GitHub Instantly share code, notes, and snippets. Make a programme in C that reads a BMP image file, stores its content in the structure bmp_file which saves the header, colours palette (if it exists) and the matrix (real image). For our purposes, we can divide a BMP image in four regions: file header - all BMP images starts with a five elements file header. This has information about the file type, file size and location of the pixel data. Check Wiki for images. For a current project, I was looking for a way to decode 2-dimensional raster images in Elm to get values of individual pixels out of an image. I've created program in C witch reads .bmp file and apply on it blur effect. 2. Now, to make the image black and white, we need to convert pixel values into .

While we know the different file formats and the their meanings, C understands the image as a file only. .bmp file format assume an endian (little) and so each member of BMPHeader requires an endian adjustment should code compile on a non-little endian machine for both reading and writing. The reading part operates as a Verilog model of an image sensor/camera (output RGB data, HSYNC, VSYNC, HCLK).
