Can't Find Image Data #47

Open PaulTheLionHeart opened 6 years ago

PaulTheLionHeart commented 6 years ago

I am trying to make a simple Heic image viewer. I was able to link the libraries okay and find the height and width of an image. However, I can't find the routines that get the bits per pixel or the decoded image data.

Do I need codec just to view simple images? Is there a simple way to get the image data?

Thanks.

Hi again, If I do need a codec, how do I interface with it in C++? Is there a simple codec just for heif/heic image files? Thanks, Paul.

Hi, Heif library itself doesn't contain codecs. You need to use external decoder to decode encoded image data you get from heif file parser library. See issue #45 for links to common platform decoders documentation links. BR,

Thanks for answering, BR. Please guide me as to where I can find a decoder and how I interface with it in c/c++. I am new to working with external decoders. I am more familiar with JPEG/GIF/PNG etc that have full libraries to decode them. Any help is greatly appreciated. Many thanks. Paul.
