bug with GrDrawString() and underlining
by Al-Junaid H. Walker 15 May '08

15 May '08

GRX 2.4.8/DJGPP ; GrDrawString(void *text,int length,int x,int y,const GrTextOption *opt); - when opt->txo_font.txo_fgcolor.v = 0x10000000 | GrXOR then the underline flag (0x10000000) causes the XOR operation flag to stop functioning, and behave like GrWRITE. Maybe GRX is accidently reseting the GrXOR flag instead of the GrXOR<<4 (underline) flag? Can anyone confirm? Fixes? Reply to haidera(a)australia.edu

Well, there are two possibilities to compile GRX, since 2.4.7 The old one, devised for people who have a very minimal DJGPP setup, djdev, gcc, binutils and make, usually working in bare DOS with small machines. The new one is for people having a full system, frequently working in a DOS box under some Windows OS. The first have to set HAVE_UNIX_TOOLS=n and use the bare DOS command interpreter command.com, whether in pure DOS or in a DOS box under Windows The other can set HAVE_UNIX_TOOLS=y, and work under bash launched from DOS, and this is much more comfortable: possibility to use the configure script to automate some editing (interesting mainly for Pascal users): this is what I do usually. But the OP referred to 2.4.6 for which this second, better, possibility was not present, and instructions were for bare DOS users, working under Command.com, without bash which interprets differently some commands. I just said that you can as well compile 2.4.6 the old way under cmd.exe, the windows command interpreter, in a DOS box in a windows OS. But switching to 2.4.8 and compiling under bash is the best solution. > On Tue, Apr 15, 2008 at 6:00 PM, Maurice Lombardi > <Maurice.Lombardi(a)ujf-grenoble.fr> wrote: > >> >>franck Ismael a écrit: >> >>>How can I used "COMMAND.COM" as my command interpreter (SHELL=COMMAND.CON) >> >>on Windows XP to run "makefile.dj2" which is part of what I have to do to >>install the graphics library GRX 2.4.6 on Borland C/C++ and DJGPP v2.03 >>compiler. > > -- Maurice Lombardi Laboratoire de Spectrometrie Physique, Universite Joseph Fourier de Grenoble, BP87 38402 Saint Martin d'Heres Cedex FRANCE Tel: 33 (0)4 76 51 47 51 Fax: 33 (0)4 76 63 54 95 mailto:Maurice.Lombardi@ujf-grenoble.fr

PLEASE HELP. PROBLEM TO SET "SHELL=COMMAND.COM" ON WINDOWS XP
by franck Ismael 16 Apr '08

How can I used "COMMAND.COM" as my command interpreter (SHELL=COMMAND.CON) on Windows XP to run "makefile.dj2" which is part of what I have to do to install the graphics library GRX 2.4.6 on Borland C/C++ and DJGPP v2.03 compiler. ___________________________________________________________ Yahoo!

Can't set mode to 24 bits
by André Moreira 14 Feb '08

14 Feb '08

Hello I have an application running on a machine with a 24bit graphical card, and I want to set the video mode to 24bits, but.... It doesn't seem to be working. I set the driver as (...) GrSetDriver( "win32 gw 800 gh 600 nc 16M" ); (...) and the mode as (...) GrSetMode( GR_NC_width_height_bpp_graphics, XRES, YRES,24); (...) but when I check if it's in 24 bits... it tells me that it's in 32bits. If in the driver I change to 64k or 32k or 256 it will render the same result... I am at a loss. Any ideas? thanks in advance André

Re: adding unicode fonts support to grx
by Josu Onandia 20 Nov '07

20 Nov '07

Hi, The support for Unicode is already implemented. Or perhaps I'm not understanding the question. Well, more specifically, GRX supports characters coded in 16 bits. All you need to do is to fill the field 'txo_chrtype' of GrTextOption with the constant GR_WORD_TEXT. You will need to obtain an Asiatic font, in truetype or X11 formats, and convert it to the GRX format. Best regards Josu Onandia -----Original Message----- From: grx-owner(a)gnu.de on behalf of André Moreira Sent: Tue 11/20/2007 1:15 PM To: grx(a)gnu.de Subject: adding unicode fonts support to grx Well, I need to add asian character to my application and as I'm doing that I started thinking about adding unicode support to GRX. Althought I could simply pick and place "bitmaps" of asian characters, that wouldn't be flexible so... how can I add unicode support to GRX? What do I need to change, where do I need to change them etc... I'm starting to read somethings about it and hopefully (sic) it wouldn't be that much work... Anyone care to join?

X11 font loading
by André Moreira 20 Nov '07

20 Nov '07

Hi all again, Just a quick question. How does grx handles X11 fonts? Can I just load a font.pcf.gz or do I need to convert it? If GRX can handle X11 fonts does this means that 16bits fonts are also supported such as asian fonts? André

Re: keyboard failing in grx 2.4.8 under linux X11
by André Moreira 09 Nov '07

09 Nov '07

Hi, As far as I can tell, the installation went without glitches. This software I am working on as a couple of years and it started with 2.4.4. or 2.4.5. When I ported it to Linux I started noticing some problems with refresh (solved in grx2.4.8). Mouse events (not working in demogrx) are working in my application. Now about keyboard..... I suppose it's not a grx bug (hopefully). I am thinking that it might be hardware related as I am working on a sony vaio vgn-c2s. But I have to find a desktop to build grx and test this. For me it is out of the question to revert to a previous grx version because of the refresh issues, so I am quite stuck without the keyboard. I will try to work around it and I'll keep this forum informed of any breakthroughs.
