| * FUNCTION |
| * Image affine transformation with Bicubic filtering |
| * SYNOPSIS |
| * mlib_status mlib_ImageAffine_[u8|s16|u16]_?ch_bc(mlib_s32 *leftEdges, |
| * mlib_s32 *rightEdges, |
| * mlib_s32 *xStarts, |
| * mlib_s32 *yStarts, |
| * mlib_s32 *sides, |
| * mlib_u8 *dstData, |
| * mlib_u8 **lineAddr, |
| * mlib_s32 dstYStride, |
| * mlib_s32 is_affine, |
| * mlib_s32 srcYStride, |
| * mlib_filter filter) |
| * |
| * |
| * ARGUMENTS |
| * leftEdges array[dstHeight] of xLeft coordinates |
| * RightEdges array[dstHeight] of xRight coordinates |
| * xStarts array[dstHeight] of xStart * 65536 coordinates |
| * yStarts array[dstHeight] of yStart * 65536 coordinates |
| * sides output array[4]. sides[0] is yStart, sides[1] is yFinish, |
| * sides[2] is dx * 65536, sides[3] is dy * 65536 |
| * dstData pointer to the first pixel on (yStart - 1) line |
| * lineAddr array[srcHeight] of pointers to the first pixel on |
| * the corresponding lines |
| * dstYStride stride of destination image |
| * is_affine indicator (Affine - GridWarp) |
| * srcYStride stride of source image |
| * filter type of resampling filter |
| * |
| * DESCRIPTION |
| * The functions step along the lines from xLeft to xRight and apply |
| * the bicubic filtering. |
