Revision as of 15:16, 3 January 2013
A sprite is a two-dimensional image or animation that is integrated or overlaid into a larger scene. This article shows how to overlay sprites over a map using the Nokia Map API's GFX library method.
Contents |
Introduction
The example code below will load an online icon pack image (iconPackUrl) and then use the Map API's GFX library method (gfx.BitmapImage) to pick up images out of the pack defined by a position and a size. These bitmaps will then be attached to map marker icons to be displayed onscreen.
The icon image is a free icon pack called "1945" and can be obtained in various image formats, one is located here: http://www.2dgamecreators.com/tutorials/stripanimmakerlite/1945.bmp
Note: this image is partially edited for transparency.
