Browser scaling quality
Browsers have traditionally competed in having the most primitive and poor image scaling algorithms you could imagine. On this page you can test the scaling quality of your browser. On the screen the images should appear almost the same. If the circle is drawn in a broken line, the browser didn't do a good job scaling down. When printed out, the right-side circle should be more clear and sharp and pretty looking than the left-side image.
Pre-scaled:
|
This image has been pre-scaled down to 50x50 pixels using a proper scaling algorithm.
The disadvantage is that the original clarity cannot be restored.
|
Scaled by browser:
|
This image is scaled down to the proper size by the browser.
When printing you should see the full resolution (the circle becomes more sharp).
Some browsers will scale the image down before upscaling it to printer resolution, which is just plain stupid.
