Background image for labels

You can use a stretchable image as a background for a label on the map. This allows you to create a distinctive background for labels of arbitrary length or for multi-line labels.

Example of labels with background images

To stretch an image properly, you need to specify monotonous image areas, which can be distorted unnoticeably. These areas will be stretched so that the image size corresponds with the label size. In the image below, blue areas indicate horizontal stretch zones and pink areas indicate vertical stretch zones:

The label background is created from an SVG image. You can add your own image or use an existing style icon.

Note

To stretch a texture in width and height independently, some browsers (for example, Firefox) require the SVG image to contain the preserveAspectRatio attribute set to none.

  1. Open the Style Editor.

  2. Open the Icons menu and select Upload icons -> Select files.
