Start with a complete electric wolf composition
Neon Line Drawer opens with the exact electric-wolf reference composition: the detailed wolf, planet, spiral galaxy, waveforms, geometric shapes, stars, and original synthwave grid are all present with their original proportions and colors. The reference sits on its own editable canvas layer, so Eraser can remove only the pixels you pass over and Undo can restore them. Clear removes the full sample and automatically opens a clean perspective grid for a completely new composition.
Pen follows the pointer directly for precise hand-drawn corners, Glow Brush paints a visibly wider luminous body with a much larger halo, and Spray Brush lays down a responsive field of glowing particles whose spread and density grow with Line Thickness. The spray renderer groups particles into lightweight color-and-glow batches, keeping longer gestures smooth without losing the misty neon finish. Lines opens a picker for Straight, Curved, Dashed, Dotted, and Dash-Dot strokes. Curved first creates a straight editable segment: hold and drag anywhere along it to add as many bend points as needed, reposition existing bends, and Undo or Redo each reshape. Selecting Shapes opens a picker containing circles, triangles, squares, diamonds, pentagons, hexagons, octagons, stars, hearts, arrows, lightning bolts, and crosses. Eraser removes only the portion touched by its continuous sweep instead of deleting the full path; while Eraser is selected, Line Thickness becomes Eraser Size and ranges from a small precise cut to a broad removal area. Symmetry mirrors the current stroke across the center, and Mirror Draw can apply that behavior to every drawing tool.
Control the light instead of accepting one fixed effect
Line Thickness changes the bright core of each new stroke. Glow Intensity controls both the colored bloom and the fine luminous center, while Blur changes the softness of the surrounding light. Smoothness steadies curved gestures and Opacity blends new marks into the composition. The color row uses the same saturated cyan, electric blue, violet, hot pink, orange, yellow, and acid-green family seen in the reference, plus a true multicolor gradient. The Background picker starts with the same near-black tone as the wolf artwork, or it can be changed to any custom color without altering the drawing. Trails now adds an unmistakably wider outer aura to user-drawn lines. Pulse Animation visibly breathes cyan and magenta light over the stage through a lightweight composited overlay instead of repeatedly repainting every path.
The wolf opens with its original perspective grid intact, while the separate drawing grid stays suppressed so the sample never receives doubled lines. Clear removes the sample and automatically reveals one clean editable-canvas grid; the Grid switch then controls that layer for new artwork.
Cyber Blue, Laser Pink, Electric Mix, Aurora, Rainbow Pulse, Neon Green, and Synthwave are distinct drawing presets rather than thumbnail-only themes. Selecting one changes the colors placed along each new path, so Electric Mix blends cyan through violet into pink and Rainbow Pulse uses the full spectrum. Selecting an individual color returns to a solid neon stroke. New lines receive a narrow pale core, saturated colored tube, controlled bloom, and optional outer trail so they can match the preloaded artwork without turning white or looking overexposed.
Save the frame or record the drawing process
Export PNG renders the current canvas at high resolution, including the loaded sample and every stroke added on top. Record captures only the artwork canvas and downloads the video when recording stops. Fullscreen expands the studio for large mouse, pen, or touch gestures. The top, left, right, bottom, and performance panels each have an arrow that hides the full panel and leaves only its arrow visible. Collapsing the preset rail also collapses the adjacent FPS, Active Paths, and GPU panel. On smaller screens, the performance panel is removed completely and the larger control panels begin collapsed so the drawing area remains usable.
The exact supplied electric-wolf scene loads as an erasable canvas layer, preserving its intricate facial detail, fine line weight, saturated colors, and restrained glow instead of replacing it with a rough approximation. Its perspective floor is separated into one switchable grid, so the control works without doubling the grid beneath the wolf. Eraser changes only the touched part of the sample, Undo restores it, and new marks remain editable strokes above it. Finished artwork is cached, only the active stroke is repainted while drawing, device resolution is bounded, and long gestures are simplified as they grow. The active preset is indicated by its border and underline only; no thumbnail receives an extra check mark.
