I always thought that shadows were possible to do in PDF (after all TikZ does it using some type of PDF primitives).
It is. I use MetaPost to draw the shadows using the shading mechanism:
withshading("circular", urcorner bottom_left, urcorner bottom_left, radius, 0) withfromshadecolor \MPcolor{c:transparent} withtoshadecolor col;
Don't mix Type2/3 with Type 4/5 shadings (see my answer to Aditya). They are all called 'shadings', but only the latter can be used for the creation of realistic looking drop shadows.
Thanks for pointing that out. I will have a look into my code again.
I was (and actually I still am) confused by the different shading methods provided by MetaFun. I admit that I never read the PDF reference which means that I don't know the shading internals. I experimented a little and came up with a working solution to add some eye-candy to presentations.
Nearly everyone loves eye-candy in presentations. It distracts the observer from the question "What am I doing here....?" ;-)
And to repeat myself: there is nothing wrong with bitmaps.
I agree. Even Knuth designed his fonts as bitmaps (at least the output is a bitmap). However, bitmaps always have a fixed size and thus are not scalable.
True. I haven't played around with Photoshop or Indesign for years, but the old versions also used bitmaps for their drop shadows. If Adobe as the inventor of PDF does it, ...
Take the best from both worlds ;-)
ACK
And thanks for this nice module and especially for the well-written documentation.
I tried my best (which means it took a looooooooooooong time). :-)
