Loading an Image : syntax: display.newImage( filename [, baseDirectory] [, left, top] ) example: newImage = display.newImage( "image.png", 10, 20 ) myImage2 = display.newImage( "image.png" ) Image Autoscaling: The default behavior of display.newImage() is to auto-scale large images.To control manually we can use boolean value. syntax: display.newImage( [parentGroup,] filename [, baseDirectory] [, x, y] [,isFullResolution] ) example: newImage = display.newImage( "image.png", 10, 20, true ) Images with Dynamic Resolution : syntax: display.newImageRect( [parentGroup,] filename [, baseDirectory] w,h ) example: newImage = display.newImageRect( "Image.png", 100, 100 )
