VipsImagecomplexform

Declaration [src]

int
vips_complexform (
  VipsImage* left,
  VipsImage* right,

)

Description [src]

Compose two real images to make a complex image. If either left or right are #VIPS_FORMAT_DOUBLE, out is #VIPS_FORMAT_DPCOMPLEX. Otherwise out is #VIPS_FORMAT_COMPLEX. left becomes the real component of out and right the imaginary.

If the number of bands differs, one of the images must have one band. In this case, an n-band image is formed from the one-band image by joining n copies of the one-band image together, and then the two n-band images are operated upon.
