Re: need help with freetype + xlib.
First Last wrote:
Hi, I try to use freetype with xlib, I , I need to pass a char type
array (RGBA/pixel) to a xlib function.
from freetype I got :
face-glyph-bitmap.pixel_mode = 2
so if I understood corectly in face-glyph-bitmap.buffer datas are stored in
gray level.
face-glyph-bitmap.rows=16
face-glyph-bitmap.width=8
face-glyph-bitmap.pitch=8
so I guess, length of face-glyph-bitmap.buffer =
1(gray lvl)*16(width)*8(rows)=128 unsigned chars, right ?
Right answer, wrong reasoning; width should be replaced by pitch. The
two values may differ if there is padding between lines.
then I create an array of char for xlib from face-glyph-bitmap.buffer
for(i=0;i128;i++){
Xdata[4*i] = face-glyph-bitmap.buffer[i];
Xdata[4*i+1] = face-glyph-bitmap.buffer[i];
Xdata[4*i+2] = face-glyph-bitmap.buffer[i];
Xdata[4*i+3] = 255;
}
and I try to create a XImage :
ximage = XCreateImage(display, DefaultVisual(display,0), 24, ZPixmap, 0,
Xdata[0], 8/*rows*/, 16/*width*/,
32/*RGBA*/, 8/*pitch??*/);
The last argument (bytes_per_line) should be 32 (8 pixels wide at 4
bytes per pixel).

thank you Werner, it's working fine now.

[Bug 52952] Ubuntu 10.04.4 LTS 32-bit and ATI Technologies Radeon Xpress 200 for Intel (RC410) ACPI S3 State Resume Failure
https://bugs.freedesktop.org/show_bug.cgi?id=52952 --- Comment #17 from mypersonalmailb...@mail.com --- (In reply to Comment #15) Hi Dant, Since no Linux device driver developers that I know of fix the bugs I report, I kinda gave up on uploading reports to get them to fix. That being said, based on my memory, this is what happens. - This ACPI S3 State bug appears to be related to ATI Technologies Radeon Xpress 200, and affects both AMD and Intel editions - This bug can be worked around by using a PCI Express graphics card instead (assuming that the particular graphics chip doesn't have any issues with ACPI S3 State resume) - See Comment #12 that this bug seems to impact Award/Pheonix BIOS-based mainboard - The Comment #12 implies that AMI BIOS is probably configuring the Radeon Xpress 200 differently than Award/Pheonix BIOS during POST, hence, the graphics device driver happened to work okay with AMI BIOS, but there probably is a bug in the way the graphics device driver is written - All known systems that have this bug have Award/Pheonix BIOS (Intel mainboard, HP Pavilion PC (I forgot the model.), and emachines PC (after flashing the BIOS via flashrom software), if I remember it correctly - The fact that Linux 3.9 kernel still has this bug means that the code for Radeon Xpress 200 hasn't really been updated to fix this embarrassing bug I have at least 3 different ATI Technologies Radeon Xpress 200-based mainboards in my apartment for testing purposes if anyone is willing to fix the bug.

[Bug 54273] kms blackscreen ATI RV620 FirePro 2260, res: 2560*1600
https://bugs.freedesktop.org/show_bug.cgi?id=54273 --- Comment #39 from John-Michael Mulesa thesaxophon...@gmail.com --- I believe I'm having this issue as well. I have an RV620 Radeon 3470 with two displayport outputs (which are the only two outputs on the card.) Both of my native Displayport displays (HP L2201x and a Dell U2311H, 1920x1080x60 native) go to Input not supported mode as soon as KMS kicks in. However, connecting a DVI display to an active DP-DVI adapter works perfectly. Using fglrx-legacy allows native displayport to work on the card. I've tried on kernel 3.9.0 and 3.10rc6 with the same results. -- You are receiving this mail because: You are the assignee for the bug. ___ xorg-driver-ati mailing list xorg-driver-ati@lists.x.org http://lists.x.org/mailman/listinfo/xorg-driver-ati
