I am developing an image processing application, which process large sized bitmap.
I already serched and read many answers in this forum.
But, I cound't find the answer which I want to know.
I did test using this function, L_CreateBitmap, with a memory flag value of TYPE_DISK.
Large sized bitmap is solved by this function, but processing speed is too bad.

Can I use hdd like the PhotoShop? I checked the system memory when Photoshop was processing.
Photoshop, for processing, makes some space in HDD.

I think L_CreateBitmap function make some space, which programer dont' know, in the HDD.
I mean. I geuss that processing speed is too slow because L_CreateBitmap assign some space in hdd.
if programer make file to assign space and use before creating bitmap, do this processing speed is faster than nomal processing?
If this guess is right, how do i do?? What function can I use?

MaxLeo,
You probably already saw this post:
http://support.leadtools...orums/4433/ShowPost.aspx
but if you haven't, take a look at it and see if the ideas there help you.


Another idea is to use the L_LoadFile function with a callback and
process a buffer at a time, but that depends on what kind of processing
you want to do. If you give us more details, we might be able to suggestion something.
