Artstr Studio — TODO

Running list of deferred work. Detailed specs for the larger items live in docs/. Each entry notes scope and where the spec is (if any).

Adam's working list

• Click-canvas-background-to-deselect. In the vector canvas editor, clicking on empty canvas (outside any layer) should clear the layer selection. Today the selection persists, which makes it hard to "exit" a selected layer without picking another one.
• Toggle crop marks for export previews. A new toggle in the vector designer to hide crop marks from the PDF Print/Save and JPEG Export flows. Today crop marks bleed into clean exports.
• Custom-art canvas size from imported background URL. When a user pastes a background image URL on a Custom Art canvas, offer a one-click "Match canvas to image size" button (or apply automatically on first import) so the canvas dims = image dims. Edge cases: huge images (clamp to CUSTOM_ART_MAX), aspect-locked layouts (Slide is locked 16:9 — should be skipped or warn).
• JPEG export: hide layer-selection outlines. The Save-as-JPEG flow currently renders the selected-layer dashed outline in the output. Add body.exporting (or similar) state that strips selection chrome before the raster snapshot.
• One-click JPEG export (skip the PDF round-trip). Today the flow is: print → user saves PDF → user re-picks PDF → PDF.js converts to JPEG. We can't cache the PDF in between — window .print() doesn't expose the generated bytes to JS. Instead, write a direct canvas rasterizer that walks the layer model (image / text / shape / color / qr / pixelart) and draws each layer onto an off-screen canvas at the artboard's design dims, then toBlob('image/jpeg'). Same approach the pixel-art PNG export already uses, generalised. CORS-tainted remote images (cross-origin host without Access-Control-Allow-Origin) would break the direct path — fall back to the existing PDF round-trip for those with a one-line "this image needs the PDF route" toast. Most modern image hosts (CDNs, Blossom blobs) send CORS so the fallback should be rare. ~300–500 LoC of layer-by-layer drawing code; reuses renderShapeIntoElement etc. as references for geometry but writes to canvas instead of DOM.
• Independent-axis corner-node resize. Corner resize handles currently lock the aspect ratio (or scale both axes together). Behaviour should follow the actual drag vector: dragging mostly horizontally with a small vertical move resizes width a lot, height a little — both axes scale proportional to their own movement, not to each other. Applies to every layer type's resize handles, not just text.

CORS for remote-image raster export

Quick reply, no action yet:

• The PDF Print/Save path renders via window.print() → the browser's native print/PDF engine, which handles cross-origin images fine. No CORS issue there.
• The JPEG export path already round-trips through PDF.js (PDF → JPEG), so it inherits the PDF path's CORS tolerance. If it's failing for some images, the root cause is likely the print path itself, not a canvas taint.
• The canvas-tainted situation only bites if we ever do a direct <canvas>.toBlob('image/jpeg') against a layout that contains a cross-origin remote <img> without CORS headers. Options if it becomes a real problem: (a) keep using the PDF.js round-trip; (b) recommend CORS-friendly hosts (Blossom blobs, ImgBB, most CDNs send Access-Control-Allow-Origin: *); (c) add an optional same-origin proxy endpoint — needs a server, which the app currently doesn't have.

QR code layer — remaining phases

Phases A and B shipped (the qr layer type: data, error-correction level, quiet zone, module / background colors, transparent background, renders on every surface + canvas export, JSON round-trip; plus "Insert npub" and "Insert share link" buttons under the QR data field).

• Phase C — visual polish. Optional center logo overlay and rounded modules. Riskier: a logo eats into the error-correction budget, so it should nudge the ECC level up. Skippable.

Editor / tool UX

Small editor-usability improvements — no spec doc; scoped here.

Shipped: on-canvas drag-resize handles for every layer type, text-box resize that never rescales the point size, the expanded Text tool panel (font / size / color / alignment / bold / italic), a collapsible sidebar toggle that fits the early-web aesthetic. Add new editor-UX items below.

Profile pages — deferred polish

(Core profile pages at /u/<npub> already shipped.)

