Pixelblaze LED Mapper
Create 2D LED maps for Pixelblaze. If you are new to mapping, start with the Pixelblaze mapping guide.
Quick start
Set Grid X and Grid Y, then draw on the canvas. Use Load Background Image to trace a photo or layout if needed. Use Reset Background Image to remove the image without changing your map.
Drawing
Drag to draw a strip. Enable Point-to-Point to build connected point-to-point shapes. In Point-to-Point, the first point starts a shape and later points can continue it. Right-click finishes the current Point-to-Point shape.
Editing
Click a shape to select and edit it. Change LED count and start index in the popup. Use rotate, scale, flip, clone, and delete as needed. Drag points or whole shapes to reposition them. Click empty space or press Esc to clear the selection.
While a shape is selected, right-click a point to remove it, or right-click a segment to insert a new point.
LED settings
# of LEDs is how many LEDs are placed along the selected shape. Start Index is the first Pixelblaze LED number for that shape. Auto Index automatically advances the next shape so indices continue after the previous one.
Grid and output options
Scale existing shapes rescales your existing shapes when you change Grid X or Grid Y. If it is off, the grid changes but existing shapes keep their current size and position as much as possible. Coarse grid with snapping lets you add single LEDs snapped to the coarse grid. Precise outputs decimal coordinates instead of rounded integers.
Export and import
The Pixelblaze map is generated automatically in the read-only text box below the canvas. Use Copy Map to Clipboard to paste it into Pixelblaze. Use Export to save your work and Import to load it again.
Shortcuts
Arrow keys move the selected shape by 1 pixel. Hold C to show horizontal, vertical, and 45 degree guides. Del removes the selected shape. Esc clears the selection. Ctrl/Cmd+Z undoes and Ctrl/Cmd+Shift+Z or Ctrl/Cmd+Y redoes.
Note
Touch support is experimental. Desktop browser use is recommended.
