My question stems off the fact that we have both custom fonts and jpeg images in our product. The fonts alone take up 150K of the heap (they are stored as data records, and then casted for FntDefineFont - since that memory must stay locked until use of the font is done, it takes up the memory), I was trying to consider a way to store the fonts in such a fashion where I could keep them and not lose so much space on the heap.
I'm also trying to think of a way to store the resulting bitmap (from the jpeg library) - in such a way where I don't have to keep a handle to it in memory (on the heap) so that scrolling down a page is not such a problem. Here I'm considering dumping the bitmaps to a temp database as a bitmap resource. Then reading the bitmap resource and drawing it only as needed. That would remove the requirement of keeping it in heap for such an extended period of time as well. (especially since there could be as many as 10 or so images on a single page that need to scroll smoothly.) All of which is 160x160 and 16bit. Unfortunately my efforts to store the bitmap as a bitmap resource in the tempDb is failing. I end up with a corrupted image (hence a previous email last night). So I really need to see if I can address one or both of these issues. Any help would be appreciated.. thanks - bill "Ben Combee" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > At 01:22 PM 1/29/2004, Fruber Malcome wrote: > >Do both resources (e.g. Tbmp or nfnt etc) use the same amount of heap as a > >data record?
