Functions

func ToFyneCoordinate

func ToFyneCoordinate(c fyne.Canvas, v int) float32

ToFyneCoordinate converts a screen coordinate for a given canvas to a fyne coordinate

func ToFyneSize

func ToFyneSize(obj fyne.CanvasObject, width, height int) fyne.Size

ToFyneSize returns the scaled size of an object based on pixel coordinates, typically for images. This method will attempt to find the canvas for an object to get its scale. In the event that this fails it will assume a 1:1 mapping (scale=1 or low DPI display).

func ToScreenCoordinate

func ToScreenCoordinate(c fyne.Canvas, v float32) int

ToScreenCoordinate converts a fyne coordinate in the given canvas to a screen coordinate
