Pixmap::Sample

This method retrieves a pixel sample using bilinear filtering to smoothly interpolate between pixels. This can also be used to read color values from high-precision pixel formats.

Syntax

• Vec4 Sample(const float u, const float v)
• Vec4 Sample(const Vec2& coords)
• Vec4 Sample(const iVec2& coords)

Returns

Returns a bilinear filtered pixel sample at the specified coordinate.

If the pixmap uses a compressed format Vec4(0) will be returned.

Remarks

Float coordinates will be clamped to the range 0.0-1.0.

If coord is an iVec2 bilinear filtering will not be used.
