Member Function Documentation

bitmap()

RefPtr< Bitmap > ultralight::BitmapSurface::bitmap

(

)

Get the underlying Bitmap.

height()

virtual uint32_t ultralight::BitmapSurface::height ( ) const

overridevirtual

Height (in pixels).

Implements ultralight::Surface.

LockPixels()

virtual void * ultralight::BitmapSurface::LockPixels ( )

overridevirtual

Lock the pixel buffer and get a pointer to the beginning of the data for reading/writing.

Native pixel format is premultiplied BGRA 32-bit (8 bits per channel).

Implements ultralight::Surface.

operator=()

void ultralight::BitmapSurface::operator= ( const BitmapSurface &  )

protecteddelete

Resize()

virtual void ultralight::BitmapSurface::Resize ( uint32_t  width, uint32_t  height  )

overridevirtual

Resize the pixel buffer to a certain width and height (both in pixels).

This should never be called while pixels are locked.

Implements ultralight::Surface.

row_bytes()

virtual uint32_t ultralight::BitmapSurface::row_bytes ( ) const

overridevirtual

Number of bytes between rows (usually width * 4)

Implements ultralight::Surface.

size()

virtual size_t ultralight::BitmapSurface::size ( ) const

overridevirtual

Size in bytes.

Implements ultralight::Surface.

UnlockPixels()

virtual void ultralight::BitmapSurface::UnlockPixels ( )

overridevirtual

Unlock the pixel buffer.

Implements ultralight::Surface.

width()

virtual uint32_t ultralight::BitmapSurface::width ( ) const

overridevirtual

Width (in pixels).

Implements ultralight::Surface.
