Difference between revisions of "Dev:Types"

Each {{l|ValueNode}} (and hence each {{l|Parameter}}) in Synfig has one of 13(4) types:

* Bool -- a boolean value; true or false.  Represented in Studio as a checkbox

* Integer -- an integer value; a whole number.  -3 or 0 or 2 are examples.

* Real -- a [http://en.wikipedia.org/wiki/Real_number real number}}. -3.0, 0.0, 2.0 and 3.1415 are examples.

* Angle -- a real number that is interpreted as an angle

* Time -- a time, displayed in days, hours, minutes, seconds and frames

* Vector -- a 2d vector.  usually represented as two Reals representing X and Y values

* Color -- a color.  Usually represented as Red/Green/Blue/Alpha values

* Segment -- a single bezier curve segment.  Defined by 4 Vectors, representing 2 Vertices and 2 Tangents

* BLinePoint -- a point in a BLine.  Defined by 6 parameters (a Vector defining its location, a Real defining its width, another Real defining its origin, a Bool defining whether its tangents are split or not, and two Vectors defining the direction of its tangents (only the first of which is used if the tangents aren't split)

* List -- A list.  For example, an outline's Vertices parameter is simply a list of BLinePoint valuenodes.

* Canvas -- A collection of layers.  When you encapsulate layers, you're creating a new {{l|Paste Canvas}} layer called, by default "Inline Canvas".  The encapsulation layer has a parameter called 'Canvas' with type 'Canvas' and its value is the group of layers you've encapsulated.

* String -- a string of characters, for example "Hello Mum!"

* Gradient -- a range of colors (a mapping from a real parameter to a color).  Can be defined in many ways, but is usually editing using the gradient editor.
