Methods¶
Methods in detail¶
FreeTypeGL ( in FreeTypeGL other )
copy constructor
FreeTypeGL ()
default constructor
FreeTypeGL.allocAndSetVerticesSize! ( in UInt32 elementCount, in UInt32 maxVerticesCount )
Allocation of the vertices and indices buffers for parallel insertion, and sets the size if the element to draw Buffers we be re-allocated if either “elementCount” or “maxVerticesCount” change. Must be called before inserting new vertices.
| elementCount | Number of string to draw. |
| maxVerticesCount | Maximin number of character per string. |
FreeTypeGL.allocVertices! ( in UInt32 elementCount, in UInt32 maxVerticesCount )
Allocation of the vertices and indices buffers for sequential insertion. Buffers we be re-allocated if either “elementCount” or “maxVerticesCount” change. Should be called before pushing vertices to avoid on the fly memory allocation that slows down the rendering.
| elementCount | Number of string to draw. |
| maxVerticesCount | Maximin number of character per string. |
FreeTypeGL.clearVertices! ()
Clears (but not delete memory) the vertices and indices buffers content. Need to be call before pushing a new set of vertices.
