func GiantScreenshot ¶

func GiantScreenshot(lvl *level.Level) (image.Image, error)

GiantScreenshot returns a rendered RGBA image of the entire level.

Only one thread should be doing this at a time. A sync.Mutex will cause an error to return if another goroutine is already in the process of generating a screenshot, and you'll have to wait and try later.

func SaveGiantScreenshot ¶

func SaveGiantScreenshot(level *level.Level) (string, error)

SaveGiantScreenshot will take a screenshot and write it to a file on disk, returning the filename relative to ~/.config/doodle/screenshots

func WallpaperToImage ¶

func WallpaperToImage(lvl *level.Level, target *image.RGBA, width, height int) *image.RGBA

WallpaperToImage accurately draws the wallpaper into an Image.

The image is assumed to have a rect of (0,0,width,height) and that width and height are positive. Used for the Giant Screenshot feature.
