Image Processing

These nodes edit, split, resize, or encode images. A socket is an input or output point on a node.

Annotation

Draw instructions or marks over an image.

Inputs: A connected image or an uploaded PNG, JPEG, or WebP file, up to 10 MB.

Outputs: The image with your annotations.

Setting	Effect
Editor tools	Select, rectangle, circle, arrow, freehand, and text.
Color and width	Eight colors and three stroke widths.

Split an image into cells and create a node set for each cell.

Inputs: One source image.

Outputs: Cell images supplied to the generated per-cell node sets.

Setting	Effect
Rows and columns	1–16 on each axis. The initial grid is 2 rows × 3 columns.
Slice lines	Drag boundaries to create unequal cells.
Open cell editor	Edit the reusable node template for each cell. The initial template contains Image Input.
Layout	Grid, vertical, or horizontal placement for the generated node sets.
Shared Router	Template terminal outputs can feed one shared downstream Router.
Split rows × columns now	Creates the cell groups and fills their base Image Input nodes.

Build a processing chain once in the cell editor, which supports every node type.
With unchanged dimensions and template, another split preserves cell edits. A changed layout or template can rebuild the node sets.

Remove an image background in the browser.

Inputs: One image.

Outputs: The image with its background removed.

Setting	Effect
Model	Fast, Balanced, or Quality. The default is Balanced.

Start with Balanced. Use Fast or Quality to change the speed and quality tradeoff.

Resize an image before another processing step.

Inputs: One image.

Outputs: One resized image.

Setting	Effect
Mode	Exact dimensions, Max edge, or Scale %.
Dimensions	Positive pixel dimensions. Scale accepts 1–400%.
Exact fit	Contain, Cover, or Stretch.
Format	Keep, PNG, JPEG, or WebP.
Quality	0.1–1 for JPEG and WebP. The default is 0.9.

Use Max edge to preserve proportions. The longest output edge cannot exceed 8192 pixels.
The initial settings are Exact, 128×128, Contain, and PNG.

Combine image frames into an animated GIF.

Inputs: At least two ordered image frames.

Outputs: An animated GIF through an image socket.

Setting	Effect
Frame order	Reorder the filmstrip before encoding.
FPS	Frames per second, from 1 to 30. The default is 8.
Colors	Palette size from 2 to 256. The default is 128.
Dithering	Adds a pattern to approximate missing colors. Initially disabled.
Target size	Optional size tuning. The default target is 128 KiB.

Resize frames consistently first. The encoder caps the longest edge at 1024 pixels.
Target-size tuning can reduce colors, dimensions, and frame count. It does not guarantee the target size.
