resize crash for large iamge

[danielwang1971]

Hello,
I have trouble for ippiResizeSqrPixel:

Source Image size : 6576 X 2192 Mono 8 bit

Destination image : 40768X13589

The image size : ippiResizeSqrPixel_8u_C1R crashed no error.

I also try  ippiResizeSqrPixel_8u_AC4R with BGRA image  crash when Destination image image size is 11836X2945

Do you have any idea?

Thanks.

>>Source Image size : 6576 X 2192 Mono 8 bit >> >>Destination image : 40768 X 13589 For the destination image: 40768 * 13589 = 553,996,352 bytes ( ~528MB ) and it is well below a 2GB limit of a Windows 32-bit platform but it could exceed (!) some internal limits of IPP and I'll do a verification. Did you get that crash on a 32-bit or 64-bit platform?

>>Do you have any idea? So far I can not suggest anything. >>... it could exceed (!) some internal limits of IPP and I'll do a verification... A test-case I have shows that a limit for an image is 34207 x 34207 ( ~1.089GB ) and more technical details are needed ( what about a test-case? ). Best regards, Sergey

Could you verify Virtual Memory settings on your platform? What your current settings are?

Thanks. I find problem. You are right. The problem is image buffer over 2GB. It's fail to allocate over 2 GB buffer. Thanks again.
