IDrawable

An abstract image that determines itself how it is displayed. Essentially an abstraction from vector and raster graphics.

Public Types

---

Params

struct IDrawable::Params

Empty structure.

Public Methods

draw

---

virtual void IDrawable::draw(IRenderer& render, const IDrawable::Params& params)

Called when the image needs to be displayed. It is assumed that the renderer is already set to the desired state (coordinates, color, etc.)

getSizeHint

---

virtual glm::ivec2 IDrawable::getSizeHint()

Returns

Size of the stored image. Can be ignored by the renderer. If the size is unknown, it can be {0, 0}

isDpiDependent

---

virtual bool IDrawable::isDpiDependent()

Returns

true if the size hint of this drawable needs to be multiplied by the DPI ratio

rasterize

---

virtual AImage IDrawable::rasterize(glm::ivec2 imageSize)

Converts possibly vector drawable to a raster image.

Arguments

imageSize

image size

Returns

rasterized image

TODO Unimplemented for all drawables except raster image and svg
