"plug-in-gap-modify" Modify Frames Start from Menu: /Video/Frames Modify The GIMP-GAP plug-in 'Frames Modify' provides the feature to perform functions on one ore more selected layer(s) in all frames of the selected frame range. Layer Selection: The layers can be selected by (parts of) their name, or by their layerstack numbers. The selection is contolled via the LayerPattern entry, the case sensitivity toggle and the radio buttons. The toggle button "Invert Layer Selection" inverts the selection. Some of the available funtions affect the image and do not allow layer selection. The Function menu: Layer Attributes "Set Layer(s) visible", "Set Layer(s) invisible", "Set Layer(s) linked", "Set Layer(s) unlinked), Layer Modes "Set Layer(s) mode: Normal", "Set Layer(s) mode: Dissolve", "Set Layer(s) mode: Multiply", "Set Layer(s) mode: Divide", "Set Layer(s) mode: Screen", "Set Layer(s) mode: Overlay", "Set Layer(s) mode: Difference", "Set Layer(s) mode: Addition", "Set Layer(s) mode: Subtract", "Set Layer(s) mode: Darken only", "Set Layer(s) mode: Lighten only", "Set Layer(s) mode: Dodge", "Set Layer(s) mode: Burn", "Set Layer(s) mode: Hardlight", "Set Layer(s) mode: Softlight", "Set Layer(s) mode: Color erase", "Set Layer(s) mode: Grain extract", "Set Layer(s) mode: Grain merge", "Set Layer(s) mode: Hue", "Set Layer(s) mode: Saturation", "Set Layer(s) mode: Color", "Set Layer(s) mode: Value", Layer Stackposition "Raise Layer(s)", "Lower Layer(s)", Merge Layers "Merge Layer(s) expand as necessary", "Merge Layer(s) clipped to image", "Merge Layer(s) clipped to bg-layer", Selection "Replace selection (source is the active frame)", "Add selection (source is the active frame)", "Subtract selection (source is the active frame)", "Intersect selection (source is the active frame)", "Selection none", "Selection all", "Selection invert", "Selection from alpha channel (individual per frame)", "Save selection to channel (individual per frame)", "Load selection from channel (individual per frame)", "Delete channel (by name)" Layer Mask "Add white layermask (opaque)", "Add black layermask (transparent)", "Add layermask from alpha", "Add layermask transfer from alpha", "Add layermask from selection", "Add layermask from bw copy", "Invert existing layermask", "Apply filter on layermask", "Delete layermask", "Apply layermask" "Copy layermask from layer above" "Copy layermask from layer below" "Apply filter on Layer(s)", "Duplicate Layer(s)", "Delete Layer(s)", "Rename Layer(s)", "Add alpha channel", The Functions "Replace Selection", "Add Selection", "Subtract Selection", "Intersect Selection", take the Selection from the initial (invoking) frame and combines it with existing selections in all the other handled frames. The Functions "Copy layermask from layer above" "Copy layermask from layer below" create Layermasks in the selected layer(s) in all handled frames by copying from the neigbour layer above (or below) the specified layer(s). If there is no such neigbour layer, a black (full transparent) layermask will be created for the slected layer(s). If the neigbour layer has no layermask, the mask will be create as black and white copy of the neigbour layer. The layermask is placed at the center of the selected (destination) layer. If the neigbour layer is smaller than the selected layer, the uncovered border of the created layermask is created full transparent. The Functions: "Duplicate Layer(s)" "Rename Layer(s)" "Save Selection to Channel" "Load Selection from Channel" "Delete Channel (by Name)" require a Name in the Entry field "New Layer Name" (the name of this entry changes to "New Channel Name" when dealing with channels) The function "Apply filter on Layer(s)" brings up a dialog window when started via pressing the OK button. this dialog is similar to the PDB-Browser, where you can select one of the available filters. If you use the PDB-Browser's button "Apply Varying", the filterparameters will slightly change in each handled frame from start to end. - If there is more than one selected layer in a frame each of the selected layers within the same frame will be processed with the same filter parameter values. (for more information see chapter 'Animated calls of Plug-In Filters' below) The function "Apply filter on layermask" works with same additional dialog steps as described for function "Apply filter on Layer(s)", but applies the selected filter to the layermask instead of the layer itself. If the first selected layer in the first handled frame image has no layermask, this function will terminate with an appropriate error message. If the filter shall be applied with varying values, it is also required that the first selected layer of the last handled frame image has a layermask. If the selected layer(s) of the frame images of the selected frame range between first and last handled frame have no layermask, the filter processing is skipped on those layers, but processing will continue. It is a good idea to use the same layerstack structure in all your frames. Another hint is that you assign useful names to your layers. that should be done consequent for all frames.
