Tools For ProShow (Update)

ProShow has considerable capability to which Photodex does not provide direct access. That is the domain of the expert, according to Photodex. So, if you want to access that capability, if you even know it exists, you are on your own. Tools For ProShow provide access to much of that capability. ProShow’s cropping tool is minimalistic. Its outlining capabilities are very limited and have not changed much since the program was first introduced. The rotate center function, first introduced in version 4, was meant to allow the rotation of a layer on something other than layer center. Photodex’s implementation provided access to points only within the layer boundaries. First introduced around mid-April 2010, the function has not changed since then. The program doesn’t tell you how wide or tall your layer is. That is something you must figure out for yourself, if you know how. When you rotate a layer on a rotate center value, ProShow does not tell you where that layer really is. The layer’s pan setting is based on where the layer’s center is … unless the layer is rotated off around a point that is different than layer center. The result is a misreported layer position. Sometimes it’s important to know exactly where that rotated layer is located.

Tools for ProShow addresses all of these issues and then some. When first introduced, there were only 9 tools in the toolkit. Now, there are over 25 different tools. Many of the tools are usable in both ProShow Gold and Producer. Only those tools related to modifiers or the case where a change in zoom occurs in each axis are not applicable. In fact, the Layer: Outlines/Frames tool provides the means to use graphics as outline layers similar to what Producer can do natively. It also gives tools to create a graphic that works as a frame. The outlining capability within Gold is next to useless.

I released a new version near the end of June. That was v11.21. I continued making various changes. 88 changes later, v11.33a was released. Some of the changes were cosmetic. Others were a re-working of the equations to provide more accurate information over a more diverse range of settings. For others, the tools were enhanced, becoming more robust. Many changes were under the hood changes.

A new tool was provided to tell how much space is to each side of a layer.

The Layer Outlines/Frames was significantly reworked. It should prove easier to use and understand. The Cropping tool was enhanced slightly. The Findings tools of Cover Layer during Rotation and Largest Width during rotation were reworked considerably. They now work for all scales and layer aspects. The Width & Height, Zoom tool was enhanced slightly.

Each layer has an angle that provides the widest presentation on the screen. This information depends upon the layer’s aspect. That information is now provided in the Layer: Aspect/Dimensions section and the Layer: Outlines/Frames tools. You never know when that information might prove helpful.

I hope you find the toolkit found in Tools For ProShow useful.

Modifier Zoom

Modifiers were first introduced in ProShow Producer v4. Photodex has yet to improve them as of v8. It has been left up to the so-called “expert” ProShow user to figure out how to use them. One of the modifiers deals with a layer’s zoom setting. This modifier alters a layer’s zoom based on the layer’s existing zoom setting. It is entered as a constant value on the layer’s zoom setting.

A cursory review reveals that this constant value represents the percent of change of the layer’s existing zoom setting that is added to the layer’s zoom setting. So, if the layer has a zoom of 100 and a constant value modifier of 10 is assigned to the layer, when the layer is played, the layer will display as 110. If the modifier was -10, the layer would display as 90.

I’ve been using modifiers for years. I do not, however, use zoom modifiers all that often. But, too, I’ve only been making cursory changes using them. My main use has, in the past, been to periodically apply the modifiers to a layer to create appearance of an outline for another layer. These have been related to small changes in size.

I developed a tool in my TOOLS FOR PROSHOW that is used to define size changes to a layer to allow it to work as an outline or frame to another layer. It defines the size changes necessary in terms of zoom settings, zoom settings and modifier values, or a dimensioned layer of a specific and size. But, it was limited in utility to the specific task of frames or outlines. I wanted something that gave me more latitude. So, I created a tool, MODIFIER ZOOM that would help me create a modifier for zoom.

When creating a zoom modifier there are three attributes that are dealt with: a layer’s starting zoom, the final zoom value, and the modifier itself. But, knowing any two of these three values lets you calculate the missing value. Sometimes you want to know what value of modifier is required for a given setting of zoom that provides a desired zoom setting. But, likewise, you may know what the layer’s zoom setting and what its zoom modifier are. What you want to know then, is what the final zoom setting will result from that pair. Other times, you may want to know what the required starting value of zoom is for a given end zoom value and a specific modifier. So, that’s how I built the tool. Choose whether you want to know the start zoom, end zoom, or modifier … the tool will then ask for the values it needs to calculate the values being sought.

The tool was built on the idea that the modifier created a proportional change in the zoom of that layer. What I discovered, however, was that Photodex didn’t build the modifier zoom function that way. In the process of testing the tool, I discovered that the layer’s zoom settings were cross-related. The starting zoom value of one axis had an effect upon the modifier calculation of the other axis.

