## Renderer.OutputFormatDef

### Description

Returns a two-dimensional Array which lists the format definition of the output image format in question. Each definition item is a triplet of siRenderChannelType, siImageDataType and siImageBitDepth values.
The format definition can be queried by giving either the format name or the format's file extension.

### C# Syntax

    Object Renderer.OutputFormatDef( String in_strName );

### Scripting Syntax

    Renderer.OutputFormatDef();

### Examples

#### JScript Example

    // Show the output format definition of the EXR format as
    // used by mental ray.
    var oMentalRay = Application.Renderers.Item( "mental ray" );
    var aFormatDef = (new VBArray( oMentalRay.OutputFormatDef( "exr" ) )).toArray();
    var aChannelType = new Array( "Unknown", "Color", "Grayscale", "Depth", "Normal", "Vector", "Label" );
    LogMessage( "OpenEXR framebuffer support:" );
    for( var i = 0; i < aFormatDef.length; i += 3 )
    {
            LogMessage( "Channel Type: " + aChannelType[ aFormatDef[ i ] ] +
                        " - Data Type: " + aFormatDef[ i + 1 ] +
                        " - Bit depth: " +
                          ( ( aFormatDef[ i + 2 ] & 16 ) ? "Float " : "Integer " ) +
                          ( 1 << ( aFormatDef[ i + 2 ] & 15 ) ).toString() );
    }
