**-swizzle _rgbamask_**: When doing the ``merge`` command, by default it uses the Blue channel from the second image as the Alpha channel for the output; pulling Red, Green, and Blue from the original image which is same as the mask ``rgbB``. This option lets you provide alternative channel patterns using [HLSL-style](https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/dx9-graphics-reference-asm-ps-registers-modifiers-source-register-swizzling) swizzle masks. Lowercase letters indicate channels pulled from the first image (``rgbaxyzw``), and uppercase letters indicate the second image (``RGBAXYZW``). The mask is 1 to 4 characters in length.
