I am under way to build libraw support for another media management system called Photoslide (github.com/lanthale/photoslide) and wanted to add libraw support.

Using java and the foreign memory api I can access libraw without any issues.

Nevertheless I am facing the issue how I can access the rgb (rgba) values of the in memory image because I do not want to write first a tiff file and then read the pixels again from the temp file.

Therefore I have seen it is possible to use the libraw_dcraw_make_mem_image to create a representation of the pixels in memory. But the documentation say's that I am getting back a struct libraw_processed_image_t which includes data[] as field. But there is no documentation what is realy given back (array of bytes, array of ints, array of floats).
Please can you help me with the format of the data or can you point me where I can get the data otherwise if this method should not be used ?

I am not a C developer and maybe this is a beginners question but I would appreciate to get an answer.

Target would be to get processed pixels in 8-bit or 16-bit rgb (rgba) values.

Thank you in advance.
