bmpio.c
bmpio.c Read bmp from file PIX *pixReadStreamBmp() Write bmp to file l_int32 pixWriteStreamBmp() Read/write to memory PIX *pixReadMemBmp() l_int32 pixWriteMemBmp() On systems like windows without fmemopen() and open_memstream(), we write data to a temp file and read it back for operations between pix and compressed-data, such as pixReadMemPng() and pixWriteMemPng().
PIX * pixReadMemBmp ( const l_uint8 *cdata, size_t size )
pixReadMemBmp() Input: cdata (const; bmp-encoded) size (of data) Return: pix, or null on error Notes: (1) The @size byte of @data must be a null character.
PIX * pixReadStreamBmp ( FILE *fp )
pixReadStreamBmp() Input: stream opened for read Return: pix, or null on error Notes: (1) Here are references on the bmp file format: http://en.wikipedia.org/wiki/BMP_file_format http://www.fortunecity.com/skyscraper/windows/364/bmpffrmt.html
l_int32 pixWriteMemBmp ( l_uint8 **pdata, size_t *psize, PIX *pix )
pixWriteMemBmp() Input: &data (<return> data of tiff compressed image) &size (<return> size of returned data) pix Return: 0 if OK, 1 on error Notes: (1) See pixWriteStreamBmp() for usage. This version writes to memory instead of to a file stream.
l_int32 pixWriteStreamBmp ( FILE *fp, PIX *pix )
pixWriteStreamBmp() Input: stream opened for write pix (1, 4, 8, 32 bpp) Return: 0 if OK, 1 on error Notes: (1) We position fp at the beginning of the stream, so it truncates any existing data (2) 2 bpp Bmp files are apparently not valid!. We can write and read them, but nobody else can read ours.
