BaseTextGL (object)

バージョン 2.4.0 で追加.

BaseTextGL extends FreeTypeGL to draw 2D text and 2D primitives with FabricOGL. It’s in charge of generating and binding the OpenGL buffers. It also provides high level methods to push or insert text to draw.

参考

FreeTypeGL, Text.

Members

UInt32	indexSize	Size of the index.
UInt32	vertexSize	Size of the vertex.
UInt32	maxVerticesCount	Number max of vertices per element.
UInt32	elementCount	Number of element to draw.
UInt32	programId	Shader program id. Use to bind the buffers.
Ref<AtlasGL>	atlas	Reference to the atlas. Used to add text.
UInt32	attributesCount	Number of GLSL attributes.
