The FreeImageBitmap type exposes the following members.
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.

may adjusts brightness and contrast, correct gamma and invert the image with a
single call to AdjustCurve().
|
| GetBounds |
Gets the bounds of this FreeImageBitmap in the specified unit.
|
| GetChannel |
Retrieves the red, green, blue or alpha channel of a 24- or 32-bit image.
|
| GetColorConvertedInstance |
Converts this FreeImageBitmap into a different color depth initializing
a new instance.
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. |
| GetComplexChannel |
Retrieves the real part, imaginary part, magnitude or phase of a complex image.
|
| GetEnlargedInstance | Overloaded. |
| GetHashCode |
Returns a hash code for this FreeImageBitmap structure.
(Overrides Object..::.GetHashCode()()().) |
| GetHbitmap | Overloaded. |
| GetHbitmapForDevice |
Creates a GDI bitmap object from this FreeImageBitmap with the same
color depth as the primary device.
|
| GetHicon |
Returns the handle to an icon.
|
| GetHistogram |
Computes the image histogram.
|
| GetPixel |
Gets the Color of the specified pixel in this FreeImageBitmap.
|
| GetPixelFormatSize |
Returns the color depth, in number of bits per pixel,
of the specified pixel format.
|
| GetPropertyItem |
Gets the specified property item from this FreeImageBitmap.
|
| GetQuantizedInstance | Overloaded. |

| GetScaledInstance | Overloaded. |
| GetScanline | Overloaded. |
| GetScanlinePointer |
Returns a pointer to the specified scanline.
Due to FreeImage bitmaps are bottum up,
scanline 0 is the most bottom line of the image.
|
| GetScanlines |
Returns a list of structures, representing the scanlines of this FreeImageBitmap.
Due to FreeImage bitmaps are bottum up, scanline 0 is the
bottom-most line of the image.
Each color depth has a different representing structure due to different memory layouts.
|
| GetThumbnailImage | Overloaded. |
| GetTypeConvertedInstance |
Converts this FreeImageBitmapFreeImageBitmap to type.
