Name
mult_imagemult_imageMultImageMultImage — Multiply two images.
mult_imagemult_imageMultImageMultImageMultImage multiplies two images. The gray values
(g1,g2) of the input images (Image1Image1Image1Image1image1) are
transformed as follows:
g' := g1 * g2 * Mult + Add
If an overflow or an underflow occurs the values are clipped.
Note that this is not the case with cyclic and direction images.
Several images can be processed in one call. In this case
both input parameters contain the same number of images
which are then processed in pairs.
An output image is generated for every pair.
mult_imagemult_imageMultImageMultImageMultImage can be executed on an OpenCL device for byte, int1, int2,
uint2, int4, real, direction, cyclic, and complex images. However, since
for OpenCL 1.0 only single precision floating point is supported for all
devices, and not all rounding modes are supported, the OpenCL implementation
can produce slightly different results from the scalar implementation.
- Supports OpenCL compute devices.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
- Automatically parallelized on channel level.
- Automatically parallelized on domain level.

The operator mult_imagemult_imageMultImageMultImageMultImage returns the value 2 (H_MSG_TRUE) if the
parameters are correct. The behavior in case of empty input (no
input images available) is set via the operator
set_system(::'no_object_result',<Result>:)set_system("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)SetSystem("no_object_result",<Result>)
If necessary an exception is raised.
