Image Solid - Generate solid-color canvas

Node Purpose: Image Solid creates solid-color images with optional alpha scaling, inversion, and mask opacity. Supports preset sizes or custom width/height, optional divisibility constraints, and size inference from a reference image.

Inputs

Name	Port	Type	Default	Range	Description
get_image_size	optional	IMAGE	-	-	Reference image for size inference when generating per-frame canvases.
preset_size	-	COMBO	custom	presets	Target size preset; when not custom, overrides width/height.
width	-	INT	1024	1–8192	Target width when preset_size=custom.
height	-	INT	1024	1–8192	Target height when preset_size=custom.
color	-	STRING	1.0	Gray/HEX/RGB/name/single-letter	Base color; supports 0..1 gray, R,G,B, HEX, named colors, and single-letter color aliases.
alpha	-	FLOAT	1.0	0.0–1.0	Global alpha applied to color channels.
invert	-	BOOLEAN	False	-	Invert color channels before applying alpha.
mask_opacity	-	FLOAT	1.0	0.0–1.0	Mask intensity for output mask.
divisible_by	-	INT	8	1–1024	Enforce size to be multiples of this value.

Outputs

Name	Type	Description
image	IMAGE	Solid-color image batch.
mask	MASK	Corresponding mask batch at mask_opacity.

Features

• Flexible sizing: use preset_size or custom width/height; optionally infer size from get_image_size per frame.
• Preset addition: now includes a 256×256 square preset for quick thumbnails or small-canvas testing.
• Color parsing: supports gray (0..1), HEX (#RRGGBB), R,G,B, named colors, and single-letter aliases.
• Single-letter aliases include entries such as r/b/c/m/y/k/w; note that g maps to lime rather than green.
• Alpha/invert: applies alpha scaling; invert=True flips channels before alpha.
• Divisibility: rounds up dimensions to be divisible by divisible_by.

Typical Usage

• Create a background canvas with a specific color and mask intensity.
• Generate per-frame solid canvases matching a reference batch via get_image_size.
• Prepare model-sized inputs quickly using presets and divisible_by.

Notes & Tips

• Mask is full ones scaled by mask_opacity and matches the image size.
• Color values are applied in channels-last layout and clamped to [0,1].
