Unified Image Codec interface and debug version of malloc/free

[haerle]

Hello,

I'm currently trying out the Unified Image Codec interface. In debug mode my application crashes on deletion of a ImageBuffer object instance when it is built and running in debug mode. This happens both if the object is created on the heap and on the stack.

Do you have any idea how to avoid this problem? Creating the object on the heap and not deleting it is not a good workaround I think.

Thx for your help,

Fabian

Hi Fabian,

do you use the latest IPP 6.0 update 2 UIC sample?

Hi Vladimir,

I am using the samples of w_ipp-samples_p_6.0.0.130. Can you tell me how to modify the makefile to compile the libraries in debug mode? This would also help me debug my application.

Fabian

Hi Vladimir,

the following seems to work: I compiled the uic libaries in debug mode with the following changes in the according makefiles (e.g. ipp-samplesimage-codecsuicsrciouic_iouic_io.mak):

- change CXXFLAGS = /c /O2 /MD to CXXFLAGS = /c /O2 /MDd /Zi
- add /DEBUG to LDFLAGS

Now I both have a dll version for my release compiles and my debug compiles (plus pdb files). The application doesn't crash any more.

best,

Fabian

Hi Fabian,

glad to hear you solve issue.

Just notice, we are going to extend UIC sample with support for PNG format (based on zlib and libpng libraries optimized by IPP). Please stay tuned for upcoming IPP 6.1 release.

Although, your feedback is important for us to better understand our customer needs.

Hi Vladimir,

concerning customer needs: I would also appreciate multiplane TIFF saving with LZW and ZIP compression for 16 bit grayscale images.
