touchgfx::SnapshotWidget class
@class SnapshotWidget SnapshotWidget.hpp touchgfx/widgets/SnapshotWidget.hpp A widget that is able to make a snapshot of the area the SnapshotWidget covers. A widget that is able to make a snapshot of the area the SnapshotWidget covers. The SnapshotWidget will show the snapshot captured when it is drawn. Note: The snapshot must be taken from a byte aligned position. On BPP=4, this means on even positions, x=0, 2, 4, 8,... On BPP=2, this means on positions, x= 0, 4, 8, 12,... On BPP=1, this means on positions, x= 0, 8, 16,... @see Widget
