BottomPattern

Specifies the pattern of a three-D object's lowered edge. Syntax:

```
set the bottomPattern of <object> to {empty | <patternNumber> | <imageID>}

```

Examples:

```
set the bottomPattern of scrollbar 2 to 4934

```

```
set the bottomPattern of button "OK" to savedPattern

```

Objects whose threeD property is set to true appear to stick out of or
recede into the screen. Use the **bottomPattern** property to specify
the color of the shadowed edge of the object(glossary).

Pattern images can be color or black-and-white.

To be used as a pattern on Mac OS, an image must be 128x128 pixels or less, and both its
height and width must be a power of 2. To be used on Windows and
Linux, height and width must be divisible by 8. To
be used as a fully cross-platform pattern, both an image's dimensions
should be one of 8, 16, 32, 64, or 128.

The **bottomPattern** of controls is drawn starting at
the control upper right corner: if the
control is moved, the pattern does not shift.

Setting the **bottomPattern** of an object to empty allows the
**bottomPattern** of the object owner to show through. Use
the **effective** to find out what pattern is used for the
object, even if its own **bottomPattern** is empty.

If the object's showBorder property is false, the **bottomPattern** has
no effect.

The setting of the **bottomPattern** property has different effects,
depending on the object type:

* The **bottomPattern** of a stack determines the **bottomPattern** of each object in the stack that does not have its own **bottomPattern**.
* The **bottomPattern** of a card or group determines the pattern of the border around the card or group, as well as determining the **bottomPattern** of each object in the card or group that does not have its own **bottomPattern**.
* The **bottomPattern** of a button forms a border on the bottom and right edges of the button. If the button"s threeD property is false, the **bottomPattern** has no effect.
* The **bottomPattern** of a field forms a border on the top and left edges of the field and (if the field is a scrolling field) the bottom and right edges of the arrow boxes at the ends of the scrollbar and the top and left edges of the scroll area. The field **bottomPattern** also determines the pattern of the bottom and right edges of any text in the field whose textStyle is set to "threeDBox". If the field's threeD property is false, the field border is not affected.
* The **bottomPattern** of a scrollbar forms a border on the bottom and right edges of the arrow boxes at the ends of the scrollbar, and the top and left edges of the scroll area.
* The **bottomPattern** of a graphic, audio clip, video clip, or image has no effect.
* The **bottomPattern** of a player or EPS objects forms a border on the top and left edges of the object. If the object threeD property is false, the **bottomPattern** has no effect.

If an object's **bottomPattern** is set, the pattern is shown instead of
the color specified by the bottomColor.
