Add images

Applies weights to two images, adds the weighted images together and outputs the result.

Inputs

• image1: Input image 1

• image2: Input image 2

• weight1: Weight of input 1

• weight2: Weight of input 2

• outputType: The type of the output image.

Outputs

• image: weight1 * image1 + weight2 * image2. In Automatic mode, the type of the output image depends on the type of the inputs as shown in the table below.

Type of output tabulated against type of image1 (columns) and image2 (rows) in Automatic output type mode.

	u8	s16	s32	rgb
u8	s16	s16	s32	rgb
s16	s16	s16	s32	rgb
s32	s32	s32	s32	rgb
rgb	rgb	rgb	rgb	rgb

• u8 = 8-bit unsigned gray

• s16 = 16-bit signed gray

• s32 = 32-bit signed gray

• rgb = 32-bit RGB with 8-bit unsigned channels

If the output type is u8 or rgb, overflows and underflows are handled by truncation. If the output type is s16 or s32, the tool takes no measures against such errors.
