Detailed Description

Definition of a rounded rectangle shape.

When drawing a rounded rectangle it doesn't get blended on the surface but replaces the pixels instead. A blitting flag might be added later if needed.

Key Type Default Description
corner_radius f_unsigned0 The radius of the rectangle's corners.
border_thicknessunsigned 0 The thickness of the border; if the thickness is zero it's not drawn.
border_color color "" The color of the border; if empty it's not drawn.
fill_color color "" The color of the interior; if omitted it's not drawn.
debug string "" Debug message to show upon creation; this message is not stored.

wfl::map_formula_callable variables 
)
overridevirtual

Draws the canvas.

Parameters
canvasThe resulting image will be blitted upon this canvas.
rendererThe SDL_Renderer to use.
view_boundsPart of the shape to render - this is the location of canvas within the coordinates of the shape.
variablesThe canvas can have formulas in it's definition, this parameter contains the values for these formulas.
