Converting images to another format with phMAgick

August 9, 2009 by nuno costa 15 comments

phMagick->convert()

Use this function to convert an image to another format

 

$p = new phmagick('source.jpg', 'destination.png');
$p->convert();

 

This example converts source.jpg to destination.png, optionaly setImageQuality() can be used to specify the quality of the new image

    @johny

    I’ve never tried converting pdf to gif’s, but there is no reason why it can’t be done

    conversion to pdf works! pdf-to-png gives me smallest output size.

    but pdf’s larger than about 200 Kb come out distorted. is there any way to control the resolution, color depth, or any other conversion options?

    thanks!

    i’m also finding very large pdf’s (600 Kb, maybe less) don’t get processed at all.

    Hi! Whenever converting a cr2 image to jpg with phMagick it always darkens the result image. Is there any way to avoid the darkening?

    @des-

    it only happens with jpg?

    ps: you might get more information on imagemagick site

    Tried to convert CR2 to TIF (on 3 different files), same thing happened.

    @des

    I’m afraid I can not be of much help, have you tried the imagemagick forums?

    Have you run phMagick in debug mode, maybe imagemagick is complaining about the image format or some values the delegate can not support

    SVG to PNG/JPEG/GIF support?

  13. by nuno costa on August 1 2011 at 20:49

    It should be supported as long as you have the correct libraries, please check imagemagick.org

    Is there any option to add more parameters? For instance I want to convert an image from png to -ordered-dither h4x4a bitmap, as specified here – http://www.imagemagick.org/Usage/quantize/#halftone, for use with a thermal printer. Thanks.
