Roll/  Crawl Properties

There are three groups of properties for these objects, similar to the text template: common text attributes; continuity mode and queue options; and dynamic speed properties. The first two are controlled through object-specific toolbars, while the third one can be set in the specially designated dialog box.

Continuity and Queue mode

When a crawl/roll object is selected (single click) the following string appears in the last row of the toolbar: .

 

The gear-wheel  button opens the Embedded Objects list. This is the one already described for text objects. Please, check above in the Manual.

Speed field - controls the speed of dynamic objects, such as animations, crawls, and rolls. Its value can be positive (right-to-left movement) or negative (left-to-right movement). If zero, the object is frozen.

NOTE: You can change the speed interactively at any moment, even when the object is running on-air.

If the value in the Loop field is [0], the object will be displayed endlessly.

The next three buttons  refer to the object’s background continuity mode. The first one means that the background will be displayed only while the text is running. The second one will “glue” the texts one after another, without any space in between. The third button will display the background continuously.

The last two buttons in this toolbar  concern the Queuing functionality. After pressing one of these buttons, X-Pert Graphics will “remember” the changes for background colors and text colors and it will play them one after another, i.e., you will be able to make a queue of color changes (loops). If none of the above buttons is pressed, X-Pert Graphics will show only the latest change. You can choose how to switch between changes (loops) while in play mode:

Use  if you want to display the subsequent loops one by one, i.e., to leave some space between them (empty or with background color, depending on your settings – see the previous paragraph). In addition, use  if you do not want any space between the successive loops in the object. X-Pert Graphics will generate one loop out of all loops in the queue.

Text and Background Properties

You can edit the common text attributes (such as font selection, size, color, blur, shadow, etc.) and background attributes from another object-specific toolbar:

It appears in the last row of the X-Pert Graphics toolbar when you double-click a Roll/Crawl object. Another way to invoke it is by pressing the Property button  (in the second row of the toolbar) while a Crawl/Roll object is selected.

Write the new texts directly in the object!

NOTE: There is no possibility to insert images as background but you can still insert images and OLE objects in the Roll/Crawl objects.

Pressing  invokes the FontDialogEx dialog, which allows you to manage the font of the selected text. Here you can find all the formatting options, as known from other windows-based editing applications:

Use the Fill Effect button and its additional buttons to modify the colors for your text. You can select None for color, Gradient color, or Texture Fill.

If you click on Gradient color from the drop-down list, you can select from 255 levels of graded transparency and a vast variety of colors.

In the Gradient properties dialog, fix the desired settings:

    Choose a Style for the gradient from the drop-down list:

In the square field to the left drag the cursor to change the gradient positioning.

In the rectangle field below, define the gradient colors and their initial points.

Place the plus-sign cursor in the desired position and click. A black triangle will appear in that position to mark the currently selected point. All other marks will become white.

Double-click on the black triangle to invoke the Color setting dialog.

Modify the color for this color-change point at your will and click OK.

Back in the Gradient properties dialog, you can change the position of the point by dragging it. Also, you can add as many color-change points to the gradient, as you like. Finally, click OK.

Pressing  invokes the Paragraph-formatting dialog box, where you can set all paragraph-formatting options:

The two buttons to the right concern the background. Press  to view a transparency background during editing in the preview area.

Text-formatting buttons - font, font size, bold, italics, underlined, text alignment, font color.

Object links buttons.

Push the  button to insert a still picture object link.

Push the  button to insert OLE compatible objects. Use the drop-down list to fix their position within the Roll/Crawl object.

 

(!) TIP: When a Roll, Crawl or Text object is linked to a text file (*.txt or *.rtf), you can insert a still picture in the text – the image will be displayed among the characters, according to the position of its script in the text. Write the following command in the text file:

<BITMAP>[file path of the image file]</BITMAP>

1) Save your image. Let us assume the file name is “logo.bmp” located on D:\
2) Enter the text in a file, for example "Hello, this is a test project".
3) Continue writing the following: <BITMAP>D:\logo.jpg</BITMAP>.
Thus, your text file will be:
Hello, this is a test project <BITMAP>D:\logo.jpg</BITMAP>
It could also be:
Hello, this <BITMAP>D:\logo.jpg</BITMAP> is a test project
or
Hello, this is a <BITMAP>D:\logo.jpg</BITMAP> test project
Every time you edit the text and save the changes, the text on the output will be refreshed.
If you want to change the picture, change the file name and location part in the script (here it is D:\logo.jpg).
If you want to insert an animated *.gif file in the text, write <MOVIE> instead of <BITMAP>. For example:
Hello, this is a test project <MOVIE>D:\smilie.gif</MOVIE>

NOTE: There is no spell-checker implemented in the X-Pert Graphics text objects (roll, crawl, and text template). You can use some external application for spell-checking and then just copy and paste the text into the X-Pert Graphics object.

 

Dynamic Speed Properties

Pushing the Property tools button  while a Roll/Crawl object is selected will open the Dynamic properties dialog box:

This property dialog box allows you to specify different speeds of the Roll’s and Crawl’s movement.

The movement is represented graphically and you can define the speed of each point of the graphics. The horizontal axis of the graphics represents the position of the Crawl/Roll on the screen. The vertical axis represents the speed multiplier (0; 1; 2; etc.) of the default speed, which is set in the main screen (see the Toolbar section above). The zero value means 0x default speed, i.e., the object does not move; one means 1x default speed, i.e., the object moves with the default speed; two means 2x default speed, i.e., the object moves twice as fast as the default speed, etc.

On the top of the graphics, you can see the object’s (Roll/Crawl) text. By moving the mouse pointer over the grid (the blue lines) or by using the arrow keys, you can select the position in the text, where you would like to change the speed. The text section, which will be displayed at the selected “speed change” point, is enclosed in a frame.

By default, the first point is situated at the beginning of the graphics. A new point is added by pressing the Add  button or by double-clicking in the yellow-squared area.

When you select a position to change its speed, a green point will appear in the grid and its properties (Speed and Position) will be displayed in the Point Properties area to the right. The position’s coordinates are also displayed in the status bar.

If you set a speed of ‘0’ for any position, then you will have to define a delay period. This is the period (in seconds), during which the object will remain stopped. The wait-time appears in a red square under the zero-point.

All points are shown in the Point list to the right of the graphics. Their names are [Point #], where the # stands for the sequential number of the point.

The Align buttons  allow for aligning the selected point toward the previous, the next or the first point in the graphics.

The Default speed field shows the default speed, as it is defined in the main X-Pert Graphics window (see the Toolbar section above).

In the Point Properties area, the following properties of the selected point are shown: Speed, Position, and Time (for zero-speed points only).

The Point list shows the list of all “speed change” points in the object.

The Add button  adds a new “speed change” point in the object graphics.

The Delete button  deletes the selected “speed change” point in the object graphics.
