7. The Menus / 7.8 The Effects Menu
Emboss calculates a height map for the active image and lightens this height map afterwards.
The subdialog Emboss controls the kind of lighting. Light is the position of the light source. Border Shape defines the width and shape of an edge in this height map. The curve field is used for the shape, Width setups the width and Mode controls the way, how this edges are calculated. You can choose between Unsharp and Shade. Unsharp creates soft and kind of flowing edges, Shade creates hard, exactly defined edges. Intensity is the strength of the light. The smaller this value the lower is the difference between light and shadow.
The subdialog Pattern setups, how to calculate the height map. There are four modes:
- Create From Mask
The mask is used as height map. The image parts, that are protected by the mask, lie lower than parts, that are not protected.
- Create From Image Intensity
The brightness of a pixel is used as its height.
- Use Pattern
The color field beneath is used for filling the height map. This way it is easy to map an image with a pattern like a paper structure.
- Create Lines
PhotoLine is drawing lines with a given Width, Length and Direction in the height map.
