Performance

TouchDraw supplies preference options for turning off certain features as images are rendered on the drawing canvas. These preferences are located in the Performance section of the Application Preferences popup window, as shown below.

Enabled preferences have a check mark in their associated box.

Preference Name Description
Fast Zoom The Fast Zoom preference hides text and additional items during zooming to increase rendering speed within the drawing editor. These items are not actually removed from the drawing.

Hide Handle Shadows The Hide Handle Shadows preference hides handle shadows while images are being rendered within the drawing editor. This does not mean that shadows have been removed from the drawing. Instead, shadows are not drawn in the editor to provide increased rendering speed.
