To create an image, use the
image method in a slot:
Shoes.app do para "Nice, nice, very nice. Busy, busy, busy." image File.join DIR, "../static/shoes-manual-apps.png" end
When you load any image into Green Shoes, it is cached in memory. This means that if you load up many image elements from the same file, it'll only really load the file once.
You can use web URLs directly as well.
Shoes.app do image "http://is.gd/c0mBtb" end
When an image is loaded from the web, it's cached on the hard drive as well as in memory. This prevents a repeat download unless the image has changed. (In case you're wondering: Shoes keeps track of modification times and etags just like a browser would.)
Note: Green Shoes doesn't support the hard drive cache management feature like Red Shoes.
Green Shoes also loads remote images in the background using system threads. So, using remote images will not block Ruby or any intense graphical displays you may have going on.
The full pixel height of the image. Normally, you can just use the height method to figure out how many pixels high the image is. But if you've resized the image or styled it to be larger or something, then
height will return the scaled size.
full_height method gives you the height of image (in pixels) as it was stored in the original file.
The full pixel width of the image. See the full_height method for an explanation of why you might use this method rather than width.
The URL or file name of the image.
Swaps the image with a different one, loaded from a file or URL.
Rotates the Image element by a certain number of
Shoes.app do img = image File.join(DIR, '../samples/cy.png') img.move 200, 200 animate do |i| img.rotate i*10 end end
