Layers
Layers are the content containers for your BitMappery document.
Layer management is done through the options panel.
You can freely add / delete / rename and reorder layers in your document.
When in a hurry, you can instantly create a new layer by pressing Shift + Ctrl + L.
Layer types
We distinguish between three different layer types:
- Photo
- Graphic
- Text
The Photo type can only be created from imported image files. Photo content cannot be adjusted by drawing operations (as only non-destructive changes can be applied to these like effects and transformations). If you wish to change the pixel content of this layer you can do so by creating a mask or by copying a Photo layer selection onto a new layer.
The Graphic type is used for painting / brushing / copied content. Changes made here are persistent (though individual actions are recorded in state history to be undone/redone in the current session). This is the default type for any newly added layer.
The Text type can only contain text. It can be created through the "Add layer"-window or by selecting the Text tool.
Layer effects, filters and transformations
Each layer type can contain one or more effects, filters and transformations. These operations are applied non-destructively which means the source content remains unchanged. As such you can always change your mind and adjust these settings at any time. Drawing on an effected layer will consume more resources, if you are satisfied with your effects and wish to make them permanent you can commit the effects from the layer menu.
Additionally you can also specify the layers blend mode. The blend mode determines how the layer is "mixed in" above the content of the underlying layers. You can use this to adjust the way the colors of your layer interact with the colors of the underlying document content.
