Types

type Configurations

type Configurations struct {
	Height        int    `json:"height"`           // Initial image height
	Width         int    `json:"width"`            // Initial image width
	OptimizedSize bool   `json:"optimized_size"`   // Reduces the image dimension if possible.
	CutForMaxZoom bool   `json:"cut_for_max_zoom"` // Cuts object into smaller ones to archive max zoom if needed. Every feature is also applied on the sub images
	Clipping      bool   `json:"clipping"`         // Clips the image
	MapType       string `json:"map_type"`         // Map type for image generation
