MImage_setReal (C Function)

sets a single element of an MImage of MImage_Type_Real type.

Details

Used in C/C++ code in a library function called from the Wolfram Language.
Uses the same numbering scheme as the Wolfram Language parts, i.e. the first element is 1.
The array is assumed to have length at least equal to the rank of .
In 2D, the first two elements of are assumed to be {row,column}.
In 3D, the first three elements of are assumed to be {slice,row,column}.
A nonzero error code value will be returned if the element does not exist or if is not an MImage of MImage_Type_Real type.

This sets the pixel at position 2,3 and channel 1 to be 1.0:

MImage I0;
mint pos[2];
int err;
...
pos[0] = 2;
pos[1] = 3;
err = libData->MImage_setReal(I0, pos, 1, 1.0);
