TMufasaBitmap.CopyClientToBitmap. Added a "Set Client" feature to OCRBench, so you can test on runescape. Also added TMufasaBitmap.ToTBitmap. git-svn-id: http://www.villavu.com/repositories/merlijn/mufasa@325 3f818213-9676-44b0-a9b4-5e4c4e03d09d

When splitting the shadows, having the `original' points of the chars would be very helpful when splitting!
|
|
|
|
Short description:
|
|
Merge shadow and char; (Same colour; simple)
|
|
Split with spacing of 1.
|
|
Remove character points; leaves only shadow. Voila, perfect splitting.
|
|
Splitting could go wrong for shadows of characters with two much spacing; like 'h'.
|
|
|
|
In some cases, this may `bind' characters to each other.
|
|
In this case, we need to remove the shadow and split again. After this split
|
|
we can put the shadows back in, and see to what group they belong.
|
|
|
|
We can also just split the chars, and then use their shadow.
