Legacy ImageMagick Discussions Archive

Hi,

I've just started using Imagemagick - thank you, it looks great!

I'm using an android port from here:

https://github.com/puelocesar/android-lib-magick

and I have to use the API directly, so running into some issues. Could anyone help me define the api call to correctly resize an image preserving the aspect ratio? I think I'm close, but can't find an example anywhere after much searching. Here's what I got:

img = new MagickImage(new ImageInfo(filename));
scaledImage = img.zoomImage(dimensions.getHeight(), dimensions.getWidth());
scaledImage.unsharpMaskImage(0, .75, .75, .008);

It almost works, but the aspect ratio is not preserved. I know that its fairly easily done from the command line, but having some troubles seeing the way via the api...

Thank you!

Get the image dimensions and compute the aspect ratio of the resized image with simple math. If the API supports TransformImage() you can set a resize geometry as a string and ImageMagick will set the resize dimensions while maintaining the aspect ratio for you.
