Announce: GRX 2.3.3
by Mariano Alvarez Fernandez 01 Feb '01

01 Feb '01

Hi! I have pakaged a new GRX release, these are the changes: - Applied the last patch from Andris Pavenis. - Added the updated GRX user's guide. - BGI test programs moved to test/bgi. - bgi fonts removed, sorry. - And the big one. Modified the head sources (BCC2GRX included) to point to copying.grx instead doc/copying.cb. Note that the license has not changed. The modification is only to clarify it and to integrate BCC2GRX . Testing. I have tested the library on DJGPPv2, linux svgalib and linux X11. The bgidemo doesn't work on X11. People who can test other plattforms are welcome. Future plans. I will wait a month or so. If no GRX authors disagree with the big change I will release 2.3.4 with some changes on the test programs and adding my ctx2pnm routines (and any other changes people can submit). I want 2.3.4 to be the next official GRX release, so Peter can put it in the GRX main page if he wants, and I can package it for the DJGPP simtel library. Download. http://www.terra.es/personal/malfer/zipfiles/grx233.tgz Greetings, M.Alvarez P.D. I know, my english is terrific, sorry.

Updates for grx-2.3.2

Hi! I finally tried to merge my modifications into grx-2.3.2: - printing support from bcc2grx - adding const to parameters in some place. Perhaps it should be done more carefully (simply I tried to eliminate compiler warnings from my C++ programs which uses BCC2GRX) - makefiles for grx-2.3.2 doesn't provide rules for including BGI fonts in object library. Currently I didn't have time to mess much with makefiles, so I only put shell script in chr directory which does this for DJGPP - removing some other warnings Andris The following section of this message contains a file attachment prepared for transmission using the Internet MIME message format.

GRX VESA driver

I experienced a 'bug ?' in GRX 2.3.2 video handling: when you switch back and forth from DOS box to Windows (Alt TAB) the color table / color palette using 256 GrCells is spoiled. i.e. not the contents of the Cells are disturbed, but their resulting color on the screen. Does anybody know about a fix for that problem ? I think it should be possible, as in Allegro for example, it does not occur. And basically IMHO they should do something very similar, but I am not an expert. Thanks for any hints from you experts. -- Gruss Waldemar Schultz.

GRX 2.3.2 Fonts

I have some questions about GRX font usage: a) is there a free font editor for GRX fonts available b) how can I save a GRX font generated by GrLoadConvertedFont() to a 'file.fnt' c) how to use the output of GrDumpFont() properly d) are there some more fonts of the family "PC<W>x<H>[t].fnt" available for GRX (I like that thin pc8x14t.fnt :-) Thanks for any help -- Gruss Waldemar Schultz.
