问题 This question has already been asked here, but since I have many more details to provide, I think it is best to start with a new question. I have trouble linking the ImageMagick lib files in my program that uses the Visual Studio MSVC 2015 compiler. Here are the steps I have followed: I have compiled the static MT runtimes by using the "configure.exe" utility and built in Visual Studio the solution it generated, "VisualStaticMT.sln". This creates lib files such as "CORE_RL_Magick++_.lib" in C

问题 I'm trying to call an ImageMagick command from Python 2.7 using subprocess.call. My problem is that the argument parser in subprocess puts a double quotation mark around every argument, and ImageMagick seems to have a problem with quotes around non-file arguments. What I'd like is something like this "imagemagick.exe" "im1.png" "im2.png" -alpha off ( ... ) -composite "im3.png" So far I couldn't find a way to do it with subprocess, other than manually constructing the string with ugly + " " +

问题 Is there a way to move all gray colors of a CMYK image (e.g. a CMYK .tiff) into the black (K) plate with ImageMagick? (In Adobe Acrobat Pro, this functionality is labeled: "Promote grays to CMYK black") Here's an image to experiment with: You can view an example of this process on Wikipedia. 回答1: Also not a full answer as such, but hopefully useful towards producing one - by Kurt, myself or others. I looked at the Photoshop method of GCR and am adding the characteristic curves that Adobe seem

问题 I have a jpeg containing alpha blended text. Knowing the font and size, I deduced a png file representing the text Using ImageMagick, can I get an approximation of the original picture? 回答1: Albert Myšák has the proper technique here, since one knows the exact alpha channel values for the text and the equation that describes how the alpha channel is blended with the image. Kudos! My earlier methods are better suited to when one only knows the positions of the text pixels in the image, so that

问题 I am trying to implement a functionality using Magick.NET in C#. Previously I was using:- // Convert to a png. Process p = new Process(); p.StartInfo.FileName = @"C:\Program Files\ImageMagick-6.2.8-Q16\convert.exe"; p.StartInfo.Arguments = "-scale 60% \"" + svg + "\" \"" + png + "\""; p.StartInfo.CreateNoWindow = true; p.Start(); p.WaitForExit(); TransmitFile(context, png); I want to move away from having to store convert.exe on the server.....Now I want to use something that will be in code
