How to rotate image?

Audio and Graphics
#1

Using display.newImageRect( …) to display an image but I need to rotate landscape images.  How can I do this?

local bg = display.newImageRect( _G.whichImage, system.TemporaryDirectory, display.contentWidth,display.contentHeight)

Not clear what you mean by ‘rotate landscape image’, but any display object can be rotated by changing the ‘rotation’ field:

bg.rotation = 45 -- rotate to 45 degrees
#3

Thanks for the information!  Yes, this rotates the image.  Now I need to center the image and squeeze the image into the display dimensions.  How can I do this?

#4

Center where, and what dimensions?

Take a look at the display properties.  Maybe that will help.
