AD Poster Maker

Turns a bare image into a framed, poster-style layout: it scales the image down, wraps it in a border, sets it on a background canvas, and shifts it to one side so there's clean space left over - the kind of layout you'd drop a title or caption into. Handy for social posts, thumbnails, and anything where the raw generation needs a bit of presentation around it.

Where it fits

A finished image and a shareable image aren't the same thing. Posters, cover images, and social cards usually want margins, a frame, and negative space for text - not a full-bleed picture. Poster Maker builds that framing in one node so you don't have to composite a border and background by hand every time. It's the presentation-layer sibling of the pack's Mockup Maker: where Mockup Maker places your image into a scene, Poster Maker frames it on a clean canvas.

How it works

It scales the input image down by scale (so it doesn't fill the whole canvas), draws a border of border_size in border_color, and places the framed image onto a background of background_color, offset to the side named by position. Both the border and background colors offer a custom option that reads from their matching hex field. method is the resampling filter for the scaling. Optional watermark and original_image inputs let you brand the poster or bring in a second image for the layout.

The inputs that matter

• image - the picture to frame.
• scale - how big the image is within the canvas (0.1–1). Lower leaves more surrounding space.
• border_size / border_color - the frame thickness and color. Set border_color to custom to use border_hex.
• background_color - the canvas color. custom uses background_hex.
• position - which side the framed image sits on: left, right, top, or bottom. The opposite side is your open space for text.

The output is a single image - the composed poster.

Common issues

The custom-color gotcha applies twice here: border_hex and background_hex only take effect when the matching dropdown is set to custom. Type a hex while the dropdown still says white and you'll get white. The other thing to internalize is that position and scale work together to create your text space - a smaller scale plus a position of, say, right leaves a big empty band on the left for a title. If your poster feels cramped, drop the scale. And since this node only lays out the frame, the actual title text is on you - add it in your image editor or a text-drawing node afterward.
