The FreeImageBitmap type exposes the following members.
Constructors
Name | Description | |
---|---|---|
FreeImageBitmap | Overloaded. |
Methods
Name | Description | |
---|---|---|
AdjustBrightness |
Adjusts the brightness of a 8-, 24- or 32-bit image by a certain amount.
| |
AdjustColors |
Adjusts an image's brightness, contrast and gamma as well as it may
optionally invert the image within a single operation.
| |
AdjustContrast |
Adjusts the contrast of a 8-, 24- or 32-bit image by a certain amount.
| |
AdjustCurve |
Perfoms an histogram transformation on a 8-, 24- or 32-bit image.
| |
AdjustGamma |
Performs gamma correction on a 8-, 24- or 32-bit image.
| |
ApplyColorMapping |
Applies color mapping for one or several colors on a 1-, 4- or 8-bit
palletized or a 16-, 24- or 32-bit high color image.
| |
ApplyPaletteIndexMapping |
Applies palette index mapping for one or several indices
on a 1-, 4- or 8-bit palletized image.
| |
Clone |
Creates a deep copy of this FreeImageBitmap.
| |
CloneMetadataFrom | Overloaded. | |
Composite |
This method composite a transparent foreground image against a single background color or
against a background image.
In case useBitmapBackground is false and applicationBackground
and bitmapBackGround
are null, a checkerboard will be used as background.
| |
ConvertColorDepth |
Converts this FreeImageBitmap into a different color depth.
The parameter bpp specifies color depth, greyscale conversion
and palette reorder.
Adding the FICD_FORCE_GREYSCALE flag will first perform a convesion to greyscale. This can be done with any target color depth. Adding the FICD_REORDER_PALETTE flag will allow the algorithm to reorder the palette. This operation will not be performed to non-greyscale images to prevent data loss by mistake. | |
ConvertType |
Converts this FreeImageBitmapFREE_IMAGE_TYPE to
type initializing a new instance.
In case source and destination type are the same, the operation fails.
An error message can be catched using the 'Message' event.
