这个教程好，还有，一定要新建一个图层来KNOCKOUT，CANVUS是不给KNOCK的
KnockOut 2 Application Notes
General
- You may experience some color shifting when an image/layer is loaded into KnockOut 2. The layer is applied back to the host application correctly.
- Corel PHOTO-PAINT 8 - When you use Corel PHOTO-PAINT 8 as a host, images brought into KnockOut experience a large color shift. This is due to the fact that Corel PHOTO-PAINT 8 gives KnockOut the RGB color information in a different order than KnockOut is expecting, thus creating a discrepancy in the display of the image. The image is applied back to Corel PHOTO-PAINT 8 correctly.
Memory
- 128 MB of RAM is the minimum requirement to run the application. However, for larger images make sure you have a total of at least 3 times the image size in available memory (either real or virtual memory).
Load Working Layer
- To load a working layer, a valid layer (not the background) must be selected. If the image you want to knock out is part of the background you must either copy the image to a valid layer or duplicate the background to create a valid layer.
- Painter - To avoid data corruption in Painter, layers must first be dropped to the canvas and then copied and pasted to create a new a layer prior to loading the working layer in KnockOut
- Layer transparency should not be locked. Because KnockOut works with transparency information on a layer, locking the layer transparency could cause undesirable results.
Load Saved Project
- Before loading a saved project you must create and select and empty layer. Make sure that this empty layer is large enough to accommodate the image to be knocked out. If the layer is not big enough, the image will be cropped.
- When loading a saved project, ensure that the current project is in the same color mode as the saved project being loaded. If they are not, then image corruption will occur when returning to host application. For example, if your current project is in CMYK, and saved project is in RGB, then the image will be corrupted when applied back to the host application.
Applying image to host application
- The plug-in will not automatically create an alpha channel. When the image is brought back to the host, you can create a mask channel containing the transparency information of the image and shadow combined. For instructions on how to create this channel, please refer to the KnockOut documentation.
