In this work sheet, we zoom 3 items: 1. The "Persian Carpet" is simply computed and zoomed as is. 2. "Damier" [Chess board], will create a default file, C:\SmathFile, that you manage otherwise. It will demonstrate DownSampling and fraction DownSampling. 3. "Tea Pot" image, you will have to install yourself for testing integer upsampling, down sampling, fractional. DownSampling is often useful from web screen capture, mostly Edu. stuff .... Jean  Image Zoom Express.sm (82kb) downloaded 30 time(s).
