3.1.16.2 Write Parameters

Figure 3-20 describes the command parameters.

Figure 3-20 Write Parameters

MSB	Byte 1						LSB
b7	b6	b5	b4	b3	b2	b1	b0

b(7:3)	Reserved
b(2)	Short axis image flip: 0: Image not flipped. 1: Image flipped.
b(1)	Long axis image flip: 0: Image not flipped. 1: Image flipped.
b(0)	Image rotation (for portrait source only): 0: No rotation 1: Minus 90° rotation

Figure 3-21 shows the result of non-rotation and rotation of a portrait source. If a portrait image is not rotated, it is centered and padded with black bars.

Figure 3-21 Rotation and Non-Rotation of Portrait Source

Landscape images typically must not be rotated, but the system allows this as it may be appropriate for some situations or configurations. The user is responsible for determining if the result is acceptable.

Image rotation is allowed while keystone correction is enabled, though it may not be appropriate for all situations or configurations. The user is responsible for determining if the result is acceptable.

Figure 3-22 Long-Axis Flip

Figure 3-23 shows the short-axis flip.

Figure 3-23 Short-Axis Flip

Note: Image Rotation is not supported on the DLPC3420 nor the DLPC3421
