PhotoLine Tip: Vectorize an image |
1. You have an image on a sheet of paper and want to get a vector graphic from it. 2. Although
the image is black/white, you should scan it in gray mode with about 300dpi.
3. Select
now Tool/Curves.... Double click the All curve. You will see
the Curve Editor of PhotoLine.
4. This function
changes the various gray values of the image to only two (black and white.
You can click on the two arrow buttons of the icon bar (left and right)
to move the vertical line. So you can setup the threshold for your convertion.
5. Just try
to get the best position for the vertical line. The best position is where
you get a black and white image without noise pixels and your image is
still complete. If there are some noise pixels left after this operation,
you can remove it with the rubber tool or the median filter.
6. Select
now the function Layer/Convert Layer Type.... Setup the destionation
to vector here. You will get a vector image with many vector points.
7. To get
a vector graphic that can be better handled select Layout/Vector/Optimize
Vector Layer....
8. Depending
on your image, setup to optimize lines or curves and setup the tolerance
value.
