  Function: gdImageCreateFromGd

<gdImageCreateFromGd> is called to load images from gd format
    files. Invoke <gdImageCreateFromGd> with an already opened pointer
    to a file containing the desired image in the gd file format,
    which is specific to gd and intended for very fast loading. (It is
    not intended for compression; for compression, use PNG or JPEG.)

<gdImageCreateFromGd> 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 gd format
    image). <gdImageCreateFromGd> 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:

<gdImageCreateFromGdPtr> creates an image from GD data (i.e. the
    contents of a GD file) already in memory.

<gdImageCreateFromGdCtx> reads in an image using the functions in
    a <gdIOCtx> struct.

Parameters:

infile - The input FILE pointer

Returns:

A pointer to the new image or NULL if an error occurred.

Example:

> gdImagePtr im;
    > FILE *in;
    > in = fopen("mygd.gd", "rb");
    > im = gdImageCreateFromGd(in);
    > fclose(in);
    > // ... Use the image ... 
    > gdImageDestroy(im);
