Bitmaps can be compressed in our SLCD based products to save Flash memory space. The disadvantage is 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 (for example cover entire screen), or are re-drawn often, compression can be disabled by using inserting the string “.unc” into the file name, e.g. “01_MyBitmap.unc.bmp”. This tells the BMPload program not to compress this file’s image. Background bitmaps for slider objects and meter objects and sliding graphics (“xio” command) need to be uncompressed as well.
