|

* @short_description: Functions that draw various primitive shapes and
|
||||
* allow for construction of more complex paths.
|
||||
*
|
||||
* There are three levels on which drawing with cogl can be used. The
|
||||
* highest level functions construct various simple primitive shapes
|
||||
* to be either filled or stroked. Using a lower-level set of functions
|
||||
* more complex and arbitrary paths can be constructed by concatenating
|
||||
* straight line, bezier curve and arc segments. Additionally there
|
||||
* are utility functions that draw the most common primitives - rectangles
|
||||
* and trapezoids - in a maximaly optimized fashion.
|
||||
*
|
||||
* When constructing arbitrary paths, the current pen location is
|
||||
* initialized using the move_to command. The subsequent path segments
|
||||
* implicitly use the last pen location as their first vertex and move
|
||||
* the pen location to the last vertex they produce at the end. Also
|
||||
* there are special versions of functions that allow specifying the
|
||||
* vertices of the path segments relative to the last pen location
|
||||
* rather then in the absolute coordinates.

* @short_description: Functions that draw various primitive shapes and
|
||||
* allow for construction of more complex paths.
|
||||
*
|
||||
* There are three levels on which drawing with cogl can be used. The
|
||||
* highest level functions construct various simple primitive shapes
|
||||
* to be either filled or stroked. Using a lower-level set of functions
|
||||
* more complex and arbitrary paths can be constructed by concatenating
|
||||
* straight line, bezier curve and arc segments. Additionally there
|
||||
* are utility functions that draw the most common primitives - rectangles
|
||||
* and trapezoids - in a maximaly optimized fashion.
|
||||
*
|
||||
* When constructing arbitrary paths, the current pen location is
|
||||
* initialized using the move_to command. The subsequent path segments
|
||||
* implicitly use the last pen location as their first vertex and move
|
||||
* the pen location to the last vertex they produce at the end. Also
|
||||
* there are special versions of functions that allow specifying the
|
||||
* vertices of the path segments relative to the last pen location
|
||||
* rather then in the absolute coordinates.

* allow for construction of more complex paths.
|
||||
*
|
||||
* There are three levels on which drawing with cogl can be used. The
|
||||
* highest level functions construct various simple primitive shapes
|
||||
* to be either filled or stroked. Using a lower-level set of functions
|
||||
* more complex and arbitrary paths can be constructed by concatenating
|
||||
* straight line, bezier curve and arc segments. Additionally there
|
||||
* are utility functions that draw the most common primitives - rectangles
|
||||
* and trapezoids - in a maximaly optimized fashion.
|
||||
*
|
||||
* When constructing arbitrary paths, the current pen location is
|
||||
* initialized using the move_to command. The subsequent path segments
|
||||
* implicitly use the last pen location as their first vertex and move
|
||||
* the pen location to the last vertex they produce at the end. Also
|
||||
* there are special versions of functions that allow specifying the
|
||||
* vertices of the path segments relative to the last pen location
|
||||
* rather then in the absolute coordinates.
