Not So Easy Technical Question

[handrawn]

this trick also works for transparent background raster line art - I 've used it to darken the imported line art, grouped the clones and then made a bitmap copy for tracing

the darker bitmap copy usually traces better and for bw art its quicker and easier to clone than play with the photo tool or transparency

[all the art/copy at 300/600 dpi]

@Phil - good explanation - thanks

The downside of placing lots of copies on top of each other is that you'll start to see jaggy edges. But that's less of a problem at high resolution.

aye hence the use of 300/600 dpi

and to be fair the bitmap tracing in xara tends to result in jaggy edges on the vector lineart when tracing in greyscale [photgraphic tracing produces way too many shapes] - the smoothing function is somewhat heavy-handed and so often the lesser of two evils is the jaggies - high enough resolution and they are insignificant for what I do

UPDATE*

I have experimented with this a bit and it seems you pretty much will need two clones of the original vector art on top of the vector image. This consistently works best.
