ImageMagick

问题 How do I pass image filepaths to convert.exe, given I know all the file paths? ImageMagick is NOT installed, but just in my project folder. I don't think I'm supposed to pass the image filepaths through a cmd prompt. Here is my current attempt. I get no errors from it -- but a cmd prompt pops up quickly and disappears quickly -- I've printed the screen when it's up and it's saying something about userparams... which apparently has to do with ImageMagick somehow. When I run the same command

问题 I would like to install the 8-bit version of imagemagick using homebrew, as the performance is a little better and the RGB values outputted with the 8 bit version are better suited to my uses. How would I got about doing this? 回答1: I think brew install imagemagick --with-quantum-depth-8 should do the trick. 来源： https://stackoverflow.com/questions/11923126/homebrew-install-imagemagick-8-bit-version

问题 I have four separate images - 2-projected.tif, 3-projected.tif, 4-projected.tif and 5-projected.tif. These are four Landsat images. Image 2-projected.tif corresponds to blue channel, image 3-projected.tif - to green channel, image 4-projected.tif - to red channel, and 5-projected.tif - to infrared. Now I want to create NDVI image. To do this, I first create a combined RGB image, using ImageMagic: $ convert 4-projected.tif 3-projected.tif 2-projected.tif -combine RGB.tif So far, so good. And

问题 I'm using magick++ library to manage images. I want to distribute my algorithm using openMPI, is it possible to send objects? for example in my code I have Image image(imgName); int w = image.columns(); int h = image.rows(); PixelPacket *pixels = image.getPixels(0, 0, w, h); Can I send pixels with MPI_Send or Scatter of whatever? if yes with which datatype? 回答1: In general, unless you have a special library that's doing packing for you, it's never possible to send a specialized object in MPI.

问题 I'm trying to get following ImageMagick command working with the Java ProcessBuilder: convert.exe image.png `( `+clone -alpha extract mask.png -compose Darken -composite `) -compose CopyOpacity -composite out.png The file paths (source image, mask image and destination image) are configurable. If I enter the command in PowerShell or Windwos Cmd it is working as expected. When I'm trying to execute the same command via Java ProcessBuilder, it fails. Here is my last code: File srcFile = new
