Detailed Description

This is a image that is uploaded into the texture atlas.

Member Function Documentation

◆ index_to_rect()

aarectangle tt::pipeline_image::image::index_to_rect ( size_t page_index ) const

noexcept

Find the image coordinates of a page in the image.

Parameters

pageIndex Index in the pages-vector.

Returns: The rectangle within the image representing a quad to be drawn. This rectangle is already size-adjusted for the quads on the edge.

◆ place_vertices()

void tt::pipeline_image::image::place_vertices	(	vspan< vertex > &	vertices,
		aarectangle	clipping_rectangle,
		matrix3	transform )

Place vertices for this image. An image is build out of atlas pages, that need to be individual rendered. A page with the value std::numeric_limits<uint16_t>::max() is not rendered.

◆ upload()

void tt::pipeline_image::image::upload ( pixel_map< sfloat_rgba16 > const & image )

noexcept

Upload image to atlas.

Field Documentation

◆ height_in_pages

size_t tt::pipeline_image::image::height_in_pages

The height of the image in pages.

◆ height_in_px

size_t tt::pipeline_image::image::height_in_px

The height of the image in pixels.

◆ width_in_pages

size_t tt::pipeline_image::image::width_in_pages

The width of the image in pages.

◆ width_in_px

size_t tt::pipeline_image::image::width_in_px

The width of the image in pixels.
