A:
Since BMP is not a compressed format, is this a good idea?
Presumably, image size is even more important on portable devices.

Right now I am not concerned about the size. Just want to know can I write image data as .bmp file.

Fair enough, I hope someone with an iphone can let you know. Maybe Apple DOES support older Windows image formats - I don't know. Good Luck.

A:
I don’t think BMP is supported on iPhone. Maybe somebody wrote a category for UIImage that does saving into BMP, but I don’t know about any. I guess You’ll have to get the bitmap data from the UIImage and write them yourself, BMP is quite a simple file format. All you have to do is write out the header and then the uncompressed data. The header is a structure called BITMAPINFOHEADER, see MSDN. Getting the bitmap data of an UIImage is described in Apple’s Technical Q&A1509.
