1. Using ImageMagick, I'm trying to resize a JPEG picture dimensions and reduce the file size. The issue is that I don't want to loose the Image quality. I've tried the following commands : convert -resize 170x80 -resample 100x100 image1.jpg image2.jpg. => A resized picture but a bad quality As you can see a 64x64 square image was NOT produced by -resize.In fact the images were only enlarged or reduced just enough so as to best fit into the given size. Ignore Aspect Ratio ('!' flag) If you want you can force -resize to ignore the aspect ratio and distort the image so it always generates an image exactly the size specified.This is done by adding the character '!' to the size The image she's working with is 16x24 in dimension at 280 DPI. The JPEG file is about 45MB on disk. She needs to get that file down to 10MB or so, without losing image quality (if that's at all possible). So, I asked her to run this command: Code: Select all. convert -strip -quality 90 big-image.jpg new-image.jpg ImageMagick resize image without losing quality. Resizing images without losing sharpness/quality, mogrify -normalize -resize 298x397 -quality 100% *.jpg.

This smooths out the blockiness, but the file size stays pretty low. Finally, ImageMagick would remove meta data to get an even smaller file. The second way to choose a resampling filter in ImageMagick is with the -filter setting
$ mogrify -resize 100x100! ./some/path/*.png $ mogrify -resize 100x100^ -gravity center -extent 100x100 *.png Conclusion. Resizing images from the command-line is really just the tip of the iceberg. ImageMagick supports a ton of additional options that allow you to optimize images, play with the colors and even pixelate things 90. For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other. Try something like. convert -density 300 image.eps -resize 1024x1024 image.jpg. Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory. Im using Gimp to resize images. When using a high res image normally 4500 x 2994 i usually need to shrink this image to 325 x 130 pixels. As you can imagine i loose the shiny, glossy and high res quality oof the image. Ive tried to save the image as .bmp and then resize it, this has made a slight difference but not a considerable change
