Perhaps you have a height and width you are aiming for, but want to preserve the aspect ratio. The commands animate, display, and import require an X server (the X Window System) to function. The easiest way to convert images to grayscale ( graylevel ) is by using imagemagick the image manipulation programs suite. This will scale all of your images to a width of 960 pixels, the height will be scaled accordingly, preserving the aspect ratio. The more obvious and common way to change the size of an image is to resize or scale an image. In version 7 of ImageMagick, these tools can be accessed with the magick command, for example magick compare.Also, the script interpreter can be accessed with magick-script. Perhaps the height isn’t as important as the width. png files in your directory to a size of 960 pixels by 528 pixels. Place all the images you want to scale in a directory and navigate to that location via command line. You’re in luck! With the ImageMagick -resize option, you can quickly and easily batch scale those images to a manageable size. You can also append to the dimensions to tell ImageMagick that you’d like to resize the image to fill the dimensions, potentially overlapping on one side. What it will do is resize the image to fit within those dimensions. The last thing you want to do is resize them manually. convert original.png -resize 100x100 new.png This won’t actually resize the image to the exact dimensions specified. Unfortunately, this gives you a Pictures directory filled with massive images not optimized for uploading to, and displaying on, a web page. My initial attempt looks like: convert -background none inner.png circle.png -layers flatten -resize 64圆4 output.png. I'd like to overlay these two images, so that they appear centered and shrink the image size down to say 64圆4. Creating text labels, or adding text to images is probably one of the most basic and common operations for which ImageMagick is used.

Let’s say you’re writing a series of Blender tutorials and you’re using PrintScreen to grab screen shots. Given these two images of size 512x512 with transparent background: circle.png.
