Detailed Description

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

Member Function Documentation

◆ indexToRect()

iaarect tt::pipeline_image::Image::indexToRect ( int const pageIndex ) 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.

◆ placeVertices()

void tt::pipeline_image::Image::placeVertices	(	vspan< vertex > &	vertices,
		matrix3	transform,
		aarect	clippingRectangle )

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

◆ extent

i32x4 tt::pipeline_image::Image::extent

The size of the image in pixels.

◆ pageExtent

i32x4 tt::pipeline_image::Image::pageExtent

This size of the image in pages.

This value is used to calculate how many quads need to be drawn.
