Why does canvas.NewImageFromFile() not load the image from the file system?

[srackham]

It just sets the file name:

fyne/canvas/image.go

Lines 195 to 198 in dc34dad

	func NewImageFromFile(file string) *Image {
	return &Image{File: file}
	}

Setting up an image just makes sure that the the data is available for the renderer to read the data (like FromReader or FromResource just sets up a resource in memory).

It's not until later that the image is decoded and rendered.

Thanks for clearing that up, I was playing with manually scaling and loading in-memory thumbnails (p.103 of your excellent Building Cross-Platform GUI Applications with Fyne book) and I had completely forgotten that URI-based images are rendered auto-magically.
