Function Documentation

PresentedFramebufferFromDocumentTransform()

Transform2d donner::editor::PresentedFramebufferFromDocumentTransform	(	const ViewportState &	viewport,
		const Vector2d &	framebufferFromLogicalScale )

Resolve one camera mapping shared by pixel and chrome placement.

Parameters

viewport	Camera and logical pane geometry.
framebufferFromLogicalScale	Physical pixels per logical pixel, independently per axis.

PresentedImageClipRect()

std::optional< Box2d > donner::editor::PresentedImageClipRect ( const Box2d & paneRect, const Box2d & imageRect )

nodiscard

Intersect the artboard with the pane, refusing invalid or empty rectangles.

Parameters

paneRect	Logical pane clip.
imageRect	Artboard extent in the same coordinate space.

Returns

Clip rectangle for presented document pixels, or empty when a corner is not finite or the rectangles do not overlap.
