* This example demonstrates how the color palette of an image can be modified
|
|
* during run-time of the program to exchange colors.
|
|
* This example uses a BMP1 image (one-bit BMP) and which only has a palette
|
|
* size of two.
|
|
* Note that although the demo shows multiple images with different colors at
|
|
* the same time there's still just one copy of the image in memory at all times.
