Sketch-to-Image, Copy Design, Vectorize & Enhance

How to turn sketches into finished images, copy a design onto another image, trace line art into editable vectors, and refine or reverse-engineer prompts in Framo.

Sketch to Image (Realistic variant)

Turns a hand-drawn sketch on the canvas into a realistic image, with no style reference.

To use it:

1. Select the sketch image on the canvas.
2. Open the AI Tools menu (the wand button on the node toolbar) → Sketch Tools → Sketch to Image ("Turn a sketch into a realistic image").
3. In the dialog, type a few words for what the sketch shows (e.g. "sports car, front view") to keep the render on subject.
4. Optionally tick Clean up the sketch first (default off; adds credits) — recommended only for rough linework, skip it if your lines are already clean.
5. Click Generate.

The result lands as a new image on the canvas (the dialog closes immediately and progress is shown on a pending tile). In the Pixi edit canvas it lands as a layer instead.

Sketch to Image with Reference (Reference variant)

Same as above, but renders the sketch in the visual style of another image you pick.

To use it:

1. Select the sketch on the canvas, open AI Tools → Sketch Tools → Sketch to Image with Reference ("Render a sketch in a style you pick").
2. An eyedropper arms — click any image on the canvas to use it as the style reference (Esc cancels).
3. The same dialog opens (titled Sketch to Image · Reference): enter the subject, optionally tick Clean up the sketch first, click Generate.

The picked reference contributes style only; the sketch defines the composition. This variant is hidden inside the Pixi edit canvas (the on-canvas style pick can't run mid-edit).

Clean Sketch

Tidies a rough sketch's linework into a clean, shaded line drawing — no realistic render. The output is often useful on its own.

To use it: select the sketch, open AI Tools → Sketch Tools → Clean Sketch ("Tidies the linework — no render"). Enter a few words for the subject and click Generate. One render charge.

This is the same clean pass that the two Sketch-to-Image variants run when you tick "Clean up the sketch first" — exposed here as a standalone tool.

Copy Design

Transfers the design/styling of one image onto another (e.g. swap one car's body design onto your subject).

To use it:

1. Select the target image on the canvas.
2. Open AI Tools → Copy Design (eyedropper icon).
3. Pick an intensity from the submenu:
   • Subtle — light design hint
   • Balanced — clear design swap
   • Bold — reference dominates
4. An eyedropper arms — click the design-reference image on the canvas (Esc cancels).

The result generates onto the canvas. Higher intensity lets the reference dominate more. (This tool is hidden inside the Pixi edit canvas.)

Vectorize Sketch

Traces a raster layer's line work into smooth, editable Bézier paths (a native path layer you can keep editing with the pen tool). This runs on a layer inside the Pixi 2D editor.

To use it:

1. In the edit canvas, select a raster layer and trigger Vectorize from the layers panel.
2. In the Vectorize Sketch dialog, pick a trace mode:
   • Centerline — one stroked path per clean sketch line
   • Ridge — centerlines from shaded / tonal / faint art
   • Outline — closed loops around the ink boundary
3. Tune with the toggle and sliders, watching the live blue-path preview over the dimmed source:
   • Clean up lines (on by default) — merges tiny segments into long, smooth character lines; shows a Connect gaps slider for bridging fragmented strokes.
   • Ink threshold / Ridge strength — how much ink is captured (label depends on mode).
   • Line scale (σ) — ridge mode only.
   • Simplify (ε) — fewer, simpler anchors.
   • Smoothing — curve smoothness.
4. Click Create Path Layer. The trace lands exactly over the source layer; the footer shows path/anchor counts.

Prompt Enhance (inline panel)

Rewrites the prompt in your prompt field using AI. Available wherever the prompt enhancer panel appears in the prompt input.

• With text already in the prompt, four style buttons appear: Polish (sharpen and improve), Distill (strip to the essence), Enrich (add technical depth), Reimagine (transform and elevate). Click one to rewrite the whole prompt in that style.
• The chat box below is always available: type an instruction (e.g. "make it nighttime") to modify the prompt, or — when the prompt is empty — type an idea and the AI writes a full prompt. The mic button dictates by voice.
• If you highlight a fragment of the prompt first, the chat box scopes its edit to only that fragment.

Each enhance/chat action costs 1 prompt-enhancement credit.

Prompt Enhance (chat refinement)

A multi-turn chat for iterating on a generation prompt with the AI, opened from the chat bar. This is a Pro plan feature.

To use it:

1. In the chat bar's top row, click the wand button ("Refine prompt with AI"). (Free users get an upgrade dialog instead.)
2. Whatever you'd typed in the chat bar seeds the first message. Send follow-up instructions, or click a preset chip — Polish / Distill / Enrich / Reimagine — to refine. Each reply is a complete proposed prompt you can keep iterating on.
3. If you have reference images selected on the canvas, they show in the editable strip below the chat. Clicking a tile inserts an @image1, @image2, … mention at the cursor; typing @image2 (or "image 2") in your instruction points the AI at that numbered reference.
4. Click Use this prompt on any reply to accept it and return to the chat bar. Closing with the X discards the chat.

A word meter (top-right ring) tracks the free per-conversation allowance; closing resets it. See also the chat bar's Enhance pill, which is a separate one-shot toggle that auto-analyzes the input image and reconciles the prompt at generation time. See Chat bar: generating images.

Reverse Prompt (Default)

Generates a detailed, natural-language prompt that could recreate a selected image — useful for understanding or reusing an image's look.

To use it: select one image on the canvas, open AI Tools → Reverse Prompt → Default (1 credit). It analyzes the image and produces a single flowing prompt covering subject, composition, camera/lens, lighting, color, environment, style, and quality. In the result dialog you can Use Prompt (loads it into the prompt field), Regenerate, or Clear. There's also a Reverse Prompt popover (image icon) that does the same and lets you edit the text before using it.

Reverse Prompt (Structured)

Like Default, but returns a structured breakdown of the image (objects, lighting, aesthetics, photographic characteristics) instead of one paragraph.

To use it: select an image, open AI Tools → Reverse Prompt → Structured (2 credits). The result is shown as a structured analysis; Use Short Description loads its short description into the prompt field. Also available from the Reverse Prompt popover via the Structured toggle.

Reverse Prompt for HDRI (panorama)

Inside the HDRI generator, this analyzes a chosen image into a short, simple scene description tuned for 360° panorama generation (one sentence, location + key elements + lighting; no camera terms).

To use it: in the HDRI generator dialog, choose to create from an image, select your source image, and let it analyze. The resulting one-line description fills the Describe Scene step, where you can edit it before generating the panorama.
