Multi Image Stitch - Directional Concatenation with Spacing

Node Purpose: Multi Image Stitch stitches multiple images in a chosen direction (top, bottom, left, right) with configurable spacing width and color. Supports match-by-resize or match-by-padding and handles batches safely.

Inputs

Name	Port	Type	Default	Range	Description
direction	-	COMBO	right	top / bottom / left / right	Stitch direction.
match_image_size	-	BOOLEAN	True	-	Match sizes by resizing when True; otherwise pad to unify.
spacing_width	-	INT	10	0–1000	Spacer thickness between images.
spacing_color	-	STRING	1.0	grayscale/HEX/RGB/name	Spacer color.
pad_color	-	STRING	1.0	color strategy for padding	Padding strategy or color.
image_1	-	IMAGE	-	-	First image.
image_2…image_N	optional	IMAGE	-	-	Additional images recognized by numeric suffix ordering.

Outputs

Name	Type	Description
image	IMAGE	Stitched image batch; clamped to [0,1] float.

Features

• Iterative stitching: stitches images pairwise in order image_1..N.
• Batch broadcasting: repeats smaller batches to match larger ones.
• Two matching modes:
• Resize keep ratio: when match_image_size=True.
• Pad to unify: when match_image_size=False with pad_color strategies.
• Spacers: vertical or horizontal strips with spacing_color; spacing_width=0 yields no gap.
• Advanced padding: extend, mirror, edge, average, or explicit colors.

Typical Usage

• Collage creation: concatenate images into banners or columns with controlled spacing.
• Consistent layouts: use resize matching to keep proportions; use padding to preserve entire content.
• Batch-safe stitching: combine batched images with automatic broadcasting.

Notes & Tips

• spacing_color supports grayscale floats, R,G,B in 0..1 or 0..255, #hex, and common names.
• For precise alignment in left/right, target heights are unified; for top/bottom, target widths are unified.
