25 | The main purpose of OptiPNG is to *optimize* PNG files, i.e. to reduce | |
26 | their size to a minimum, without losing any information. In order to | |
27 | achieve this goal, OptiPNG performs the following tasks: | |
28 | ||
29 | - It losslessly reduces the bit depth, the color type and the color | |
30 | palette of the image. This step reduces the size of the uncompressed | |
31 | image, which, indirectly, reduces the size of the compressed image | |
32 | (i.e. the size of the PNG file). | |
33 | ||
34 | - It runs a suite of compression methods and strategies, and selects | |
35 | the compression parameters that yield the smallest output file. | |

38 | Głównym zadaniem OptiPNG jest optymalizacja plików PNG, tzn. | |
ee71da82 | 39 | zmniejszenie ich rozmiaru do minimum bez straty jakichkolwiek |
1e8988ee | 40 | informacji. Aby osiągnąć ten cel stosuje się: |
ee71da82 | 41 | |
1e8988ee | 42 | - Bezstratną redukcję głębi kolorów, typu koloru i palety kolorów. Ten |
34d1c0b5 | 43 | krok zmniejsza rozmiar nieskompresowanego obrazu, przez co zmniejsza |
9c6befc7 JB |
44 | się również rozmiar skompresowanego obrazu (czyli wielkość pliku |
45 | PNG). | |
ee71da82 | 46 | |
1e8988ee JR |
47 | - Porównuje się wyniki działania różnych metod i strategii kompresji w |
48 | celu wyboru takich parametrów, które dają najmniejszy rozmiar pliku | |
ee71da82 | 49 | wynikowego. |
