iPhone ImageMagick Library - converting from batch file script to Objective-C using MagickWand API

I've decided to use the following ImageMagick library for iPhone development:

https://github.com/marforic/imagemagick_lib_iphone

It works quite well. The sample project compiles just fine, but doesn't make any sense whatsoever.

Usually, I'll use the "convert.exe" that comes with ImageMagick for Windows to convert images via the command line. So I'll write a little batch file like the following:

@echo off

set SOURCE=image_to_convert.jpg

del result.jpg
del source_copy.jpg

convert.exe %SOURCE% -fill "#fff8f2" -colorize 100%% fill.jpg

copy %SOURCE% source_copy.jpg

convert.exe %SOURCE% -modulate 100,0,100 -|^
convert.exe - source_copy.jpg -compose overlay -composite -|^
convert.exe source_copy.jpg - -compose dissolve -define compose:args=37,100 -composite -|^
convert.exe - -modulate 100,70,100 +level 3.5%%,100%% -|^
convert.exe - -channel red -level 0%%,89%% +level 9%%,100%% -|^
convert.exe - -channel green +level 3.5%%,100%% -|^
convert.exe - -channel blue -level 0%%,93%% +level 4.7%%,100%% -|^
convert.exe - -brightness-contrast -5x3 -|^
convert.exe fill.jpg - -compose multiply -gravity center -composite -|^
convert.exe - -level 3.5%%,100%%,0.91 +level 2.7%%,100%% -|^
convert.exe - -channel red +level 3.5%%,100%% -|^
convert.exe - -channel green -level 0%%,87%% +level 1%%,100%% -|^
convert.exe - -channel blue -level 0%%,100%%,0.94 +level 7%%,100%% -|^
convert.exe - -brightness-contrast -1x0 final_converted_image.jpg

del source_copy.jpg
del fill.jpg

The problem is converting the above batch file to be used alongside that particular library.

- (void)convertImage {
    MagickWandGenesis();
    magick_wand = NewMagickWand();
    //UIImageJPEGRepresentation([imageViewButton imageForState:UIControlStateNormal], 90);
    NSData * dataObject = UIImagePNGRepresentation([UIImage imageNamed:@"iphone.png"]);
    MagickBooleanType status;
    status = MagickReadImageBlob(magick_wand, [dataObject bytes], [dataObject length]);
    if (status == MagickFalse) {
        ThrowWandException(magick_wand);
    }

    // Resize image.
    ImageInfo *imageInfo = AcquireImageInfo();
    ExceptionInfo *exceptionInfo = AcquireExceptionInfo();

    // Get image from bundle.
    char *input_image = strdup([[[NSBundle mainBundle] pathForResource:@"iphone" ofType:@"png"] UTF8String]);
    char *output_image = strdup([[[NSBundle mainBundle] pathForResource:@"iphone" ofType:@"png"] UTF8String]);
    char *argv[] = { "convert", input_image, "-resize", "100x100", output_image, NULL };

    // ConvertImageCommand(ImageInfo *, int, char **, char **, MagickExceptionInfo *);
    status = ConvertImageCommand(imageInfo, 5, argv, NULL, exceptionInfo);

    free(input_image);
    free(output_image);

    if (status == MagickFalse) {
        ThrowWandException(magick_wand); // Always throws an exception here...
    }

    size_t my_size;
    unsigned char * my_image = MagickGetImageBlob(magick_wand, &my_size);
    NSData * data = [[NSData alloc] initWithBytes:my_image length:my_size];
    free(my_image);
    magick_wand = DestroyMagickWand(magick_wand);
    MagickWandTerminus();
    UIImage * image = [[UIImage alloc] initWithData:data];
    [data release];

    [imageViewButton setImage:image forState:UIControlStateNormal];
    [image release];
}

The problem is that status is always MagickFalse, which means it throws an exception. I'm also not sure whether I'm using ConvertImageCommand() in the correct way either.

Any help would be greatly appreciated. Thanks in advance.

I ended up using MagickCommandGenesis() to achieve the desired result.
