Hello,
I am attempting to add a check box to my PDF using iTextSharp and the following
code:
PdfFormField field = PdfFormField.CreateCheckBox(m_PDFWriter);
Rectangle box = new Rectangle(m_CurrentX,
m_CurrentY,
m_CurrentX + Width,
m_CurrentY + Width);
field.SetWidget(box, PdfAnnotation.HIGHLIGHT_INVERT);
field.Flags = PdfAnnotation.FLAGS_PRINT;
field.FieldName = FieldName;
field.ValueAsName = Value ? "On" : "Off";
field.AppearanceState = Value ? "On" : "Off";
field.MKBorderColor = m_ForeColor;
field.MKBackgroundColor = m_FillColor;
PdfAppearance onApp = PdfAppearance.CreateAppearance(m_PDFWriter, Width, Width);
onApp.SetFontAndSize(m_Font.BaseFont, m_FontSize);
onApp.SetColorFill(m_FillColor);
onApp.SetColorStroke(m_ForeColor);
onApp.Rectangle(0, 0, Width, Width);
onApp.FillStroke();
PdfAppearance offApp = PdfAppearance.CreateAppearance(m_PDFWriter, Width,
Width);
offApp.SetFontAndSize(m_Font.BaseFont, m_FontSize);
offApp.SetColorFill(m_FillColor);
offApp.SetColorStroke(m_ForeColor);
offApp.Rectangle(0, 0, Width - 1, Width - 1);
offApp.FillStroke();
PdfAppearance defaultApp = PdfAppearance.CreateAppearance(m_PDFWriter, Width,
Width);
defaultApp.SetFontAndSize(m_Font.BaseFont, m_FontSize);
defaultApp.SetColorFill(m_FillColor);
defaultApp.SetColorStroke(m_ForeColor);
field.SetAppearance(PdfAnnotation.APPEARANCE_NORMAL, "On", onApp);
field.SetAppearance(PdfAnnotation.APPEARANCE_NORMAL, "Off", offApp);
field.DefaultAppearanceString = defaultApp;
m_PDFWriter.AddAnnotation(field);
The checkbox appears correctly whether or not it is on or off with the check
mark displayed correctly. When the checkbox is selected with the mouse the box
becomes completely filled with the fill color and the mark is not visible,
whether the next state is "On" or "Off". I almost looks like there is a pattern
that needs to be set for the rectangle that will display the checkmark when it
is filled.
Any pointers would be greatly appreciated. Thanks.
Bruce
