NDPI format support in OpenSlide - are there any forecasts?

[toto sugito]

Hi Benjamin,
If you get changed the indentation in my code, that is because my editor.
reordered functions, etc. That is because my code still try and error because I am a new user at BIO-FORMAT data format.
So, forget about that.

I have a question for you. I have read your "openslide-ops-jpeg.c" file. This file show me information how to read a jpeg file.
I get the input from this code is jpeg file.

NDIP file have some of jpeg file. So, if we want to read selected jpeg file in NDPI file, we must extracted that file AND using code at "openslide-ops-jpeg.c" to read that jpeg file.
Or the code must be read that file without extract selected image in NDPI ?

Best regards,

Toto

Your code appears to be a lightly modified version of openslide-tiffdump.c
with our copyright statements removed and your name added.  Since you have
also unnecessarily renamed functions, reordered functions, changed the
indentation, etc., it's not clear to me what was changed or why.

If you want to have your changes accepted into OpenSlide, you need to
create a Git branch -- based on OpenSlide master -- containing a series of
small commits that each accomplish exactly one thing.  I can't merge your
changes if I can't understand them.

OpenSlide renders decoded image data to a Cairo surface.  You should be
able to use the existing JPEG backend (openslide-ops-jpeg.c) to do this.
