offset()

int2 blender::draw::image_engine::TextureInfo::offset ( ) const

inline

return the offset of the texture with the area.

A texture covers only a part of the area. The offset if the offset in screen coordinates between the area and the part that the texture covers.

Member Data Documentation

batch

gpu::Batch* blender::draw::image_engine::TextureInfo::batch = nullptr

Batch to draw the associated text on the screen.

Contains a VBO with pos and uv. pos (2xI32) is relative to the origin of the space. uv (2xF32) reflect the uv bounds.

clipping_bounds

rcti blender::draw::image_engine::TextureInfo::clipping_bounds

area of the texture in screen space.

need_full_update

bool blender::draw::image_engine::TextureInfo::need_full_update

does this texture need a full update.

When set to false the texture can be updated using a partial update.
