IDLgrBuffer objects have the following properties in addition to properties inherited from any superclasses. Properties with the word "Yes" in the "Get" column of the property table can be retrieved via IDLgrBuffer::GetProperty. Properties with the word "Yes" in the "Init" column of the property table can be set via IDLgrBuffer::Init. Properties with the word "Yes" in the "Set" column in the property table can be set via IDLgrBuffer::SetProperty.

An anonymous structure containing the values of all of the retrievable properties associated with this object (except IMAGE_DATA and ZBUFFER_DATA).
A Boolean value that determines the color model to be used for the buffer:
In a property sheet, this property appears as an enumerated list with the following options:
A two-element integer vector of the form [width, height] that specifies the dimensions of the buffer in units specified by the UNITS property. The default is [640,480].
An object reference of type IDLgrScene, IDLgrViewgroup, or IDLgrView that specifies the graphics tree of this object. If this property is set to a valid object reference, calling the Draw method on the destination object with no arguments will cause the object reference associated with this property to be drawn. If this object is valid and the destination object is destroyed, this object reference will be destroyed as well. By default the GRAPHICS_TREE property is set equal to the null-object.
A byte array representing the image that is currently rendered within the buffer. If the buffer uses an RGB color model, the returned array will have dimensions (3, xdim, ydim). If the window object uses an indexed color model, the returned array will have dimensions (xdim, ydim).
An integer that determines the number of colors (between 2 and 256) to be used if COLOR_MODEL is set to Color Index.
An object reference to a palette object (an instance of the IDLgrPalette object class) that specifies the red, green, and blue values to be loaded into the buffer's color lookup table.
This property is registered as a user-defined property, but it is hidden by default.
An integer that indicates the rendering quality at which graphics are to be drawn to the buffer. Valid values are:
In a property sheet, this property appears as an enumerated list with the following options:
A Boolean value that determines whether to register properties available for this object. Set this property to automatically register the following properties of the object for display in a property sheet. This property is useful mainly when creating iTools. By default, no properties are registered.
A two-element floating-point vector of the form [xres, yres] that specifies the device resolution in centimeters per pixel. This value is stored in double precision. The default value is: [0.035277778, 0.035277778] (72 DPI).
This property is registered as a user-defined property, but it is hidden by default.
A two-element integer vector of the form [width, height] that specifies the maximum allowed dimensions (measured in device units) for the buffer object.
| Note |
An integer value that indicates the units of measure for the DIMENSIONS property. Valid values are:
A floating-point array representing the zbuffer that is currently within the buffer. The returned array will have dimensions (xdim, ydim).
