Adjust Image Size

When you About Publishing the content, the images will be sized based on added attributes and values. You can Preview a Topic to see what the sizing will look like in your different outputs.

Typically, you should only set the width or contentwidth of an image. The depth or contentdepth (height) will automatically be calculated, to keep the image dimensions as the original image file. If you set both width and depth the smallest value of the two is used, and the image is scaled according to that.

There are several other attributes to control width and height. If you want to learn more about the possibilities, see DocBook image sizing reference.

For HTML5 output, you can combine the features Thumbnail Images and Lightbox for Images to get small image versions that are enlarged when selected.