Equation 1. X-Axis Modifier

modifier-equation-y-axis

Equation 2. Y-Axis Modifier

Where Xe and Ye are the End value of Zoom for the X and Y axis respectively. Xs and Ys represents the initial (or Start) value of zoom for the X and Y axis respectively. Finally, Mx and My are the Modifier values for each axis (X and Y axis respectively). That’s all there is too it. However, note that while the percent change from the starting zoom has been understood for some time no, the idea that the other axis could affect the actual modifier value for current axis was unknown. Photodex has NOT documented any information about modifiers. This particular quirk of zoom modifiers was a big surprise.

Tools For ProShow (Update)

For the past few months I’ve been working on my Tools for ProShow on and off. As I was doing this, one change, improvement, or tweak led to another. All in all, the Tools for ProShow are an even more useful tool than they were previously for those wanting to take advantage of capabilities within ProShow that Photodex does not provide to its customers. For those of you who don’t know it, ProShow has considerable capability that Photodex hasn’t provided a framework that allows you to take advantage of it. Its cropping feature is weak. Its outline and shadow creation features are poor. Its Rotate Center feature has a very limited implementation of what it’s capable of doing. Right now, as long as you keep the Rotate Center values within the boundaries of the layer, you can make somewhat effective use of the feature. However, that does not mean you can specify your own rotation location on the screen … just within the layer’s boundaries. ProShow tells you little about a layer’s width and height. This is information that could be helpful in proper positioning of your layers on or off of the slide. ProShow does not document its modifiers or the functions that the modifiers use. While I don’t either, at least I provide the means to effectively use the Quadratic Curve and Linear Ramp functions. Captions or the Text on Text Layers use a different positioning method than layers use. Specific positioning of the text relative to a layer can prove confusing, if not daunting, if accuracy in positioning is important. ProShow provides no bridge between the two. ProShow provides you with timing information but provides no means to determine time between various points within the slideshow. This is all addressed in the Tools for ProShow … and then some.

Tools for ProShow is an Excel Worksheet that performs calculations that let you do things in ProShow once thought impossible, very difficult, or labor intensive. These tools started their life when I first discovered the relationships between Pan, Zoom, and Rotate Center in June 2011.

 Tools For ProShow Enhancements/Changes.


The Tools worksheet has been updated. It has a release version of 10.15e. Extensive revisions, enhancements, or tweaks of many of the tools has occurred since the last update.

The Equal Size Changes tool was renamed LAYER: Outlines/Frames. This tool was extensively revised. The tool is used to create the appearance of an outline or frame around another layer. One enhancement was the ability to specify the width of the outline on each layer’s side. This width is applied to each layer’s side. A second enhancement was that the layer’s aspect is now selected from a dropdown list of defined aspects as well the three original layers given in the Layer Information tool. A third enhancement was the ability to give the layer a Polaroid outline. That is, equal sized outline widths on three sides and a very wide outline width on the fourth side. A fourth enhancement was that the number of modifier-based zoom changes was changed from three to six. A fifth enhancement involved the Aspect, Effective section. A user defined Aspect, Effective End layer was included. This extends this tool’s usefulness to ProShow Gold. With the ability to use a layer with a size specified by the user, cropping or editing it in a graphical editor becomes even easier than previously possible.

Findings: Calculated Settings. The calculations for the layer zoom and width were extensively revised for improved speed and reduced resources. A few calculation errors related to the safe zone were also corrected.

Findings: Formulae. Removed. In its place were two new tools: Largest Width During Rotation and Cover Layer During Rotation.

The Largest Width During Rotation calculates the largest width of the layer during its rotation at the currently entered zoom setting.

The Cover Layer During Rotation gives the required zoom setting of the current layer to cover a layer of its given zoom setting during a rotation.

Layer Support Information. Removed. In its place are the new tools Width & Height and Modifier Zoom.

Numerous minor data arrangements within various tools were also made.

OVERVIEW


 The Tools for ProShow include the following:

1)  Cropping Tool. Obtain cropping dimensions for a layer for a specific aspect. A sophisticated too that far exceeds the limited capabilities of the ProShow cropping feature.. PSG/PSP.

2)  Distances. Move a layer along the line of an angle of rotation for a specified distance or along a line perpendicular to that angle of rotation for a specified distance. PSG/PSP.

3)  Find Halfway Point. Find the slide location point located halfway between two layers given their Starting and Ending locations (X-Axis and Y-Axis). PSG/PSP.

4)  Findings. Exploits the relationships between pan, zoom, and rotate center, layer width and height. PSG/PSP. Note that PSG zoom values are always the same for each axis.

