Converts image data in a RasterImage based on its ICC profile and sets the output as a RasterImage.
public void ConvertImage(
RasterImage srcImage,
RasterImage dstImage
)
srcImage
A RasterImage object holding the input data. The source RasterImage provides an ICC profile that is applied for this conversion.
dstImage
A RasterImage object that will hold the converted data.
There are other conversion methods available in the LEADTOOLS Color Conversion toolkit, however, to get optimal conversion results use ConvertImage(RasterImage,RasterImage) or ConvertImage(RasterImage,RasterImage) as they rely on the embedded ICC profile of the source RasterImage. Here is a scenario where these two methods are invaluable:
srcImage and dstImage should be allocated and have the same width and height. Both images should be 24-bit.
The conversion engine should have already been started by calling Start. The input and output formats for the conversion engine should be BGR/RGB for predictable results. Other types of conversion (LAB, CMYK, etc) might have undesired results.
You can perform the conversion in-place (storing the output in the source bitmap) using ConvertImage(RasterImage).
This example loads a source file containing an embedded ICC profile. The image data will be converted using the ConvertImage(RasterImage,RasterImage) method.
