Align your grids

Step 1 has two parts: you choose your art, then line it up with the real surface here. You work on one grid at a time, and the grid you’re editing is the active grid.

Choosing the active grid

• Tap a numbered tile along the top.
• Or, with Auto Grid Select on, just touch the picture: the grid under your finger is selected (the top one, if grids overlap).
• To reach a grid that’s hidden behind others, turn Auto Grid Select off and use the numbered tiles.

The strip scrolls sideways if you have many grids. A press that turns into a scroll doesn’t select anything.

Add, remove, duplicate, change art

Control	What it does
+ GRID	Adds a new grid on top.
− GRID	Removes the active grid. You can’t remove the last one.
CHANGE ART	Opens the artwork picker for the active grid. Its alignment, masks and colors are kept.
Press and hold a numbered tile (about ⅔ of a second)	Duplicates that grid. The copy sits on top and keeps the media, corners, size and rotation, color, key, speed, sound and mask membership.

Moving the corners

Each grid has four corner pins. Drag a pin to the matching corner of your surface. The picture is warped to fit exactly between the four pins.

If a pin is hard to reach, or the grid is partly off-screen:

1. Choose a corner in the Corner Selection box on the left.
2. Tap the NUDGE arrows to move that corner. Hold an arrow to keep nudging.

Nudging has no limits, so a corner can move beyond the edge of the picture.

Moving, scaling and rotating the picture

• One finger (or the mouse): drag the grid to move it.
• Two fingers: pinch to scale and twist to rotate.
• No pinch available (Mac)? Switch on Scale Controls and/or Rotation Controls on the right. An on-screen overlay appears with a width slider, a height slider and a rotation dial, each with arrows for small steps. Hold a control for a moment and the surrounding panels and pins clear away so you can see what you’re doing.

The sliders cover a normal range, but the arrows and gestures can go past the ends.

Right-hand panel

Control	What it does
Display All Effects	Turns masks, warp paint, color and the rest on or off so you can see the raw art while aligning.
Display Grid Overlay	Draws a grid of lines over the picture so you can judge straightness.
Auto Grid Select	See above. Saved with the project.
Layer Order (up/down arrows)	Moves the active grid forward or backward in the stack.
Rotation Controls / Scale Controls	Show the transform overlay (above).

Left-hand panel

Control	What it does
FULL RESET	Puts the active grid’s corners, position, size and rotation back to the starting state. You can undo it.
Undo arrow	Undoes the last change you made in Step 1. One step only, and it greys out once used.
Corner Selection / NUDGE	See above.
BACK	Leaves Step 1. In a new project it returns to the Main menu. When you came from a saved project it returns to the last saved version.
SAVE + CONTINUE	Saves and moves on to Step 2.

Tip

Panels slide out of the way while you drag a pin or use a gesture, and return when you let go. The small chevrons at the edges collapse or expand each panel by hand.
