ImageMagick

问题 I use ImageMagick on the Google Cloud Platform. I use rails and Google's App Engine Flexible Environment. So the problem is I want to upload an Image to process in more sizes. I use paperclip. The error is: Could not run the identify command. Please install ImageMagick. So my question is how I can solve this issue? Uploading a Image without processing works 100%. But the issue is the processing I think. So paperclip needs ImageMagick to process the images. The problem is I use App Engine

问题 I need to install ImageMagick 6.5.8 (or earlier might do), but even when I checkout an earlier commit, it installs the latest version (6.6.9-4). I did this: $ git checkout -b im-6.5.6 ff414bb (then confirmed that the working tree shows the correct version of imagemagick.rb, with @url = a .tar of version 6.5.6-5) $ brew install imagemagick (and it says Checking out tag 6.6.9-4 and then proceeds to install that version) Any help would be appreciated. Thx. 回答1: Hope you managed to find a

问题 I am using ImageMagick on Mac OS X (10.7). I installed it with the help of MacPorts . When I now enter the Terminal and write: identify image.jpg it is working perfectly fine. But now while executing it from within Java, the following exception gets thrown: org.im4java.core.CommandException: java.io.FileNotFoundException: identify I can see it's on the PATH by running: which identify with the response: /opt/local/bin/identify Now while running: echo $PATH I get the response: /opt/local/bin:

问题 I have thumbnail product images that are in different aspect ratios and sizes. This is a marketplace app so sellers will load images in various sizes. I want to resize to make them fit within the 200x200 thumbnail grid that I have. I'm on Rails 4, Paperclip 4.1, Imagemagick 6.8.9 Based on an earlier version of IM, this is the effect I want - http://www.imagemagick.org/Usage/resize/#space_fill - fill blank space to fit a 200x200 grid. See the problem with alignment on my demo site here -

问题 I tried to use apt-get install imagemagick command to install ImageMagick on my Debian Wheezy. But when I try to diff images, I get following error: root@work:/home/tests/YAML_SHOTS/en-us# convert 1.png 2.png -metric RMSE -compare 3.png convert.im6: unrecognized option `-metric' @ error/convert.c/ConvertImageCommand/2060. Secondly, I tried to install ImageMagick from binary source (described here: http://www.imagemagick.org/script/install-source.php#unix). But it does not install the convert

问题 I'm failing at translating the following PHP/ImageMagick code into Ruby RMagick (to make it more manageable for future users and to understand what it's really doing): $output = array(); $returnValue = 0; $pngFiles = $myDir->find("/.png$/i"); foreach($pngFiles as $pngFile) { $cmd = 'convert '.$pngFile->path.' -resize 1x1 -alpha on -channel o -format "%[fx:u.a]" info:' exec($cmd, $output, $returnValue); if($output[0] != 1) { logMessage("PNG file contains some alpha transparency and will not be

问题 This is my ImageMagick code which works fine on my webserver by creating new image with the file name 'coloured_font.png' in a default directory ... <?php $cmd = " -background none -pointsize 60 -font Times-Roman -fill red ". " -strokewidth 1 -stroke black label:\"google\" "; exec("convert $cmd coloured_font.png"); ?> But now I am running ImageMagick on Windows which will not create any image files in a default folder but ImageMagick applications runs fine(i have tested by creating thumbnail)

问题 I'm working on an photo upload app and need to allow users to upload raw files from cameras (these are not jpegs) and have the server automatically create a jpeg version of them. I currently have Imagemagick installed but I don't think there is a way to do it in there. Cameras come out with new raw formats all the time, so im looking for something that will be relativley up-to-date and command php exec() is an option too. Does anyone have anything to suggestion for raw conversion? 回答1:

问题 I've written a Python script that downloads and converts many images, using wget and then ImageMagick via chained subprocess calls: for img in images: convert_str = 'wget -O ./img/merchant/download.jpg %s; ' % img['url'] convert_str += 'convert ./img/merchant/download.jpg -resize 110x110 ' convert_str += ' -background white -gravity center -extent 110x110' convert_str += ' ./img/thumbnails/%s.jpg' % img['id'] subprocess.call(convert_str, shell=True) If I run the content of convert_str

问题 I lost a day trying to figure this out, at various times getting "no decode delegate for this image format" and "The specified module could not be found" errors. The information I could find on these problems was dated in terms of version numbers, and many included instructions like overwriting the ImageMagick-installed dlls from the PECL distribution or copying dlls into windows/system32; two things I didn't want to do. Environment: Windows 10 Wampserver: 3.0.0, Apache/2.4.17 (Win64) PHP/5.6
