IMWRITE_PNG_STRATEGY_DEFAULT Python: cv.IMWRITE_PNG_STRATEGY_DEFAULT
| Use this value for normal data. |
IMWRITE_PNG_STRATEGY_FILTERED Python: cv.IMWRITE_PNG_STRATEGY_FILTERED
| Use this value for data produced by a filter (or predictor).Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. |
IMWRITE_PNG_STRATEGY_HUFFMAN_ONLY Python: cv.IMWRITE_PNG_STRATEGY_HUFFMAN_ONLY
| Use this value to force Huffman encoding only (no string match). |
IMWRITE_PNG_STRATEGY_RLE Python: cv.IMWRITE_PNG_STRATEGY_RLE
| Use this value to limit match distances to one (run-length encoding). |
IMWRITE_PNG_STRATEGY_FIXED Python: cv.IMWRITE_PNG_STRATEGY_FIXED
| Using this value prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications. |
