpcl@1001 06663e23-700e-0410-b217-a244a6096597

particular transformation in effect, the initial horizontal position of 7008 centi-points would come back as 7007.9994... centi-points, which was converted to 7007 centipoints, which would come back as 7006.9994... centi-points, and so on. The process finally stopped at about 6600 centi-points, due to a change in the least significant bit of the tx field of transformation matrix.
