• Effects filters (such as blur and edge detect) • Channel and color operations (such as add, composite and decompose) • Plug-ins that allowed for the easy addition of new file formats and new effect before Layers, when floating selections and channel operations were the only tools for working with composite image information. Making selections within the float was used as a quick, but rather ineffective the composite image. If the Sample Merged option is unchecked, the wand will only react to the color in the active layer when it creates a selection. If it is checked it will react to the composite color

Image D Now we are ready to make our final image. Execute "Filters->Channel Ops- >Composite." Our goal is to composite our copy of Image A with Image D using Image B as our mask. The mask will take the pixels from Image A where Image B is black and take pixels from Image D where Image B is white. The composite window will have pull- down menus for your choices. Look at the titlebars to find which actual images

If this is the case, the colors present in the layer will be different from the colors in the composite image. If the “Sample Merged” option is unchecked, the wand will only react to the color in the the active layer when it creates a selection. If it is checked it will react to the composite color of all visible layers. For further information, see the glossary entry Sample Merged.
