CropAlpha does resize and therefor blur images.
How do i stop CropAlpha from resizing the cropped bitmap (making it bigger instead of shrinking the iebitmap canvas to the actual pixel area without stretching the data,
as my intention is to remove transparency and not to resize the image into a big blury state.
I can't even think of a use case where i wanted the pixel data to get stretched after using CropAlpha, as the result looks worse aways.
There seem to be different ways to crop a iebitmap or imagelayer but some resize and some aren't for both or have a different intention.
Whats the use case of these crop functions and is there a function that just removes the transparency, leaving the pixel data the real size?
Or getting the crop position and extracting the real size, so i would be able to do a downsizing after CropAlpha? |

CropAlpha work on the bitmap directly, so the layer object does not update, so you do need to use a method to restore the size to 1:1.

Well, seems that TIEImageLayer.RestoreSize does the trick. |

The right bell has alpha.
The left huge bell is after CropAlpha or CropTransparentBorder.
The bottom bell is like i wanted it to be... with alpha removed and no blowing up.
Also the blown up bell got the border area cropped do to the resizing algorithm i guess.
