Art File Formats (Mobile)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Art files for skins may be either bitmap (.bmp) or GIF (.gif) images. JPEG (.jpg) and PNG (.png) images are also supported. Do not include any spaces or commas in your art file name.
If you are synchronizing files to a portable device, be sure that the synchronization does not change the file name extension or convert the image files to another format.
Many drawing programs can be used to create bitmaps and GIF files, or to convert art in other formats to bitmaps or GIF files. For example, you can use Microsoft Paint, which comes with Microsoft Windows, for simple drawings.
You will want to trim the blank areas of your images around the edges to reduce file size. You can use the offsets in the Bitmaps section to compensate for removing blank spaces on the left and top sides. You can also trim the bottom and right blank edges of the images because they are not needed for measurements. The only files you should not trim are the Background, SeekThumb, and VolumeThumb images.
