Bit Depth Convert

Changes the bit depth metadata of an image.

Details

The internal float [0,1] data is unchanged. This node only updates the bit_depth tag so that saving and display use the target range.

Options:

• target_depth — output bit depth (8, 12, 14, 16)

Properties: Target Bit Depth

Zoom

Resizes an image by a zoom factor using high-quality Lanczos resampling.

Details

A factor of 2.0 doubles the size; 0.5 halves it. The preview overlay shows the actual output dimensions. Works with both ImageData and MaskData inputs.

• zoom — scale factor (default: 1.0).

Resize

Resizes an image or mask to an exact pixel size (width x height).

Details

• resize_width — target width in pixels (default: 300).

• resize_height — target height in pixels (default: 300).

• resample — resampling method: lanczos, bilinear, nearest, or bicubic.

Rotate

Rotates an image counter-clockwise by a given angle in degrees.

Details

The canvas is expanded to fit the full rotated image; surrounding areas are filled with black. Works with both ImageData and MaskData inputs.

• angle — rotation angle in degrees (default: 0.0).

Mirror / Flip

Flips or mirrors an image or mask along one or both axes.

Details

Axis options:

• horizontal — flip left-right (mirror across the vertical centre line)
• vertical — flip top-bottom (mirror across the horizontal centre line)
• both — flip both axes (equivalent to 180-degree rotation)

Works with both ImageData and MaskData inputs.
