Meta-data can be important if you want to annotate such information onto the Profiles, time delays, as well as the save compression and depth. That in things such as labels, comments, color Generally it is not just the images size that needs to be preserved, but all This can be done by converting thatĮxisting image into the canvas needed, but preserving the image's original One most basic techniques, when using ImageMagick, is to generate a canvas of Here we grab a rose color from the built-in " rose:" image.Ĭonvert rose: -crop 1x1+40+30 +repage -scale 100x100\! canvas_rose_red.gif We use " -scale" for a simple and fast resizing of the single pixel. You can even grab a single pixel from an existing image, and expand it to theĬanvas size you want. If you have already created a canvas, but need one in a different color youĬan replace that color using the " -opaque" operator.Ĭonvert canvas_khaki.gif -fill tomato -opaque khaki canvas_tomato.gif Not get the size requested if it isn't square. The '!' is needed as the numbers are resize values, otherwise you Technique means you can specify a 'xc' canvas image of a specific size andĬolor as a single 'input image' argument to many ImageMagick Scripts.Ĭonvert 'xc:Salmon' canvas_salmon.gif We can just specify a solid color canvas image as a single argument. For example here is an image using the X window color ofĬonvert -size 100x100 xc:wheat canvas_wheat.gif More commonly a short hand (and more traditional) format of here I generate a ' khaki' colors canvas.Ĭonvert -size 100x100 canvas:khaki canvas_khaki.gif Is specified a ' white' canvas is generated.įor example. " canvas:" to generate an canvas of the color given. (defaulting to " 1x1" is no size given), and then use Generating a canvas of a specific color and size is very simple to do. Methods that can be used to generate a whole range of canvas images.
