FloatRect pp::FloatRect::AdjustToFit ( const FloatRect & rect ) const

AdjustToFit() fits as much of the receiving rectangle within the supplied rectangle as possible, returning the result. For example, if the receiver had a x-location of 2 and a width of 4, and the supplied rectangle had an x-location of 0 with a width of 5, the returned rectangle would have an x-location of 1 with a width of 4.

Parameters

[in] rect A pointer to a FloatRect.

Returns: A FloatRect representing the difference between this rectangle and the receiving rectangle.

Definition at line 214 of file rect.cc.

References FloatRect(), height(), width(), x(), and y().

float pp::FloatRect::bottom ( ) const

This loop will access all the pixels in a horizontal line in the rectangle: for (float y = rect.y(); y < rect.bottom(); ++y) {}

Returns: The value of y + height for this point.
