This function deletes the HIGEAR handle and all memory associated with it.

AT_ERRCOUNT ACCUAPI IG_image_delete(
   HIGEAR hIGear
);

Arguments:

Name Type Description
hIGear HIGEAR HIGEAR handle of image to delete.

Return Value:

Returns 0 if successful. Otherwise, returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Sample:

All ImageGear DLL samples.

Example:

 
Copy Code
    // Create a new image with the same parameters as an existing image,
    // but with no pixel data allocated 
    AT_ERRCOUNT nErrcount;  // Number of errors on stack
    HIGEAR hIGear;          // Handle of image

    // Load image file "picture.bmp" from working directory
    nErrcount = IG_load_file("picture.bmp", &hIGear);
    if(nErrcount == 0)
    {
        // ...
        // Destroy the image
        IG_image_delete(hIGear);
    }

This function also frees the memory associated with the image's DIB, if ImageGear allocated the DIB memory. If ImageGear did not allocate the DIB memory, the DIB continues to exist, and it is the responsibility of your application to free this memory when done with it.
