Libvips is a standard part of most linuxes, it's in homebrew and macports, and there are 64-bit windows binaries on the vips website. So on this test, libvips is 7x faster and uses 15x less memory than graphicsmagick. Generate JPG and WEBP Images and Thumbnails in predefined sizes. GraphicsMagick is a little faster, I see: $ /usr/bin/time -l gm convert test.tif -resize 128x128 small.png With convert I see: $ /usr/bin/time -l convert test.tif -resize 128x128 small.pngĪgain, fastest of three runs, 4.87s real time, 1.4gb memory. To process large numbers of files at once, we recommend to use a file list. That's 0.54s real time, 77MB of peak memory. I ran three times and picked the fastest, so that should just be a test of vipsthumbnail and not my disk system. With vipsthumbnail, the image shrinker that comes with vips, I see: $ /usr/bin/time -l vipsthumbnail test.tif -s 128x128 -o small.png 3) I then need to repeat step 2 but this time resize to 125 x 125. 2) I need copy & past the images to a new folder, where they will be resized to 250 x 250. The execution of this CmdLet creates a new file named 'OriginalNameresized' and maintains the original: file extension.PARAMETER Width: The new width of the image. So that's a 13000 x 10000 3-band, 8 bit uncompressed TIFF. Below I have listed the basic steps/needs of the script: 1) The images are located in a folder & are all (or should be) 500 x 500. Resize an image.DESCRIPTION: Resize an image based on a new given height or width or a single dimension and a maintain ratio flag. I timed it on this machine (imac with ImageMagick 6.9.6-3 Q16, gm 1.3.25, vips 8.4.2): $ vips black test.tif 13000 10000 -bands 3 With Image Resizer enabled, resizing images is only a few clicks away. It's got a fancy threaded IO system too, so performance is good and memory use is low. ImageMagick is a collection of command-line tools that can be used to modify and manipulate images. Step 2: Resize Images in File Explorer or Desktop. It's a streaming image processing library, so it's able to read the input, process, and write the output as a single pipeline, with no separate loading phase and no temporary files.
