Instead the smallest one used that gives similar impression to the harvested original tiles. This setting is 93. 4:2:0 subsampling and integer DCT-method used, as guessed by Gimp. Signal chain: Harvested tiles from source at Raremaps → stitched with jpegtran → doublings removed with Gimp and mentioned Python script → saved as JPEG. Exception: "Tilted L", constituted by topmost and leftmost 253 pixels, are... |

Sie mussten um drei Pixel nach unten bzw. rechts verschoben werden, wodurch diese Kacheln nicht verlustlos in diese Grafik eingefügt werden konnten. Die Originaldaten dieser verlustbehafteten Bearbeitungen folgen mit dieser und den folgenden beiden Versionen: Erst die obere linke Ecke, dann die obere Zeile, dann die linke Spalte. Dann kommt das komplette Bild (am Rand nicht, aber im Wesentlichen doc... | |
