convertfiles.c Conversion to 1 bpp l_int32 convertFilesTo1bpp() These are utility functions that will perform depth conversion on selected files, writing the results to a specified directory. We start with conversion to 1 bpp.
l_int32 convertFilesTo1bpp ( const char *dirin, const char *substr, l_int32 upscaling, l_int32 thresh, l_int32 firstpage, l_int32 npages, const char *dirout, l_int32 outformat )
convertFilesTo1bpp() Input: dirin substr (<optional> substring filter on filenames; can be NULL) upscaling (1, 2 or 4; only for input color or grayscale) thresh (global threshold for binarization; use 0 for default) firstpage npages (use 0 to do all from @firstpage to the end) dirout outformat (IFF_PNG, IFF_TIFF_G4) Return: 0 if OK, 1 on error Notes: (1) Images are sorted lexicographically, and the names in the output directory are retained except for the extension.
