Nodes

Image Batcher

Creates batches of images in connection order.

Inputs:

• image_1 to image_6: IMAGE (optional)
• count_1 to count_6: INT (frames to use from each input, 0 = all)
• none_value_1 to none_value_6: STRING (RGB color like "127,127,127")
• max_frames: INT (batch size limit, 0 = unlimited)

Outputs:

• images: IMAGE (batched images)

Mask Batcher

Creates batches of masks in connection order.

Inputs:

• mask_1 to mask_6: MASK (optional)
• count_1 to count_6: INT (frames to use from each input, 0 = all)
• none_value_1 to none_value_6: FLOAT (alpha value 0.0-1.0)
• max_frames: INT (batch size limit, 0 = unlimited)

Outputs:

• masks: MASK (batched masks)

Image Mask Batcher

Creates synchronized batches of images and masks.

Inputs:

• image_1 to image_6: IMAGE (optional)
• mask_1 to mask_6: MASK (optional)
• count_1 to count_6: INT (frames to use from each pair, 0 = all)
• image_none_value_1 to image_none_value_6: STRING (RGB color)
• mask_none_value_1 to mask_none_value_6: FLOAT (alpha value)
• max_frames: INT (batch size limit, 0 = unlimited)

Outputs:

• images: IMAGE (batched images)
• masks: MASK (batched masks)

Image Copy Paste

Copies source image onto destination with alignment options.

Inputs:

• source: IMAGE (image to copy)
• destination: IMAGE (background image)
• alignment: STRING (center, top, bottom, left, right)
• scale: FLOAT (scale factor, default 1.0)
• x_adjustment: INT (horizontal offset)
• y_adjustment: INT (vertical offset)
• mask: MASK (optional, modulates source area)

Outputs:

• image: IMAGE (combined result)
• mask: MASK (placement mask showing where source was copied)

Behavior: Source is resized to fit within destination, then positioned according to alignment. Scale is applied after fit-sizing.

Empty Image Batch / Empty Mask Batch

Generate empty batches for workflow initialization.

Inputs: None

Outputs:

• empty_batch: IMAGE or MASK (empty batch with shape (0,1,1,3) or (0,1,1))