• Make author chips clickable in the community thread view (comments and reposts) — currently only feed-card and preview-meta author chips route to openProfilePage.
• About-text clamp — long bios overflow the profile header; clamp to ~4 lines with a "Show more" toggle.
• Profile-grid pagination — an author with 100+ designs renders them all at once; cap the initial render and add a "Show more" pager.

Edit-published-designs — deferred polish

(Core edit-in-place via NIP-33 replaceable semantics already shipped.)

• Replace the remaining confirm() calls in the edit / publish flow with the styled in-app modal pattern, for consistency with the close-project and publish-confirm modals.
• "Editing a previously-deleted design" warning — if the user opens Edit on a design they had tombstoned with a kind-5, warn that publishing will republish it.

Pixel art — future polish

• pixelsB64 size-fallback encoder. The spec calls for each frame to store whichever is smaller: pixels (RLE pairs) or pixelsB64 (base64 of the raw Uint8Array of indices). Only RLE is implemented today. For noisy / photo-pixelized content with many palette colours, base64 is ~5× smaller — a 24-frame 64×64 sprite tested at 785 KB RLE would drop to ~150 KB. Worth shipping alongside a live event-size readout in the editor (soft warn at 50% of relay budget, hard block at 90%) so users see the budget before publish.

Drafted-but-unbuilt features

Each has a full spec in docs/.

• Private (encrypted) publishing — docs/PRIVATE_PUBLISHING_FEATURE.md. Publish any design encrypted, readable only by the author (Phase 1 "private to me"). The agreed next build; Phase 0 is a validation spike.
• Artstr Stacks — docs/STACKS_FEATURE.md. Interactive fullscreen page/card stacks (HyperCard for Nostr) — the Slide Deck extended with layer actions and an interactive viewer. Queued after private publishing.
• Badges (NIP-58) — docs/BADGES_FEATURE.md. Award / display Nostr badges on profile pages.
• Collections (NIP-51 sets) — docs/COLLECTIONS_FEATURE.md. Let users organize favorite community templates into named sets.
• Zap-gated premium templates — docs/ZAP_GATED_TEMPLATES_FEATURE.md. Creators mark a template premium with a minimum-zap threshold.
• Zaps via Nostr Wallet Connect — docs/ZAPS_NWC_FEATURE.md. In-app zapping without the wallet handoff. (Tracked LNURL-pay tips already ship; this would be the NWC path.)

Shipped (recent)

• Slide deck PDF export — multi-page PDF, one page per slide. The existing Print / Save PDF button is context-aware: in the Deck Builder it builds a hidden print-only container with one page per slide (themed via composeSlideForDeck, each page sized to the preview's native dimensions so the slide fills the page exactly) and emits one PDF via window.print(). Inside a single-slide editor, the button still prints just that slide.

• Copy / paste transform consistency — paste now computes a single group bounding box across all clipboard items, applies one shared scale (only shrinks, never enlarges) and one shared translation, so cross- target paste keeps every layer's relative position and size to the others intact.

• Pixel-editor colour picker — ported the OS native <input type="color"> over from the vector tools (same swatch styling; opens the OS picker with its built-in eyedropper on click). Removed the Screen-Capture-API screen- eyedropper workaround (~170 lines of dead code). Palette swatches and the in-canvas eyedropper tool now sync the picker too, so grabbing a palette colour as the starting point for a tweaked variant just works.

• Pixel Art — docs/PIXEL_ART_FEATURE.md. Phases A–D all shipped: embedded pixelart layer + standalone casewrap-pixelart design, PNG / sprite-sheet / GIF export, drawing tools (line / rect / ellipse, flip / rotate, grid resize), animation (multi-frame timeline, playback, onion-skin), image → pixelize, and animated previews in every preview surface. Undo / redo integrated with the top-level toolbar.

• Pixel editor layout expansion — addressed by the collapsible sidebar (gives both the pixel and vector editors a lot more breathing room when needed).

• Print / Save event ID wrapping — the event-id <dd> already uses overflow-wrap: anywhere; word-break: break-word, so no horizontal scroll.

• TMDB auto-fill cleanup — docs/TMDB_AUTOFILL_FEATURE.md removed.
