TouchDraw uses the standard iOS gestures to zoom a drawing. Refer to the following table to learn more about available zoom gestures:
|Zoom In||To zoom in on an area (make it larger), first make sure the Move, Zoom and Selection Tool is active. Place two fingers on the drawing canvas and slowly spread them apart. The drawing will zoom in on the area between the two fingers as they are spread.|
|Zoom Out||To zoom out of a drawing (make it smaller), place two fingers on the drawing canvas (as above); however, in this case the two fingers are pinched by slowly bringing them together. The drawing will zoom out based on how far the two fingers come together as the pinching action occurs.|
|Zoom To Fit||If the Move, Zoom and Selection Tool is active and a triple tap is performed anywhere in the drawing canvas, the drawing will be zoomed to fit into the drawing view.|
|Zoom To Origin||If the Move, Zoom and Selection Tool is active and a quadruple tap is performed anywhere in the drawing canvas, the zoom level will be reset to 100% and the origin of the drawing will be repositioned so that 0,0 is in the upper left hand corner.|
|Panning||If the Move, Zoom and Selection Tool is active, place two fingers on the drawing canvas and them drag them around to pan around a drawing.|
Note: The panning and zooming gestures can be combined into one fluid gesture to quickly zoom and move to the target portion of a drawing.
