I know this is old post but I spend my all day to make it work, so here are the steps that helped me: Download ImageMagick Binary Release – http://www.imagemagick.org/script/download.php Install in C:\imagemagick, on last step check “Add application directory to your system path“ Download Imagick DLL: PHP5.6.x version from http://www.peewit.fr/imagick/ (I have 5.6+ version … Read more
Well, I added <policy domain=”coder” rights=”read | write” pattern=”PDF” /> just before </policymap> in /etc/ImageMagick-7/policy.xml and that makes it work again, but not sure about the security implications of that.
Note: the solution in this and other answers involves disabling safety measures that are there to fix arbitrary code execution vulnerabilities. See for instance this ghostscript-related and this ubuntu-related announcement. Only go forward with these solutions if the input to convert comes from a trusted source. I use ImageMagick in php (v.7.1) to slice PDF … Read more
You can save a large amount of space, especially if you have a large number of images.. Add the following to text.txt (format of the IPTC tags taken from here): 2#110#Credit=”My Company” 2#05#Object Name=”THE_OBJECT_NAME” 2#55#Date Created=”2011-02-03 12:45″ 2#80#By-line=”BY-LINE?” 2#110#Credit=”The CREDIT” 2#115#Source=”SOURCE” 2#116#Copyright Notice=”THE COPYRIGHT” 2#118#Contact=”THE CONTACT” 2#120#Caption=”AKA Title” Strip all existing exif data from the … Read more
I just managed to tell ImageMagick about the fonts on my OSX system like this: # Make a new directory for ImageMagick local settings and cd into it mkdir ~/.magick cd ~/.magick # Grab script to find all fonts on system and store them in a config file curl -L http://www.imagemagick.org/Usage/scripts/imagick_type_gen > type_gen # Run … Read more
My own favorites are these two: compare image1 image2 -compose src diff.png compare image1 image2 -compose src diff.pdf The only difference between the 2 commands above: the first one shows the visual difference between the two images as a PNG file, the second one as a PDF. The resulting diff file displays all pixels which … Read more
I don’t think there is anything built in to PIL that can do this. But I’ve modified your code so it will do it. It gets the border colour from the top left pixel, using getpixel, so you don’t need to pass the colour. Subtracts a scalar from the differenced image, this is a quick … Read more
if you have imagemagick access, you can do this: system(“convert big.gif -coalesce coalesce.gif”); system(“convert -size 200×100 coalesce.gif -resize 200×10 small.gif”); this is most likely possible with the imagemagick plugin if you don’t have system() access NOTE: this may create a larger filesize though a smaller dimensions image due to coalescing essentially deoptimizing the image. UPDATE: … Read more
I contend that images (files) are NOT usually stored in a database base64 encoded. Instead, they are stored in their raw binary form in a binary (blob) column, or file. Base64 is only used as a transport mechanism, not for storage. For example, you can embed a base64 encoded image into an XML document or … Read more
That’s funny you asked this, I just did this recently for my work’s site and I was thinking I should write a tutorial… Here is how to do it with PHP/Imagick, which uses ImageMagick: $usmap = ‘/path/to/blank/us-map.svg’; $im = new Imagick(); $svg = file_get_contents($usmap); /*loop to color each state as needed, something like*/ $idColorArray = … Read more
