# Create a Style for PNG Tiles (/docs/v3/4wings/generate-png)



A Style is a document that defines the visual appearance of a map, in this case the map will be in PNG format, it includes what data to draw, the order to draw it in, and how to style the data when drawing it.

#### Generate PNG [#generate-png]

<OpenAPIPage document="apiv3" operations="[{ path: '/v3/4wings/generate-png', method: 'post' }]" hasHead="false" />

Examples using **AIS apparent fishing effort**:

* [EXAMPLE 1](/docs/examples/generate-png/png-example1) - Filtering by time period
* [EXAMPLE 2](/docs/examples/generate-png/png-example2) - Filtering by time period and gear type. Check *Gear Types supported* [here.](/docs/v3/general-api-doc/reference-data)

Examples using **SAR (Synthetic-aperture radar) vessel detections**:

* [EXAMPLE 3](/docs/examples/generate-png/png-example3) - Filtering any SAR vessel detections by time period
* [EXAMPLE 4](/docs/examples/generate-png/png-example4) - Filtering SAR vessel detections that didn't match with AIS vessels

Examples using **AIS Vessel Presence**:

* [EXAMPLE 5](/docs/examples/generate-png/png-example5) - Filtering by time period for all vessel types
* [EXAMPLE 6](/docs/examples/generate-png/png-example6) - Filtering by vessel type (cargo and carrier vessels)
