Canvas Layers

From PanelForge 3 Documentation

This page was made for PanelForge v1. Some details may be incomplete or have changed when referring to PanelForge v2.

The 'Canvas Layers' palette provides the functionality to organise and adjust the image layers which are composited together to form the current Panel's Canvas.

More information about the 'Layer' element of a Panel's Canvas can be found in the Canvas documentation.


Layer List

The main central area of the palette is the list of the layers contained in the current panel's canvas. These layers are ordered with the uppermost layer first down to the lower most layer last.

Each layer entry in the list comprises of a Visibility toggle, Lock toggle, Preview Image Thumbnail, Layer label text and Layer opacity text.

Clicking the Layer Visibility Toggle 'eye icon' toggle will change the visibility of the corresponding layer. Clicking the Layer Lock Toggle 'padlock icon' toggle will lock the layer from being editable with the Canvas Tools, the Stage Layer is always locked. The Layer Label Text of locked layers will also be shown in italics.

Double clicking the Layer Label Text will allow the corresponding layer to be renamed using the displayed text edit field.

The Layer Primary Selection highlighted in light grey will be editable with the Canvas Tools. This primary selected Layer can be selected by clicking the mouse cursor on the corresponding Layer in this list.

Multiple Layer Secondary Selections highlighted in medium grey can also be selected in this list. Selection is performed using the shift and control key modifiers and clicking the mouse cursor on a Layer in the list.

Layers can be reordered in the list resulting in the Canvas layers being composited in a different order. Selected layers can reordered by being dragged with the mouse cursor to a different location in the list.

In addition layers can be dragged to other Panels displayed in the Panel Timeline and Panel Thumbnails palettes to copy the layer to the other Panel Canvas.

It is also possible to drag and drop layers to the Assets palette, the layer will be added to the corresponding place in the asset library where dropped as a PNG image file with alpha transparency.

Stage Layer

All Panels have a special layer named 'Stage', this layer shows the contents of the 3D Stage through the 'Panel Camera' at the last edited state.

The 'Stage' layer cannot be deleted and is always locked from being edited with Canvas Workspace. Although this layer can be reordered, hidden, duplicated and have its opacity adjusted.
