I need my class to do this... 1) I create a new instance of my class and I pass in either a URL of a photo, or the path to a local photo being uploaded using POST form. 2) I then need to take the main image and check it's dimensions, if it is wider the 800 pixels, I need to resize it down, if it is not

问题 I'm having a few problems with a paperclip custom processor. At the command line this line : $ convert cats.jpg -thumbnail 300x400 -bordercolor white -background black +polaroid cats.png Successfully converts this : https://dl.dropboxusercontent.com/u/4233433/cats.jpg Into this : https://dl.dropboxusercontent.com/u/4233433/cats.png i.e a JPEG converted into a PNG with a transparent background. Which is exactly what I am trying to achieve. However when I attempt to do this within Rails (4.0.1)

问题 I want to capture a screenshot of an application's window from a Python script using ImageMagick, as I would with ImageMagick's "import" command from a shell. An API call or a system call from Python (as in "subprocess.Popen(["import"...") will suffice, but I don't want to create a file on the hard drive. My OS is Linux. 回答1: Execute the command: import png:- This will cause import to output to stdout. You can also change png to one of the type tags shown here. 来源： https://stackoverflow.com

问题 I am working on a PowerShell script using Image Magick's montage function. My script works until the source files (.jpgs) volume increases to an ambiguous number of files. Once there are 'too many' files, the script fails due to 'Program 'montage.exe' failed to run: The filename or extension is too long' . It was suggested on the Image Magick forum (link @ bottom) to have PowerShell read from a text doc instead to reduce the length using the '@' operator. The code now looks like: montage

问题 It's driving me insane.. Just searched for hours to find a solution. But nothing really found. So hopefully anyone can help me. I'm trying to create an customized image on the fly. I use this to create the images: https://github.com/Treinetic/ImageArtist Everything works fine except the font. This is the snippet from the class: $im = new \Imagick(); $background = new \ImagickPixel('none'); $im->setBackgroundColor($background); $im->setFont($font->getPath()); $im->setPointSize($writer->getSize
