3.5 Storing Images in Flash Memory
LightCrafter 4500 allows images to be compressed and stored into the 32-MB flash memory. For most
efficient storage and compression of images, stored images are packed into groups of 24-bit RGB bitmap
images and decompressed on the fly while loaded from flash memory. To ease the packing of any bit
width images, the LightCrafter 4500 GUI offers the Create Images subtab, see Figure 3-14. To create a
24-bit image from different multiple bit depth images, perform the following steps:
1. Select the Image / Firmware tab and the Create Images subtab.
2. Select a bitmap file with 912 columns by 1140 rows by clicking the ... button next to Input bmp file
3. Select Output bitmap file by clicking the ... button next to Output bmp file
4. For an input file, add the individual bit-planes by repeating the following process:
(a) Set the bit depth and the bit field position with the Bit depth and the At bit position pulldown
selectors, respectively.
(b) Click the Add to Output File button. The current image is bit weighted and saved into the 24-bit
image of the output file.
