Curls using rectangle from center of image, alpha insertion on

The Page Curl operator can create page curls anywhere on an image. Generally speaking, you probably want to use the Rectangle or Entire Image area selection tools to make the area selection, other tools may give odd results as they mask off part of the effect, which is most decidedly "squarish."

Page Curl Controls

Trends

Some of the controls have a Trend button next to them. These trend buttons allow you to set variables over a series of frames. Each frame of any animation may be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Trend graphs have equidistantly spaced vertical lines. For animations under 100 frames in length, each of these lines represents a frame in the animation. The number of frames in any one sequence can be altered using the Sequence controls item from the Timeline pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames.

Transparency

This allows you to set how transparent the curled region is. When transparent, the image underneath begins to show through, as if the page were a semi-transparent sheet of acetate.

Active Corner

This controls which corner of the area selection the curl will be rendered.

Shadow

This controls whether a shadow will be rendered.

Vertical Priority

This controls which of the possible two sides of the selected corner the curl is rendered from.

Exposure

This is the color of the area exposed by the curl (unless Alpha is checked)

Highlight

This is the color of the highlight on the curl surface.

Alpha

If this is checked, instead of rendering the Exposure color into the exposed area, the exposed area will be made transparent.

Tip: Alpha insertion in the Page Curl operator acting "funny"? Probably what's going on is that the image doesn't actually have an alpha channel. The fix is simple: Make one, using the Make Alpha operator. Set it for "Replace Entire Alpha Channel" and use the "Entire Image" tool to create it. Then come back and make your page curl. That should do it!
