=== Keyboard bitmaps === | |||
ScummVM's image manager can only decode 24-bit BMP images, so make sure you save your images in this format. You need to reserve a particular colour value to be used for transparency. By default the colour used for transparency is set to be #FF00FF, but if you want to use a different colour this can be specified in the configuration file. | |||
=== XML configuration file === | |||
The first step in creating the XML configuration file is to create the HTML imagemap data. The easiest way to do this is by using an standard image map creation tool such as GIMP's Image Map plugin (find it under Filters -> Web -> Image Map...). | |||
