Adjust label density

HERE Raster Tile API provides a ppi parameter to render labels and icons in different sizes helping you find the right balance in label and icon size for the screen's resolution.

The following ppi values are available:

PPI Value	Description	Best for
`ppi=100`	Default value that prioritizes a denser display with smaller yet clearer labels and icons. Condenses more information into a limited space.	Smaller, more intricate displays
`ppi=200`	Middle ground for label sizing. Ideal solution when `ppi=100` results in labels that are too small, and `ppi=400` produces labels that are overly large. Ensures optimal readability and precision.	General-purpose use with balanced readability
`ppi=400`	Larger labels and icons that emphasize visibility and clarity. Ensures clearer and more visible details.	Larger screens where details need to be easily discernible

Examples

See the following examples for how to get various label and icon sizes for a 512x512 pixel tile. Try each of the following ppi values on your target display to find the setting that works best for your use case:
