- To combine two images with a fixed opacity, use the AlphaBlendCommand.
- To combine two images with a feather, use the Leadtools.ImageProcessing.Effects.FeatherAlphaBlendCommand.
- The TextureAlphaBlendCommand does the two operations; first it combines the two images with feathering using the fade mask image, then combines the result with the destination image with a fixed opacity.
- To create an image that contains a fade mask, use FadedMaskCommand.
- This command can also underlay the fade mask image with the underlay image before using it in the feather combine operation.
- This command also combines the fade mask image with the underlay image so that it appears to be an underlying texture for the fade mask image.
- The following is an example for the resulted image using this commands with the following characteristics:
- The source image is a red image.
- The destination image is a white image.
- The opacity is set to 255.
- The right image is the result of applying the method without texture image.
- The left image is the result of applying the method with texture image.
- This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
- This command does not support signed data images.
- This command does not support 32-bit grayscale images.
