Returns the number of PdfParamItem objects in this collection.

Returns or sets the value for an item specified by Name. If the specified name is not found, a new item is added to this PdfParam object.

Usage:

objParam["Alignment"] = 2;

objParam["x"] = objParam["x"] + 20;

Adds one or more parameters specified by ParamString to this PdfParam object. A parameter string contains a list of comma- or semicolon-separated Name=Value expressions. Spaces and case of characters are ignored. The order in which items are listed is immaterial.

The Value part of an expression may be an integer or fixed-point float value. Integers may be presented in decimal or hexadecimal formats. Hexadecimal numbers are prefixed with a &H or #. A Value may also be one of the pre-defined constants such as blue (and other colors), true, false, and other values specific to a particular method or property.

If a parameter with the same name already exists in the PdfParam object, it is overwritten with the new value specified in the parameter string.

Examples (all produce the same result):

Param.Add "x=10; y=20; alignment=right; color=blue"

Param.Add "Alignment=1;X=10,Y=20;color=&H0000FF"

Param.Add "color=#0000FF;Alignment=Right, X=10, Y=20"

Clears the collection of all parameter items.

Returns True if a parameter item specified by Name is present in the collection.

Removes a parameter item specified by Name from the collection.

Same as the Add method, but clears the collection before adding new items. Therefore, a call

objParam.Set( "parameter string" );

is equivalent to

objParam.Clear();
objParam.Add( "parameter string" );
