Access JpegXR buffer after encoding

Access JpegXR buffer after encoding

Ritratto di Joan Liu

Ihave writtena program to successfully encode RGB buffers to JpegXR files.

I'm usingthe uic sample codes provided in "w_ipp-samples_p_7.0.7.064\\\\ipp-samples\\\\image-codecs\\\\uic\\\\src\\\\application\\\\uic_transcoder_con".

However, now, I need to access the JpegXR image buffer (with headers and everything) after encoding, and not write them to file at all. Is this JpegXR image buffer "BaseStreamOutput& out" in "jpegxr.cpp"? How can I prevent writing to JpegXR files?

"jpegxr.cpp" //found in sample code
IM_ERROR SaveImageJPEGXR(

  CIppImage&        image,

  PARAMS_JPEGXR&    param,

  BaseStreamOutput& out)

{

// Some code....
if(ExcStatusOk != encoder.WriteHeader())

      return IE_WHEADER;
if(ExcStatusOk != encoder.WriteData())

      return IE_WDATA;
if(ExcStatusOk != encoder.FreeData())

      return IE_RESET;
// Some more code...

}

Hello,

In the UMC sample code, there is a memory buffer output (\ipp-samples\image-codecs\uic\src\io\uic_io). You can use the memory buffer output, other than file output.

Thanks,
Chao
