Need to crop+resize ~300000 files. Runtime = 4+ days. How can I speed up my bash script?
bash,imagemagick,runtime,imagemagick-convert,mogrify
A few things spring to mind... Firstly, don't start ImageMagick twice per image, once to resize it and once to crop it when it should be possible to do both operations in one go. So, instead of your two convert commands, I would do just one convert image.jpg -resize 1920x1440...
How to speed up a complex image processing?
php,image,imagemagick,converter,imagemagick-convert
0. Two approaches Basically, this challenge can be tackled in two different ways, or a combination of the two: Construct your commands as clever as possible. Trade speed-up gains for quality losses. The next few sections discuss the both approaches. 1. Check which ImageMagick you've got: 'Q8', 'Q16', 'Q32' or...

Zoomming into an image with ImageMagick

Compare images and remove duplicates
You don't say if you are on OSX/Linux or Windows, however, I can get you started. ImageMagick can calculate a hash (checksum) of all the pixel data in an image regardless of date or timestamp like this identify -format "%# %f\n" *.png 25a3591a58550edd2cff65081eab11a86a6a62e006431c8c4393db8d71a1dfe4 blue.png 304c0994c751e75eac86bedac544f716560be5c359786f7a5c3cd6cb8d2294df green.png 466f1bac727ac8090ba2a9a13df8bfb6ada3c4eb3349087ce5dc5d14040514b5 grey.png 042a7ebd78e53a89c0afabfe569a9930c6412577fcf3bcfbce7bafe683e93e8a hue.png...
memory problems with imageMagick?
windows,imagemagick,imagemagick-convert,color-palette,hdd
Just some general advice really on dealing with problems with ImageMagick and large images. If you are dealing with images that are tens of thousands of rows by tens of thousands of columns, that can pretty soon mount up and exceed the limits of a 32-bit OS and ImageMagick binary,...
Are PDF dimensions meaningful when measured in pixels?
pdf,image-processing,imagemagick,pixel,dimensions
'Wand' and 'GDAL' are not made to process PDFs If you rely on Wand (ImageMagick bindings) to process PDFs, you are not using ImageMagick as you may imagine. Because ImageMagick cannot process PDFs by itself -- it only processes raster images. For other formats IM has to rely on 'delegates'....
Imagemagick crop while keeping size

I think you need this to chop 10px off the top edge: convert rose: -chop 0x10 result.gif Just for completeness, if you want to chop 10px off the bottom, do this: convert rose: -gravity south -chop 0x10 result.gif And to chop 10px off the left edge: convert rose: -chop 10x...
Install Perl Image::Magick on Fedora
The problem is that CPAN doesn't know about non-Perl dependencies. The Perl Image::Magick module is just a wrapper around a C library. You'll need that library installed before you can build the Perl module. $ sudo yum install ImageMagick It also probably need ImageMagick's development package. $ sudo yum install...
How to apply pagecurl effect on a static image by PHP
I would apply this effect using an overlay image (probably a PNG with alpha) - this could be done either using ImageMagick or in the rendering layer (e.g. HTML/CSS etc) For PHP/Imagick extension, the Imagick::mergeImageLayers method is probably useful....
Photoshop script to export layer combinations
imagemagick,photoshop,photoshop-script
I think I have got the idea of what you want. I find ExtendScript pretty awkward to code in and would tend to do automated stuff outside of Photoshop with more powerful, everyday tools. I would go with ImageMagick and bash. ImageMagick is free and available for Windows, and the...
I can't convert with ImageMagick
First of all, two observations: The message you see is not from ImageMagick, it is from Ghostscript. The message is not an error message, but merely a warning. So it may well be that your conversion did work and you'll have the desired output in $image_path. Did you check? Then,...

easyimage : set re-sized image background to transparent
javascript,node.js,imagemagick,alpha-transparency
EasyImage does not support transparency. It passes the background color to ImageMagick via the -background flag, which does not do transparency. To use transparency in ImageMagick you need to use the -transparent flag, which EasyImage does not include in its options.
