Detailed Description

Image rotate is a generic functionality in image processing. For C implementation, we take the cvGetQuadrangleSubPix function from OpenCV (http://opencv.org/) for reference.

This set of functions implements image rotate with bilinear interpolation algorithm for 8-bit data types.

ne10_img_rotate_rgba_c()

void ne10_img_rotate_rgba_c	(	ne10_uint8_t *	dst,
		ne10_uint32_t *	dst_width,
		ne10_uint32_t *	dst_height,
		ne10_uint8_t *	src,

	)

image resize of 8-bit data.

Returns

none. The function implements image resize

image rotate of 8-bit data.

Parameters

[out]	*dst	point to the destination image
[out]	*dst_width	width of destination image
[out]	*dst_height	height of destination image
[in]	*src	point to the source image
[in]	src_width	width of source image
[in]	src_height	height of source image
[in]	angle	angle of rotate

Returns

none. The function extracts pixels from src at sub-pixel accuracy and stores them to dst
