      Effect:Drawing Blur
      Category:Color Sources
      Speed:Fast

      Description: The Drawing Blur Effect lets you use your 'most recent' drawing as the color source with an added blur.

      The Drawing Blur Effect is identical to the Drawing Effect with the addition of a blur. This makes the Drawing have an out-of-focus look.

      If you enable the Fit To Brush Option you will paint with the Current Blurred Drawing sized to your brush.

      Reminder

      You 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.

       
      Options: The Drawing Blur Effect has the following Options Pane:

      X Blur Size:The Horizontal Blur Size. This can be a value from 1 to 100. This sets the blur filter size. The larger the number the more blur the object has. Very large numbers create a faceted blur.
      Y Blur Size:The Vertical Blur Size. This can be a value from 1 to 100. This sets the blur filter size. The larger the number the more blur the object has. Very large numbers create a faceted blur.
      Blur Red:If set to a Red X, the Red channel is not blurred. If set to a Green Check Mark the Red Channel is blurred.
      Blur Green:If set to a Red X, the Green channel is not blurred. If set to a Green Check Mark the Green Channel is blurred.
      Blur Blue:If set to a Red X, the Blue channel is not blurred. If set to a Green Check Mark the Blue Channel is blurred.
      Blur Alpha:If set to a Red X, the Alpha channel is not blurred. If set to a Green Check Mark the Alpha Channel is blurred.
      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.

      Example: To show a use for the Drawing Blur Effect we started by placing our orchid photo into the Drawing buffer. The photo looks like this:

      We then use Drawing Blur with a 3x3 filter (X and Y Blur Size both 3):

      Doing the same thing but using the highest setting of a 100x100 filter (X and Y Blur Size both 100), you can see how it begins to facet:
