Description

The operation increases the brightness of an image by multiplying each of its pixels by a fixed value.

\forall_{i,j} \text{\textbf{OutImage} }_{i,j} = \text{\textbf{InImage} }_{i,j} \cdot \text{\textbf{inValue} }

Whenever the resulting value exceeds the range of pixel values, it is clipped to the nearest proper value.

Examples

The MultiplyImage performed on the sample image with inValue = 2.0.

Hardware Acceleration

This operation is optimized for SSE2 technology for pixels of types: UINT8, SINT8, SINT16, REAL.

This operation supports automatic parallelization for multicore and multiprocessor systems.
