| * FUNCTION |
| * mlib_ImageAffineEdgeZero - implementation of MLIB_EDGE_DST_FILL_ZERO |
| * edge condition |
| * mlib_ImageAffineEdgeNearest - implementation of MLIB_EDGE_OP_NEAREST |
| * edge condition |
| * void mlib_ImageAffineEdgeExtend_BL - implementation of MLIB_EDGE_SRC_EXTEND |
| * edge condition for MLIB_BILINEAR filter |
| * void mlib_ImageAffineEdgeExtend_BC - implementation of MLIB_EDGE_SRC_EXTEND |

| * void mlib_ImageAffineEdgeExtend_BC2 - implementation of MLIB_EDGE_SRC_EXTEND |
| * edge condition for MLIB_BICUBIC2 filter |
| * |
| * DESCRIPTION |
| * mlib_ImageAffineEdgeZero: |
| * This function fills the edge pixels (i.e. thouse one which can not |
| * be interpolated with given resampling filter because their prototypes |
| * in the source image lie too close to the border) in the destination |
| * image with zeroes. |
| * |
| * mlib_ImageAffineEdgeNearest: |
| * This function fills the edge pixels (i.e. thouse one which can not |
| * be interpolated with given resampling filter because their prototypes |
| * in the source image lie too close to the border) in the destination |
| * image according to the nearest neighbour interpolation. |
| * |
| * mlib_ImageAffineEdgeExtend_BL: |
| * This function fills the edge pixels (i.e. thouse one which can not |
| * be interpolated with given resampling filter because their prototypes |
| * in the source image lie too close to the border) in the destination |
| * image according to the bilinear interpolation with border pixels extend |
| * of source image. |
| * |
| * mlib_ImageAffineEdgeExtend_BC: |
| * This function fills the edge pixels (i.e. thouse one which can not |
| * be interpolated with given resampling filter because their prototypes |
| * in the source image lie too close to the border) in the destination |
| * image according to the bicubic interpolation with border pixels extend |
| * of source image. |
| * |
| * mlib_ImageAffineEdgeExtend_BC2: |
| * This function fills the edge pixels (i.e. thouse one which can not |
| * be interpolated with given resampling filter because their prototypes |
| * in the source image lie too close to the border) in the destination |
| * image according to the bicubic2 interpolation with border pixels extend |
| * of source image. |
