Transparency and blend modes
Half-transparent fills that overlap and mix, and one orange square laid over a blue bar in four different ways of mixing colours.
Cutting out what you draw
A field of stripes shown through two cut-outs: a disc from the nonzero rule, and a frame from the even-odd rule over two nested rectangles.
A cut-out is a window: what is drawn afterwards shows only where the window is open. The same field of stripes is shown here through two of them — a disc, and a frame made of two nested rectangles where only the ring between them lets the stripes through.
The two use the two filling rules the format defines, which is what makes the ring possible at all. Each panel puts its drawing settings aside, states its shape, marks it as the cut-out, fills the stripes, and puts the settings back, so the cut-out lasts no longer than the panel that asked for it.
What this example shows
- The nonzero rule and the even-odd rule, side by side.
- A ring cut out of two nested rectangles.
- The cut-out limited to one panel, by putting the settings aside and back.

Examples near this one
Gradients in a line and in a circle
Gradients in a line and in a circle painted into boxes the page cuts out: a two-colour blend across and another on the diagonal, a circular one whose outer colour is carried out to the corners, and one passing through three colours.
Text and shapes filled with a gradient
A gradient used as the colour something is filled with: a headline whose letters are windows onto a blend of three colours, and a panel filled with a circular one.
Content shown and hidden by layer
One floor plan on four layers a reader shows and hides: the furniture and the dimensions shown, the notes hidden until asked for, and a draft mark that is looked at but never printed.
One drawing, placed many times
One badge built as a drawing and placed eight times, plus once at half size: the file holds the drawing once, however many times it is placed.
One pattern, repeated across whatever it fills
Six panels filled with repeating patterns — bars, dots, a slant got without redrawing the pattern, a brick wall, two patterns crossing, a wider gap — and a logo whose letters are windows onto the bricks.
