img_codec_get_criteria()
QNX SDP8.0Image Library ReferenceAPIDeveloperProgramming
Get the extension and mime information for a given codec
Synopsis:
#include <img/img.h> void img_codec_get_criteria( img_codec_t codec, const char **ext, const char **mime );
Arguments:
- codec
- The codec for which to return the criteria.
- ext
- A pointer to the codec's extension type.
- mime
- A pointer to the codec's mime type.
Library:
libimg
Use the -l img option to qcc to link against this library.
Description:
This function gets the extension type and mime type for a given codec.
Examples:
#include <stdio.h>
#include <stdlib.h>
#include <img/img.h>
int main (int argc, char *argv[])
{
img_lib_t ilib = NULL;
if(img_lib_attach(&ilib) == IMG_ERR_OK)
{
int count = img_codec_list(ilib, NULL, NULL, NULL, 0);
if( count > 0)
{
img_codec_t *codecs;
if((codecs = (img_codec_t *)calloc(count, sizeof(img_codec_t))) != NULL)
{
if((count = img_codec_list(ilib, codecs, count, NULL, 0)) > 0)
{
int i;
for( i = 0; i < count; i++)
{
char const * mime;
char const * ext;
img_codec_get_criteria(codecs[i], &ext, &mime);
printf("codecs[%d]: ext = %s: mime = %s\n", i, ext, mime);
}
}
free(codecs);
}
}
}
return (0);
}
Running this example produces the following output:
codecs[0]: ext = pcx: mime = application/pcx
codecs[1]: ext = tga: mime = application/tga
codecs[2]: ext = sgi: mime = image/sgi
codecs[3]: ext = png: mime = image/png
codecs[4]: ext = jpg: mime = image/jpeg
codecs[5]: ext = gif: mime = image/gif
codecs[6]: ext = bmp: mime = image/bmp
