Member Function Documentation

◆ createStream() [1/2]

std::unique_ptr< PixelStream > roo_display::FilledRect::createStream ( ) const

overridevirtual

Create a stream covering the full extents().

Implements roo_display::Streamable.

Definition at line 180 of file basic.cpp.

References color.

◆ createStream() [2/2]

std::unique_ptr< PixelStream > roo_display::FilledRect::createStream ( const Box & clip_box ) const

overridevirtual

Create a stream for the given clipped bounds.

Implements roo_display::Streamable.

Definition at line 184 of file basic.cpp.

References color.

◆ extents()

Box roo_display::FilledRect::extents ( ) const

inlineoverridevirtual

Return the bounding box encompassing all pixels that need to be drawn.

This method is called during a transaction and must not block or perform I/O.

Implements roo_display::Drawable.

Definition at line 139 of file basic.h.

References roo_display::RectBase::extents().

◆ getTransparencyMode()

TransparencyMode roo_display::FilledRect::getTransparencyMode ( ) const

inlineoverridevirtual

Return the transparency mode for pixels in this stream.

This is an optimization hint. The default is TransparencyMode::kFull, which is always safe. If pixels are guaranteed fully opaque or 1-bit alpha, return TransparencyMode::kNone or TransparencyMode::kCrude to enable faster blending paths.

Reimplemented from roo_display::Streamable.
