High resolution images in VB.NET

[Johnny Granberg]

Im trying to make a software in VB.NET that is supposed to handle high-res
images, ive discovered theres a limit in the size of the bitmap object
around 10000x10000 pixels.

The program takes a number of input files and then create new files with
parts of the input files.

so basicly i load the input files in memory so the program will be as fast
as possible, but now and then i get "out of memory" exceptions even tho the
program only seem to use about 300Mb of ram

the images i load is about 8000x7500 pixels tho i would like to load even
larger files but the bitmap object seems to have the limit i spoke of.

Is there any way to get around that limit? is there any object besides
bitmap i can use to manipulate images, and could i use directx for my
application if i wanted to make stuff go faster?

If so, where can i find information on image editing in directx?

Thanks!

Other people have run into this same issue.
You should check out microsoft.publi c.dotnet.framew ork.drawing group.
You might have better luck getting a resolution, or at least an explanation
there.
