Dogear
It is possible to create documents with folded over corners,
called “dog ears&rdquo' There are two functions
involved. The first isdogear_lower to create the main
body of the document with the dogear gone, and the second is
dogear_upper to create the corner folded over. The reason
it comes in two parts is that thay you can layer the dogear over the contents over the lower portion,
in case part of the contents is covered by the dogear.
This example constructs a 90x128 icon (because 1:sqrt(2) is
the proportions of a A4 page). In this case our
“base” document is antique white, you will probably
want something spiffier for your icon theme. First the lower
layer:
icomp '
page = crop(AntiqueWhite, 90, 128);
dogear_lower( |
page |
, 5, 8)' -o |

 |
|
And now the upper layer
icomp '
page = crop(AntiqueWhite, 90, 128);
dogear_upper( |
page |
* 0.9, 5, 8)' -o |

|
|
|
We make the back slightly farker (that's the 0.9 multiply you
see) so there is a touch of contrast between the back and the
front. You could use a different technique, such as a
contrasting broder, instead. Finally, we put it all together
with some content:
icomp '
page = crop(AntiqueWhite, 90, 128);
l3 = dogear_lower(page, 5, 8);
l2 = scale_within(
|

|
, l3);
l1 = dogear_upper(page * 0.9, 5, 8);
l1 over (l2 over center l3)'
-o |

You can change the proportions of the dogear by changing the
radius and tag arguemnts. It is important that the
radius and tag arguments to the two dogear
functions. The image arguments need to be closely
related, as well. If you want the dogear on the other side,
use the hflip function.
