I'm trying to generate ImageMagick images from SDL pixel data. Here's what the GIF looks like so far. (This GIF is slower than the one below on purpose.) Here's what it's supposed to look like. Notice in the above image that the pixels seem to be overlayed on top of other pixels. Here's where the GIF is actually created. void Drv...
I use the following two methods to to generate text preview image for a .ttf font file PIL method: def make_preview(text, fontfile, imagefile, fontsize=30): try: font = ImageFont.truetype(fontfile, fontsize) text_width, text_height = font.getsize(text) img = Image.new('RGBA', (text_width, text_height)) ...
Hi, How do I create gradients with ImageMagick in C++? I am trying to create a visual representation of a WAV file. I can create an Image with Magick++, draw in the waveform data and save the image as a .png file but it still looks a bit basic. I'd like to give the image background and waveform gradients but I don't know how. Are the...
Hi, I am trying to extract a range of pages from a multipage pdf file into individual jpegs using convert (Imagemagick). The extraction works fine. What I am stuck on is that if I want to extract page range 10-20, I still get out jpeg files with names page-0.jpeg to page-9.jpeg while I want them to be named page-10.jpeg to page-20.jpeg....
I have an application that allows users to upload images. The test case I use is a jpeg of 1.6MB with dimensions 3872 x 2592px. The upload script in the back-end will resize the uploaded image into 6 additional formats: square (small 75 x 75) Small Thumb (50 x 38) Thumb (100 x 76) Small (240 x 161) Medium (500 x 378) Large (1024 x 774)...
I'm using im4java to call imagemagick from a grails app. The command line I'm trying to get it to use is convert "c:\ZonesG\web-app\spresources\summarypage_images\00\09\18\myimage.jpg" -resize 100x100 "c:\ZonesG\web-app\spresources\summarypage_images\00\09\18\myimage_thumbnail100.jpg" or convert c:\ZonesG\web-app\spresources\summarypag...

I have a folder of about 20000 images, and I need to generate thumb images for them. What's the fastest way to do this job? I know I can do it using some image resizing libraries. But I am wondering maybe there's already a tool or code snippets that could do this job. ...

How can I convert 2 tiff images to PDF, I already knows how to get the image out of the DB, and I print it using echo and setting up the MIME type. But, right know I need to use a duplex printer option, so I need a way to generate a PDF from inside my PHP page, that PDF must containt both TIFF images (one per page) How can I do that? Wh...
I am interested in making a 3D pie chart dynamically on my page depending on values pulled from my database. The chart would only be updated every few days, so I don't mind a process intensive task as I could cache the image. 2D charts and pie graph libraries seem to be everywhere, but are there any libraries (server side image magic, or...
I'm using ImageMagick to render PDFs as master JPGs as an intermediate step before making thumbnail images of various sizes, and I'm getting different results when I execute the command in PHP using exec() than I get when I run it on the command line directly. This is the command I'm using: exec("/opt/local/bin/convert -geometry 1000x1...
I need to take a list of words and create a PNG file of each, with a transparent background. I’d like my script to allow for adjustable opacity of the foreground, but I can probably also do it after the fact when the images get imported into Matlab. I imagine this is doable with ImageMagick and have installed that on my Mac. If someon...
When using ImageMagick, I can set certain limits for memory usage and maximum number of threads. There are 3 ways to do this, as far as I know: use a command line options like "convert -limit memory 128mb original.jpg new.jpg" use environment variables like "MAGICK_THREAD_LIMIT=1" edit the 'policy.xml' configuration file to change the ...

I am programmatically generating several sizes of thumbnails for images. I need to preserve the color space of an image while removing all (other) EXIF information. I am using imagick on PHP 5.3, but information on how to do this with any imagemagick API would be helpful. I'm trying to prune the file size of my image thumbnails as muc...
Hey S.O. People I have just started doing some ImageMagick work. I am currently trying to convert an image from a file size that is almost square (1411 x 1486) or similar sizes to a square shape, like 1024x1024 unfortunately the resize function doesn't seem to do a resize of the canvas so i keep getting number like 1024x982. I am wonder...
I have a set of AI files that I want to scale up. The AI files have a size of 200x200, and I want to scale them up to 400x400. As Illustrator does things with vectors it's not a problem, but now I want to do this for many AI files, and wanted to do it programmatically. Imagemagick's convert is able to take an "ai" file as input, but d...
