![]() $ convert -annotate +startx+starty "annotation" SrcImage.ext DstImage.ext The basic command-line syntax to -annotate an image using ImageMagick is: The blog uses -annotate as the vehicle for explaining how to put text in images, and then I describe how I used -draw to put the embossed watermark text on the maps at the top of each page, and -caption label -label for setting text in pre-defined geometries. ![]() The general options for setting fonts, colors and postions are similar. Which function to use depends on how much and what type of control you want to have over the text that is written. The ImageMagick functions -annotate, -draw, -caption and -label can all be used for writing text to images. ![]() If this happens, try to use the option +repage, and ImageMagick adjusts the canvas to fit the layer. A canvas can contain more than one layer, and the positions you are setting the text at might be in the canvas but outside the layer. If ImageMagick does not put the text as you expected (or not text at all), the chance is that your layer is not filling up the canvas. The previous post is an introduction to ImageMagick. This post only covers how to use ImageImagick for putting text in images, and to create image compositions. This can not be done manually, and I chose to use ImageMagick. I also wanted to create animations from time-series of maps, and put both a caption, a time line and a clock in the image. This post is about putting a caption, label, watermark or other text directly in an image for web publishing.
