How can I balance bitmap display performance and storage use?

Compressing bitmaps be in our SLCD products allows you to save Flash memory space. The disadvantage is that compressed bitmaps display more slowly. To balance performance and Flash display storage, it is best to use the “Enable Bitmap Compression” checkbox in the BMPload application. For bitmaps that are large (i.e. cover entire screen), or are re-drawn often, disable compression by inserting the string “.unc” into the file name (e.g. “01_MyBitmap.unc.bmp”). This string tells the BMPload program not to compress this image. Background bitmaps for slider objects and meter objects and sliding graphics (“xio” command) need to be uncompressed as well. Using the strategy above should keep you application visually responsive while conserving Flash memory for future additional bitmaps.
