ApplyPaletteCommandSelectPreferredPixelFormat Method

protected override PixelFormat SelectPreferredPixelFormat(
	AtalaImage sourceImage,
	PixelFormat sourceFormat,
	PixelFormat[] formats
)

Protected Overrides Function SelectPreferredPixelFormat ( 
	sourceImage As AtalaImage,
	sourceFormat As PixelFormat,
	formats As PixelFormat()
) As PixelFormat

Parameters

sourceImage

Type: Atalasoft.ImagingAtalaImage
The original source image.

sourceFormat

Type: Atalasoft.ImagingPixelFormat
The original image's pixel format.

formats

Type: Atalasoft.ImagingPixelFormat
An array of pixel formats supported by this command.

Return Value

The default implementation returns the sourceFormat value.

In theory, a command should only ever return pixel format that it has direct support for. Unfortunately, many older commands advertised that they supported pixel formats that were not native to the command. To maintain compatibility with older versions of dotImage, this method allows a command to select a new pixel format for itself, without being bound to the ApplyToAnyPixelFormat property.
