FPVP Tools for ProShow

The tools have a number of minor revisions, bug fixes, and feature additions.

  • The previous release only provided for finding a layer’s side, corner, or center when rotated on Rotate. This release expands upon that. The ability to find the actual position of a layer that was rotated on a rotate center was added.
  • The rotation may now use Vertical tilt, Horizontal tilt, or Rotate.
  • The EQUAL SIZE CHANGES tool was completely revamped.
  • A 4th language option was added (“YOURS”). Now, you can translate the given text to whatever you want to change it to, if you so desire. The other language options are English, French, and Russian.
  • The method of selecting a language was made easier to use.
  • Changes to the worksheet were also made to better accommodate language changes (so the columns don’t get really wide).
  • A link to the tutorial is provided directly within the worksheet now too.

This set of tools provides unprecedented access to some of the power ProShow possesses but which is not apparent except to the more Expert users. These tools provide access to features even most ProShow experts do not have. ProShow is not likely to provide access to the features this set of tools provides any time soon. For instance, 1) ProShow does not give you any information as to how tall or wide a layer is (rotated or not). 2) If you want to crop your later to a specific aspect, you must do the math yourself before entering numbers to get the crop. 3) Rotate Center (a feature that ProShow has provided since the release of v4 over 4 years ago) is implemented in a limited fashion. The power of the rotate center is effectively limited to a layer’s corner or side.

If you want easy access to some of that power, these FPVP tools are the answer. They let you do things that would otherwise require modifiers. As noted previously, these tools can let you do things you thought impossible, very difficult, or labor intensive. They can save you a considerable amount of time and effort. In truth, these tools make the difficult extremely easier. I’ve been using variations of these tools for several years now. Now, that power is available to you as well.


ProShow Rotations

INTRO. Understanding the Photodex rotation system is very useful. It means you can choose a rotation direction without a lot of trial and error. Earlier versions of ProShow have always included the Rotate function. It has always represented rotation around the Z-Axis, the one axis we could never use. Since ProShow is a two dimension (2D) program, Photodex had invent a way to simulate a three-dimension (3D) environment. Their answer to that challenge was Tilt, rotation simulation about the X (Tilt-Vertical) and Y (Tilt-Horizontal) axes.

3D Simulation. Tilt simulates a 3D environment by the clever manipulation of a layers’ two sets of outside edges (i.e., top and bottom sides and/or the  left and right sides). If the distance is increased between one side’s two opposing corners and decreased between the opposite sides two opposing corners, movement into and out of the screen is simulated (along the Z-axis). This size contrast of opposing layer sides tricks the brain into seeing a third dimension. That’s because the wider side “appears” closer than the narrower side.

ROTATION DIRECTION.  When it comes to determining the rotation direction about an axis, which direction is associated with positive or negative values (as represented in the associated rotation box for Tilt-Horizontal, Tilt-Vertical, or Rotate)?  The answer is fairly simple but requires a little explanation. To start with, a rotation around an axis is

  • Positive, if rotation is clockwise (to the right),
  • Negative, if rotation is counterclockwise (to the left; also known as anti-clockwise)

An easy way to remember it is to use the Left Hand rule. If you curl the fingers of your left hand and point the thumb pointing toward your face, you will note that the fingers curl in a clockwise direction.


All axes derive from a central point called the “origin.” All axes meet there. Let us assume that the thumb points along the axis in which you are interested. A positive axis direction for the

  • X axis is LEFT,
  • Y axis is UP, and
  • Z axis is OUT of the screen (directly toward you)

So, for positive rotation values, if you point your left thumb

  • UP, the curl of the fingers indicate that the layer will rotate to the left (Tilt-Horizontal)
  • LEFT, the curl of the fingers indicate that the layer will rotate down (Tilt-Vertical)
  • OUT (toward your face), the curl of the fingers indicate that the layer will rotate to the right (Rotate).

The following graphic might help:

TECHNICAL NOTE: Normally, a positive axis is to the right for X, up for Y, and OUT for Z. The representation of these axes might be a little different depending on your application. However, the relative orientation between each axis will remain the same. Photodex experienced a little faux pax that wasn’t discovered until it was too late to change. That’s why the X axis is giving clockwise (positive) rotations on a negative value axis. No big deal as long as things are consistent. But, still good to know.

Here’s another helpful hint when dealing with rotations. If you want to know a layer’s correct orientation for a given set of rotations, consider each rotation type in the following order:

  1. Tilt-Horizontal
  2. Tilt-Vertical
  3. Rotate

Or the following order:

  1. Rotate
  2. Tilt-Vertical
  3. Tilt-Horizontal

Never start out with Tilt-Vertical … it will throw you off every time!

That’s it!
