Any clue to how to directly read and modify a file in disk without loading it into memory?
I have many huge images, and I need to view them inside a viewport without hogging the memory.
This is my first experience to feel the real NULL pointer returned by the malloc
I saw some of applications crashed due to my files, and yet some of capable viewer just doesn't match the requirements.
My program runs in a 64MB RAM and 4GB HDD computer so that even windows' page file won't help.
My plan is to divide the huge image into smaller chunks, then load it as usual with some kind of algorithm to optimize the viewing speed.
Any clue please?
Thanks in advance.
