Methods
Name | Description | |
---|---|---|

Adjusts an image's brightness, contrast and gamma as well as it may
optionally invert the image within a single operation.
|

on a 1-, 4- or 8-bit palletized image.
|
![]() | Clone |

|
![]() | CloneMetadataFrom | Overloaded. |
![]() | Composite |
This method composite a transparent foreground image against a single background color or
against a background image.

|
![]() | ConvertColorDepth |
Converts this FreeImageBitmap into a different color depth.
