[Mesa3d-dev] [Bug 27312] glCopyTexImage2D Doesnt seem to work correctly (returns incorrect alpha component )when internal format is GL_RGB
http://bugs.freedesktop.org/show_bug.cgi?id=27312 --- Comment #8 from Chia-I Wu olva...@gmail.com 2010-03-28 01:51:22 PST --- (In reply to comment #0) tmpBuf = (GLubyte *)malloc(4*sizeof(GLubyte)); glReadPixels(12, 12, 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, tmpBuf); /*## ## ## tmpBuf[0]=tmpBuf[1]=tmpBuf[2] = 143 //Expected tmpBuf[3] = 143 //Not expected - This should be 255 as we are not using this component. I have checked this with other vendors NVIDIA and ATI and they indeed report correct behavior (tmpBuf[3] = 255) ## ## ##*/ I've tested the demo with current git head, using egl_x11_swrast driver and libGLESv2. It has the correct behavior (tmpBuf[3] is 255). Do you want to try again with git head or the to-be-released 7.8? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

http://bugs.freedesktop.org/show_bug.cgi?id=27312 --- Comment #3 from Karthik Hariharakrishnan karha...@arm.com 2010-03-26 09:22:01 PST --- (In reply to comment #2) Which driver are you using? swrast or softpipe or other? I could probably look into this as soon as you provide a (glut) test program. Hi, I am using the egl driver for window management. I built egl_softpipe.so in src/gallium/winsys/egl_xlib. And am linking with the gallium libraries. I will try uploading the source file soon. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
