Just want to put out this again but with a refined change.
In *ImageTransformsGPU.cpp *we have following
*:*
const int bytesPerDestPixel = 16 + 16 + 8
+ ((XGLMap[destGLTransferFormat] !=
GL_RGBA32F_ARB) ? BytesPerPixel[destGLTransferFormat] : 0)
+ ((destAlphaBuffer != NULL) ? 1 : 0);
const long long int maxDestPixels = gpuMemoryRemaining /
bytesPerDestPixel;
*Change to below for mac M1 ARM 64-bit:*
const int bytesPerDestPixel = 16 + 16 + 8
+ ((XGLMap[destGLTransferFormat] !=
GL_RGBA32F_ARB) ? BytesPerPixel[destGLTransferFormat] : 0)
+ ((destAlphaBuffer != NULL) ? 1 : 0);
#ifdef __aarch64__ // Check for ARM 64-bit architecture
* const long long int maxDestPixels = gpuMemoryRemaining /
bytesPerDestPixel / 2;*
#else
const long long int maxDestPixels = gpuMemoryRemaining /
bytesPerDestPixel;
#endif
I asked you already the last time to use a diff file and not to copy this
into the mail. The mail program does often mangle the format. And the exact
line in the code is unknown, I have to guess. (It may works in this simple
case, but for more complicated one this becomes more complicated.)
By reducing bytesPerDestPixel by half I can process huge files on my M1.
Tested 20000 X 13333 pixel files and they come out just fine. My first fix
would segfault on these files.
Of course this could be tested more and maybe you want a version to try
mikko? You are actually the first person I hear about selecting the GPU
option working on M1.
If tested around some maybe it would be a legit fix? What´s your opinion
T.Modes?
If you can explain why a factor of 2 is needed only for the Mac M1, yes.
And why 2 and not any other random number?
And it works for me is not enough. There are many more use case than your
limited testing with only 20000 pixel and only a limited format variation.
