Bold text with DrawTextBox

[puiguija]

Hi,

I need to write text with DrawTextBox method but part of this text must be in bold. Bold text is variable in length because comes from user input, i.e:

This is a sample text with bold words.

Any help would be appreciated.

Thanks,

Hi,

You can easily do that, all you have to do is set the resource font you want as bold, for example, create a font using https://www.gdpicture.com/guides/gdpicture/GdP ... FontU.html
and mark the Bold parameter as true.

Then use that font in DrawTextBox.

Hope this helps.
Best,
Sami

Hi,

Thanks for the quick answer, but your proposal writes all text in Bold whereas I need to write just some words in bold.

Other option would be to combine several calls to DrawTextBox with different fonts but then I would need to know the x,y coordinates where to place the next word.

Hi Puiguija

You can use the function GetTextWidth() to know the width taken by a text in a specified font.

See this simple sample in VbNet to how you can use it

Code: Select all

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Pdf.NewPDF()
    Pdf.NewPage(PdfPageSizes.PdfPageSizeA4)
    Dim fntRegular As String = Pdf.AddStandardFont(PdfStandardFont.PdfStandardFontHelvetica)
    Dim fntBold As String = Pdf.AddStandardFont(PdfStandardFont.PdfStandardFontHelveticaBold)
    Pdf.SetOrigin(PdfOrigin.PdfOriginTopLeft)
    Pdf.SetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitMillimeter)
    Dim PosX As Double
    Dim PosY As Double
    PosX = 10
    PosY = 10
    PosX = DrawText(fntRegular, PosX, PosY, 10, "This text is regular.")
    PosX = DrawText(fntBold, PosX, PosY, 10, "This text is bold.")
    PosX = DrawText(fntRegular, PosX, PosY, 10, "This text is regular.")
    Pdf.SaveToFile("d:\test.pdf")
End Sub

Private Function DrawText(ByVal FntId As String, ByVal PosX As Double, ByVal PosY As Double, ByVal FntSize As Double, ByVal Text As String)
    Pdf.SetTextSize(FntSize)
    Pdf.DrawText(FntId, PosX, PosY, Text)
    Return PosX + Pdf.GetTextWidth(FntId, FntSize, Text)
End Function

Hope this help
