bufferDepth Property

Retrieves the number of bits per pixel used for colors on the off-screen bitmap buffer.

Syntax

HTML N/A

Scripting [ iBitsPerPixel = ] oClientCaps.bufferDepth

HTML	N/A
Scripting	[ iBitsPerPixel = ] oClientCaps.bufferDepth

Possible Values

iBitsPerPixel Integer that specifies one of the following values:

0 No explicit buffering occurs. The colorDepth property is set to the screen depth.

-1 Buffering occurs at the screen depth. The colorDepth property is set to the screen depth.

1, 4, 8, 15, 16, 24, 32 Off-screen buffering occurs based on the specified number of bits per pixel. The colorDepth property is also set to this value. The value 15 specifies 16 bits per pixel, in which only 15 bits are used in a 5-5-5 layout of red-green-blue (RGB) values.

The property is read-only with a default value of 0.

Remarks

Nonsupported values cause bufferDepth to be set to -1.

When bufferDepth is -1 and the user changes system settings that affect the screen depth, the buffer depth automatically updates to the new depth. This does not occur if bufferDepth is set to a specific value.

Example

This example displays all the properties available through the clientCaps behavior.

Sample Code

<HTML xmlns:IE>
<HEAD>
<STYLE> 
@media all {
   IE\:CLIENTCAPS {behavior:url(#default#clientCaps)}
}
</STYLE>

<SCRIPT>
function window.onload()
{
  sTempStr = "availHeight    = " + oClientCaps.availHeight    + "\n" + 
             "availWidth     = " + oClientCaps.availWidth     + "\n" + 
             "bufferDepth    = " + oClientCaps.bufferDepth    + "\n" +
             "colorDepth     = " + oClientCaps.colorDepth     + "\n" +
             "connectionType = " + oClientCaps.connectionType + "\n" +
             "cookieEnabled  = " + oClientCaps.cookieEnabled  + "\n" +  
             "cpuClass       = " + oClientCaps.cpuClass       + "\n" + 
             "height         = " + oClientCaps.height         + "\n" + 
             "javaEnabled    = " + oClientCaps.javaEnabled    + "\n" + 
             "platform       = " + oClientCaps.platform       + "\n" + 
             "systemLanguage = " + oClientCaps.systemLanguage + "\n" + 
             "userLanguage   = " + oClientCaps.userLanguage   + "\n" + 
             "width          = " + oClientCaps.width          + "\n" ;

  oPre.innerText = sTempStr;

<H1>clientCaps Behavior Sample</H1>

<P>This example shows how to use the new <B>clientCaps</B> 
behavior, introduced in Microsoft Internet Explorer 5, to obtain 
client capabilities information. The following is a sampling of the 
information that can be obtained:</P>
