Properties
- compressionQuality → double
-
The compression quality of the tile images. The compression quality
controls how much loss the image will be subjected to by the compression
algorithm. The values of the pixels of an image compressed with a higher
compression quality will be closer to those of the original image. The
valid range of compression quality values is from 0 to 100.
