Functions

gdImageWBMPCtx
void gdImageWBMPCtx(gdImagePtr image,
int fg,

Write the image as a wbmp file
Parameters

gdImageCreateFromWBMPCtx

gdImageCreateFromWBMP
gdImagePtr gdImageCreateFromWBMP(FILE *inFile)
gdImageCreateFromWBMP is called to load images from WBMP format files.  Invoke gdImageCreateFromWBMP with an already opened pointer to a file containing the desired image.  gdImageCreateFromWBMP returns a gdImagePtr to the new image, or NULL if unable to load the image (most often because the file is corrupt or does not contain a WBMP image).  gdImageCreateFromWBMP does not close the file.  You can inspect the sx and sy members of the image to determine its size.  The image must eventually be destroyed using gdImageDestroy.
Variants
gdImageCreateFromWBMPPtr creates an image from WBMP data (i.e. the contents of a WBMP file) already in memory.
gdImageCreateFromWBMPCtx reads in an image using the functions in a gdIOCtx struct.
Parameters
infileThe input FILE pointer
Returns
A pointer to the new image or NULL if an error occurred.
Example
gdImagePtr im;
Packit ed3af9 
FILE *in;
Packit ed3af9 
in = fopen("mywbmp.wbmp", "rb");
Packit ed3af9 
im = gdImageCreateFromWBMP(in);
Packit ed3af9 
fclose(in);
Packit ed3af9 
// ... Use the image ...
Packit ed3af9 
gdImageDestroy(im);

Write the image as a wbmp file
gdImagePtr gdImageCreateFromWBMPCtx(gdIOCtx *infile)
Reads in a WBMP image via a gdIOCtx struct. 
gdIOCtx structures hold function pointers for doing image IO.

void gdImageDestroy (gdImagePtr im)
gdImageDestroy is used to free the memory associated with an image.
