Restrictions in BMP to RLE Conversion
The dimensions of the image should be within that supported by the device. Otherwise there is no restriction on the BMP; any BMP can be converted to RLE, but possibly with some loss according to the limits of the RLE format and the device. Two things to keep in mind when creating a BMP for overlay are transparency and number of unique colors.

Note that a checksum is not generated by the makeover tool; the user will need to generate a checksum required by the target product.
Command line parameters
-inbmp <filename>
Specify the filename of an image file to load. Supported file formats include BMP, PNG, JPEG and TIFF. If the image contains too many unique colors, it will be quantized down to eight colors.
-transparency <rule>
Specify the transparency rule to apply when reading the file given by -inbmp. The transparency rule defines how to generate the image transparency (alpha plane).
The rules are:
- fromfile; Use the transparency information from the input file unaltered. If the input file had no transparency data then the whole image will be opaque. This is the default.
- none; The output image will be completely opaque. If the input file had any transparency information it will be ignored.
- brightest; Make the brightest color (after quantization) transparent, all other colors opaque. If the input file had any transparency information it will be ignored.
- white; Make any pixels that were exactly white in the original input image transparent, all others opaque. If the input file had any transparency information it will be ignored.
- first; Make upper left corner pixel transparent as well as any other pixels of the same color, all others opaque. If the input file had any transparency information it will be ignored.
