Examples with Shape com.codename1.ui.geom.Shape used on opensource projects

Example 1 with Shape

use of com.codename1.ui.geom.Shape in project CodenameOne by codenameone.

the class IOSImplementation method createAlphaMask.

// -------------------------------------------------------------------------
// METHODS FOR DRAWING SHAPES AND TRANSFORMATIONS
// -------------------------------------------------------------------------
/**
 * Creates a platform-specific alpha mask for a shape.  This is used to cache
 * masks in the {@link com.codename1.ui.GeneralPath} class.  On iOS the alpha
 * mask is an OpenGL texture ID (not a raster of alpha pixels), but other platforms
 * may use different representations if they like.
 *
 * <p>The {@link com.codename1.ui.Graphics#drawAlphaMask} method
 * is used to draw a mask on the graphics context and this will ultimately call {@link #drawAlphaMask}
 * which can be platform specific also.
 * </p>
 * @param shape The shape that will have an alpha mask created.
 * @param stroke The stroke settings for stroking the outline of the mask.  Leave null to produce a fill
 * mask.
 * @return The platform specific alpha mask object or null if it is not supported or failed.
 * @see #deleteAlphaMask
 * @see #drawAlphaMask
 * @see #isAlphaMaskSupported
 * @see com.codename1.ui.Graphics#drawAlphaMask
 * @see com.codename1.ui.GeneralPath#getAlphaMask
