Loading an image from a C source file, exported from GIMP


Tag : c , By : kgw
Date : March 29 2020, 07:55 AM
hop of those help? Here is an alternative solution. Export the image as a raw data file, then use bin2hex to convert it to a C/C++ array. This will work fine because instead of a huge string this script generates a char array. Here is an example:
$ bin2hex.pl
bin2hex.pl by Chami.com

usage:
  perl bin2hex.pl <binary file> <language id>

  <binary file> : path to the binary file
  <language id> : 0 = Perl, 1 = C/C++/Java, 2 = Pascal/Delphi

$ bin2hex.pl x.bin 1

/* begin binary data: */
char bin_data[] = /* 112 */
{0x23,0x69,0x6E,0x63,0x6C,0x75,0x64,0x65,0x20,0x3C,0x73,0x74,0x64,0x69,0x6F
,0x2E,0x68,0x3E,0x0A,0x23,0x69,0x6E,0x63,0x6C,0x75,0x64,0x65,0x20,0x3C,0x74
,0x69,0x6D,0x65,0x2E,0x68,0x3E,0x0A,0x0A,0x69,0x6E,0x74,0x20,0x6D,0x61,0x69
,0x6E,0x28,0x69,0x6E,0x74,0x20,0x61,0x72,0x67,0x63,0x2C,0x20,0x63,0x68,0x61
,0x72,0x2A,0x20,0x61,0x72,0x67,0x76,0x5B,0x5D,0x29,0x0A,0x7B,0x0A,0x20,0x20
,0x20,0x20,0x70,0x72,0x69,0x6E,0x74,0x66,0x28,0x22,0x25,0x64,0x5C,0x6E,0x22
,0x2C,0x20,0x73,0x69,0x7A,0x65,0x6F,0x66,0x28,0x74,0x69,0x6D,0x65,0x5F,0x74
,0x29,0x29,0x3B,0x0A,0x7D,0x0A,0x0A};
/* end binary data. size = 112 bytes */

will help you If you would like to export the pixel values to a text file (very different from writing it as an jpg or png file, for sharing and archival), all you need to do is dlmwrite(filename,I);
