InvalidDrawingAttributesWidth

Error message

InvalidDrawingAttributesWidth

What it means

ExtendedPropertySerializer rejects a value assigned to a DrawingAttributes extended property (Width/Height guid) whose double value is NaN, negative-below MinWidth, or above DrawingAttributes.MaxWidth. The library enforces the documented DrawingAttributes width range before persisting to ISF. It is an ArgumentOutOfRangeException naming the offending parameter.

Solutions

1. Validate the double before assigning: check !double.IsNaN && >= DrawingAttributes.MinWidth && <= DrawingAttributes.MaxWidth
2. Clamp the value: Math.Max(DrawingAttributes.MinWidth, Math.Min(DrawingAttributes.MaxWidth, value))
3. Replace NaN with a sane default such as DrawingAttributes.DefaultWidth
4. Guard upstream data sources (config, files, network) that feed widths

Example fix

// before
attr.AddPropertyData(CustomAttributeSerializer.CurrentWidthGuid, computedWidth); // may be NaN/negative
// after
if (!double.IsNaN(computedWidth) && computedWidth >= DrawingAttributes.MinWidth && computedWidth <= DrawingAttributes.MaxWidth)
    attr.AddPropertyData(CustomAttributeSerializer.CurrentWidthGuid, computedWidth);
else
    attr.Width = DrawingAttributes.DefaultWidth;

static bool IsValidWidth(double w) => !double.IsNaN(w) && !double.IsInfinity(w) && w >= System.Windows.Ink.DrawingAttributes.MinWidth && w <= System.Windows.Ink.DrawingAttributes.MaxWidth;

static bool IsFiniteInRange(double v, double min, double max) => double.IsFinite(v) && v >= min && v <= max;

try { attr.AddPropertyData(widthGuid, value); }
catch (ArgumentOutOfRangeException) { attr.Width = System.Windows.Ink.DrawingAttributes.DefaultWidth; }

When it happens

Trigger: Calling ExtendedPropertySerializer.SaveAsBaseValue or DrawingAttributes extended-property serialization with value = double.NaN, a negative width, or a value > DrawingAttributes.MaxWidth for the Width (or Height-family) guid.

Common situations: Computing a stroke width from user input or math that yields NaN (e.g. 0/0) or negative values; deserializing config or older files with unvalidated widths; unit tests probing boundary values.