  1. Align Here. Position a layer’s side, corner, or center to a specific screen location.
  2. Calculated Settings. Pan, Zoom, and Rotate Center functions are interrelated. So, when two function values are known, deriving the missing function’s value is possible. This section calculates the value of the unknown function.
  3. Cover Layer During Rotation. Sometimes you will want to rotate a layer over the top of another, completely obscuring it from view. This tool provides information to do just that It gives the minimum zoom values necessary to cover the layer and what its width is while it is doing that.
  4. Layer Width and Height. ProShow provides no layer width or height information directly. You must make some assumptions or a bit of math if you need that information. This section provides this information. (NEW)
  5. Largest Width During Rotation. Sometimes you need to know what the largest width of a layer is when rotated at a given zoom setting. This tool provides that information. (NEW)
  6. Locations. This gives the screen location of a layer, its side, or its corner. This information is provided for a given Rotation on some portion of the layer.
  7. ProShow Settings. Layer values from ProShow layer settings.

5) Layer Information. This provides the slideshow’s layer information. There are three layers provided in this section. The section provides each of the three ProsShow Layers with dimensions (to identify the layer’s aspect) and associated scale. This tool’s information is also used by other tools: Findings, Cropping, Width & Height, Distances, Proportional Sizing and Placement: Layer 4, Layer: Outlines and Frames, Slide Information. PSG/PSP.

6)  Layer: Outlines/Frames. This tool gives settings required of a layer to give another layer the appearance of an outline. An outline typically has an equal size on each side of the layer. It also gives settings for an outline that creates the look of a Polaroid Photo (a larger outline section either at the layer top or bottom than on the other two sides). The tool provides zoom and modifier settings for creating a size change via the zoom feature versus changing the layer’s zoom directly. There is also a section that gives settings that allow a layer size change via cropping, a graphic editor, or the ProShow create Layer (Solid/Gradient) feature: Frame Creation Helper (for Bitmap Editors). This feature allows the creation of an outline or frame layer within ProShow Gold.   Cropping of an existing layer or creating a graphic of a specific aspect for use in PSG may be required to achieve results that are otherwise only possible from within PSP. PSG/PSP.

7)  Modifier Rotation Calculation. Find the rotation value in terms of degrees, phase change, or modifier value. Modifiers make rotation changes in terms of a percent of a rotation. This tool makes choosing the appropriate rotation amount easy. PSP

8)  Modifier Zoom. This tool calculates the missing value when given two of three values: Starting Zoom, Ending Zoom, and Modifier. This tool works for either a layer’s single axis or both axes. PSP. (NEW)

9)  Position a Rotated Layer. Given a starting and final location, this tool gives the distance a layer has moved. When Desired Final Position is provided (for a layer that has been tilted — either vertical or horizontal) or rotated, the layer’s pan settings to position the layer at that desired location are provided. PSG/PSP.

10) Proportional Sizing and Placement: Layer 4. This tool is useful for creating a layer that is proportional in size and location to another layer. PSG/PSP.

11)  Quadratic/Linear Function. This section provides answers for the ProShow modifier functions of Quadratic Curve and Linear Ramp. The quadratic curve uses an equation that defines a parabola. The ProShow factors define a region of that curve to position a layer. When the Quadratic Curve’s first factor (the quadratic factor) is set to zero, the effective equation defines the Linear Ramp. A linear equation defines a sloped line (which can also be defined as “ramp”). PSP.

12)  Slide Information. This provides the slideshow’s Frame Aspect and the Safe Zone size. This information is used by other Tools For ProShow tools: Layer Information, Findings, Width & Height, Distances, Proportional Sizing and Placement: Layer 4, Layer: Outlines and Frames. PSG/PSP.

13)  Time: Show/Slide/Keyframe. Giving a Starting time (minutes and seconds) and a Final (or ending) time, a difference in time is calculated. Some modifier functions have the ability to start at the following three locations: Show, Slide, or Keyframe. As it can be important to know the actual start time at any given location because of the function used and it’s value at that time can be calculated. PSG/PSP. Usefulness within PSG is very limited.

14)  Text Layer Text Positioning. Captions use a different positioning system than Layers do. Text layers are layers on which captions have been placed. As such, they have the benefits and characteristics of both Layers and Captions. A text layer caption is positioned on the layer using caption positioning. The text layer is positioned as a layer is positioned. Therefore, the actual position of that text might need some calculation. This tool provides that information to give TEXT POSITION or SCREEN POSITION. To get text position, the Layer Pan value and the desired Screen location are needed. To get the screen position, the Layer Pan and the Text Position information is needed. PSP.

15)  USER Calculations. This section allows you to make calculations or use the contents of results found within the worksheet to create other calculations you can use for a variety of purposes. PSG/PSP.

16)  Width & Height.  This tool asks for the following information: frame aspect, layer aspect, and layer scale.  If the zoom is provided, the tool calculates the width and/or height. If the width and/or height is provided, the associated zoom value is provided. This can be helpful when dealing with v8’s text region that you want constrained to a specific size and/or aspect. PSG/PSP. (NEW)
