E2MAPPER is a PnP (Program and Preview) position calculator for the Barco E2 Event Master. Quickly calculate H Center, H Sym, V Center, V Sym and H Right values for any PnP configuration.

Left Edge: H Pos is measured from the left edge of the canvas to the left edge of the PnP. This is the E2 default.

Center Point: H Pos is measured from the left edge of the canvas to the center of the PnP.

· Tap any result card to copy the value to clipboard
· AR Lock keeps the aspect ratio when resizing
· Link Mode mirrors H Pos symmetrically across layers
· Drag layers in Preview to adjust position visually
· Layer images are rendered in Preview for real-world simulation

Set the canvas size using the preset chips (6720×1080, 3840×1080, etc.) or enter custom Width / Height values. Choose the coordinate basis — Left Edge is the E2 default.

Enter PnP Width, Height, H Pos and V Pos. Results update in real time. Tap any result card to copy. Switch to Formula view to see the calculation logic. Save configurations as presets for quick recall.

Add multiple PnP layers for complex configurations. Each layer has independent size, position, aspect ratio lock, and an optional image for preview simulation. Tap ✕ Remove to delete a layer. Use the Sync buttons to copy calculated positions from one layer to another.

Distribute Even — spreads all layers with equal margins across the canvas width.
By Gap — places layers left-to-right with a fixed gap between each.
Group Move — shifts all layers by a Δ offset.
Layout Templates — built-in presets (2× Sym, 4× Even, L/R, All Center). Save and load your own templates.

Visual canvas showing all layers in real time. Drag layers to adjust position. Toggle Grid and Labels. Upload a background image to simulate the final output. On iPhone, a mini preview is always visible in the Settings tab; tap Open Full for a full-screen popout window.
