I'm trying to write app, which can
1. load an image (such as jpg)
2. display this image on the screen
3. modify the image - bitmap (low level, operations such as filters)
4. display image ...
What is the easiest way? What classes I should use?
I tried class CPAlbImageViewerBasic, which can open and display image.
It's great to rotate, scroll, zoom image.
But it can return only visible part of bitmap.
I need the whole of bitmap.
Also I didn't find way to give a bitmap to be displayed by this class.
So I need to get bitmap from a file (jpg).
This bitmap I want to modify and display.
(Also scroll and zoom...)
At the end save into jpg file.
What classes and function do you recommend?
Thanks a lot for response
