Hi Freinds,


Is there any method to use the RenderTargetBitmap to render  the image in CYMK format. The source is a DrawingImage. This collects the image from a DrawingGroup. The final Drawing need to save as Image File of CYMK format. Is there any Codecs source available to use in this conversion pls.

Thanks & Regards,

推荐答案

您应该可以:

RenderTargetBitmap renderTarget =新的RenderTargetBitmap(resX，resY，dpiX，dpiY， PixelFormats . Cmyk32 );

如果以这种方式生成它，它应该在内部将数据另存为CMYK.

如果您随后使用

You should be able to do:

RenderTargetBitmap renderTarget = new RenderTargetBitmap(resX, resY, dpiX, dpiY, PixelFormats. Cmyk32 );

If you generate it this way, it should save the data, internally, as CMYK.

If you then save using TiffBitmapEncoder specifying BitmapCreateOptions.PreservePixelFormat, it should save it as a CMYK TIFF file.
