The Drawing Emboss Effect lets you use your 'most recent' drawing as the color source with an added emboss.|
The Drawing Emboss Effect is identical to the Drawing Effect with the addition of an embossing effect. The Emboss Effect is similar to embossing paper, where an object is pressed into paper to leave an impression of the objects surface.
Embossing is similar to an Edge Detection, but instead of being two color like Edge Detection, Emboss is textured and can also be pseudo-colored.
Emboss outputs either a monochrome result or a pseudo-color result that is based on the strength of the embossing at any given point
If you enable the Fit To Brush Option you will paint with the Current Embossed Drawing sized to your brush.
|ReminderYou might want to also watch the Pena Tutorial #7 - Using the 'Drawing' Texture video tutorial.|
Under normal use, each time you stop painting on the Canvas (eg., lift your finger) the current Canvas is stored in a special texture called the Drawing Texture.
You can change this behavior using the Drawing Control icon on the Control Pane. You can turn off the automatic saving of the Canvas into the Drawing Texture, and instead specify manually when you want the Drawing Texture updated.
Leaving Drawing on automatic update allows you to paint with 'feedback'. Each time you start painting, what you painted last will be used as input to what you are painting now.
Putting Drawing on manual update lets you treat the last Canvas stored in the Drawing Texture as a more permanent texture, not changing each time you paint.
Also keep in mind that unlike other Textures, which automatically orient to the device orientation, the Drawing Texture, because it is a copy of the Canvas, does not auto-orient, but stays in the original orientation it was created in.
The Drawing Emboss Effect has the following Options Pane:|
|Emboss Strength:||This controls the height of the emboss effect. Smaller values produce a tighter emboss, larger values create a deeper emboss.|
|Emboss Red:||When set to a Green Check Mark, the Red Channel is included in the Emboss. When set to a Red X, the Red Channel is not included in the Emboss.|
|Emboss Green:||When set to a Green Check Mark, the Green Channel is included in the Emboss. When set to a Red X, the Green Channel is not included in the Emboss.|
|Emboss Blue:||When set to a Green Check Mark, the Blue Channel is included in the Emboss. When set to a Red X, the Blue Channel is not included in the Emboss.|
|Monochrome:||When set to a Green Check Mark, the output is monochrome (grey scale) rather than color. When set to a Red X, the channel colors themselves bleed into the Emboss. Larger Emboss Strength will produce, generally, more colorful results.|
|Fit To Brush:||If set to a Red X the Effect spans the screen such that as you paint you reveal the Effect. When set to a Green Check Mark the Effect is sized to the brush such that as you paint the entire Effect is within the brush itself.|
|Output Color 1:||By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.|
|Output Color 2:||By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.|
To show a use for the Drawing Emboss Effect we started by placing our orchid photo into the Drawing buffer. The photo looks like this:|
We then did a default Emboss with the Emboss Strength set to the default value of 1 and in Monochrome:
In the next image we set the Strength to 6 and turned Monochrome Off:
Because Monochrome was turned off the RGB Channel colors themselves were strengthened with the Emboss.
