Cannot open bitmap files

原文 2012-08-02 12:54:29 8 1 java/ bmp

I have a problem with opening bitmap files(widthxheight) in windows. Files are generated by a Java program which reads .dat files by 4bytes and write them as .bmp files. The weird thing is, if the width of the file is multiple of 4, the file can be opened (ie 400x450). However, if its not, I cant open the file and it says drawing failed (ie 450x400).

Any idea why this is happening? Thanks a lot.

BMP lines are padded to 4 bytes. Please make sure on write also on read to take care of that, see on net, wikipedia about BMP format.
