I would like to represent a structure containing 250 M states(1 bit each) somehow into as less memory as possible (100 k maximum). The operations on it are set/get. I cold not say that it's dense or sparse, it may vary. The language I want to use is C.

I looked at other threads here to find something suitable also. A probabilistic structure like Bloom filter for example would not fit because of the possible false answers.

Any suggestions please?

Let's say I get a HBITMAP object/handle from a native Windows function. I can convert it to a managed bitmap using Bitmap.FromHbitmap(nativeHBitmap), but if the native image has transparency information (alpha channel), it is lost by this conversion.

Hi! How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files) Thanks for any solutions! >>> More
