Scale by a factor of 3 a row of pixels of 16 bits.
This function operates like scale3x_8_def() but for 16 bits pixels.
- Parameters:
-
src0 | Pointer at the first pixel of the previous row. |
src1 | Pointer at the first pixel of the current row. |
src2 | Pointer at the first pixel of the next row. |
count | Length in pixels of the src0, src1 and src2 rows. It must be at least 2. |
dst0 | First destination row, triple length in pixels. |
dst1 | Second destination row, triple length in pixels. |
dst2 | Third destination row, triple length in pixels. |
Scale by a factor of 3 a row of pixels of 32 bits.
This function operates like scale3x_8_def() but for 32 bits pixels.
- Parameters:
-
src0 | Pointer at the first pixel of the previous row. |
src1 | Pointer at the first pixel of the current row. |
src2 | Pointer at the first pixel of the next row. |
count | Length in pixels of the src0, src1 and src2 rows. It must be at least 2. |
dst0 | First destination row, triple length in pixels. |
dst1 | Second destination row, triple length in pixels. |
dst2 | Third destination row, triple length in pixels. |
Scale by a factor of 3 a row of pixels of 8 bits.
The function is implemented in C. The pixels over the left and right borders are assumed of the same color of the pixels on the border.
- Parameters:
-
src0 | Pointer at the first pixel of the previous row. |
src1 | Pointer at the first pixel of the current row. |
src2 | Pointer at the first pixel of the next row. |
count | Length in pixels of the src0, src1 and src2 rows. It must be at least 2. |
dst0 | First destination row, triple length in pixels. |
dst1 | Second destination row, triple length in pixels. |
dst2 | Third destination row, triple length in pixels. |
