DM6437中VPFE的缩放器输出图像的大小是由限制的么？实际发现宽度必须是16的整数倍，请求确认。

• Vertical and horizontal resize ratio values (RSZ_CNT.VRSZ and RSZ_CNT.HRSZ) should be within

the range: 64 to 1024.

• Output Width:

– Should be within the maximum limit:

• width < 1280 (if vertical resize value is in the range: RSZ_CNT.VRSZ = 64 to 512)

• width < 640 (if vertical resize value is in the range: RSZ_CNT.VRSZ = 513 to 1024)

– Should be even

– Should be a multiple of 16 bytes (for vertical upsizing)
