GRX problems and things that must to be done
by Mariano Alvarez Fernandez 06 Aug '01

06 Aug '01

This is a doc I plan to add to the GRX web site, it is a list of problems or things that are not problems, but must to be done (I'm not sure if it is well expresed), please make commnets (or better pick one :-) ------------------- GRX problems and things that must to be done Linux console framebuffer driver: Try to change modes if the underlaying framebuffer driver allow it. Hide the text cursor. Working mouse (this is not trivial), GRX linux console mouse is handled by svgalib functions, but obviously this not work with the framebuffer driver, a new mouse driver is necesary, but Linux don't have a real mouse driver, and the user program must handle all the possible mouse types. Win32 drivers: There is a general design problem. The video driver is initiated at the begining instead when the user program call GrSetDriver (usually indirectly by calling GrSetMode), this makes difficult the use the memory driver. Logical operations for 8 bpp are wrong implemented, they must operate with color indices instead of colors. Drawline must paint the last point (not trivial). Support for all logical operations in drawpixel, drawblock and putscanline. Implement getiscanline for 8 and 24 bpp. Implement bltv2r for 24 bpp. Implement full screen mode when maximum resolution is required. X11 driver: Investigate why bccbgi test program doesn't restart when it switchs to text mode. Try to make GrPixel faster. The driver can't respond to PAINT events, so it has problems with XFree86 v4 because the backing-store is not enabled by default. The best solution is to have a context to save the actual window (and the GrPixel problem can be solved too). Te workaround is to add the next lines to the /etc/X11/XF86Config-4 file, in the Device section: Option "BackingStore" Option "SaveUnders" SVGALIB driver: The default mouse aceleration is too fast. VGA DOS driver: It can be improved a lot, replacing the generic funtions it uses.

GRX 2.4.3
by Mariano Alvarez Fernandez 06 Aug '01

06 Aug '01

Hi, all. First I expect the list will be working. I want to announce GRX 2.4.3 Changelog: 01/06/27 Added new targets to makefiles: install-bin, uninstall-bin, install-fonts and uninstall-fonts (readme file updated) 01/06/26 Moved bin2c, fnt2c, vesainfo, lfbinfo and modetest to src/utilprog. They are build in the source makefile. 01/06/22 Except for the w32 version the install target installs the info manual. As suggested by Maurice Lombardi and Waldemar Schultz 01/06/21 pngtest test program added. It works too without png support and shows a message 01/06/20 Changed BCCGRX cleardevice function to clear the screen to the current BACKGROUND color instead of black. Suggested by Waldemar Schultz 01/06/19 ctx2png functions (GrSaveContextToPng, GrLoadContextFromPng, GrQueryPng, GrPngSupport) integrated in GRX. src/pnm subdir renamed to src/gformats. Added dummy functions if there isn't png support 01/06/18 New API functions: GrLoadContextFromPnmBuffer and GrQueryPnmBuffer Because I have problems uploading big files to my ISP I can't provide urls to download the new version at the moment. I had uploaded the zip version to delorie server, so expect it will be on simtel in a couple of days. Greetings, M.Alvarez
