I’ve written a simple C program which uses MagickWand to convert 11 successive GIF images into a single animated GIF file. This is the code. #include “MagickWand/studio.h” #include “MagickWand/MagickWand.h” # include “MagickWand/mogrify-private.h” #include “MagickCore/string-private.h”. Use MagickWand to convert, compose, and edit images from the C language. There is also the low-level MagickCore library for wizard-level developers.

MagickWand Examples in C
JPG files will set those transparent pixel into black as default. RMagick is an interface between cojvert Ruby programming language and the ImageMagick image processing libraries.
By “equivalent” I mean that the program produces the same image as the command line example – it won’t necessarily be exactly how it is achieved by the convert program. In most of these cases I have created one C function which replicates all the commands but each section of code will show how it relates to the original commands. Some of the examples show a command line “program” and how to achieve the equivalent output using MagickWand.
I think you’ll agree that even in this simple example, the MagickWand version is much easier to read and write.
