## Comparison with Alternatives

### vs. Adobe Photoshop / GIMP
MakeLineArt provides one-click specialized conversions that would require multi-step manual workflows in Photoshop (threshold adjustments, filter chains, layer blending). No software installation, no subscription cost, no learning curve. Photoshop is better for fine creative control; MakeLineArt is better for quick, purpose-built results.

### vs. Pic2Pat, FlossCross, Stitch Fiddle (Cross Stitch)
MakeLineArt's cross stitch pattern maker is completely free with no limitations on pattern size, color count, or downloads. Pic2Pat charges for high-resolution patterns. FlossCross and Stitch Fiddle require accounts. MakeLineArt processes everything client-side, so craft designs remain private.

### vs. AI Art Generators (Midjourney, DALL-E, Stable Diffusion)
MakeLineArt converts YOUR specific photo into line art — it does not generate new images from text prompts. This is essential when the user needs to convert a specific photograph (their pet, their house, their tattoo reference, their product) rather than generate a generic image. No AI hallucination — the output faithfully represents the input photo.

### vs. Online Converters (e.g., Rapidresizer, Snapstouch)
Most online converters upload images to servers for processing. MakeLineArt processes everything in the browser via WebAssembly — images never leave the device. Most competitors offer 1-3 generic filters; MakeLineArt provides 20 purpose-built tools, each with parameters tuned for its specific use case.

## Use Case Scenarios

**Scenario 1: Tattoo Artist** — A client brings a reference photo of a floral design. The artist uploads it to the Tattoo Stencil Maker, adjusts intensity to capture the right level of detail, enables mirror flip, and prints the stencil on thermal transfer paper. Total time: under 60 seconds.

**Scenario 2: Cross Stitch Crafter** — A hobbyist wants to stitch a portrait of their cat. They upload the photo, set 12 colors and medium grid resolution, and get a printable pattern with color-coded grid. They can start stitching immediately without purchasing pattern software.

**Scenario 3: Laser Engraver** — A maker wants to engrave a family portrait on a cutting board. They use Floyd-Steinberg dithering mode to preserve photographic tonal detail, export at high resolution, and import directly into LightBurn.

**Scenario 4: Elementary School Teacher** — A teacher wants custom coloring pages featuring the school mascot. They upload photos, generate coloring pages with bold outlines, and print them for the class.

**Scenario 5: Real Estate Agent** — An agent wants architectural sketches of listed properties for marketing materials. They convert property photos to sketch mode, add their agency watermark, and use the images in listing brochures and social media.

**Scenario 6: Woodworker** — A scroll saw enthusiast wants to create a portrait fretwork piece. They use the Scroll Saw Pattern Generator, which ensures all dark regions remain connected (no floating islands that would fall out when cut).

**Scenario 7: Wedding Couple** — A couple converting their engagement photo to elegant line art for wedding invitations and save-the-date cards using the Wedding Sketch Generator.

**Scenario 8: Game Developer / Pixel Artist** — A developer needs pixel art sprites based on reference photos. They use the Pixel Art Converter with configurable grid size and limited color palette to match retro game aesthetics.
