[Nokia]

When using the library PDFDocument, is there a way to word wrap a sentence for paragraph in an invisible rectangle?

Drawing Multiline Text

This code creates a label with the text and returns a snapshot of the label: Sub TextToBitmap (Width As Int, Fnt As B4XFont, Clr As Int, Text As Object) As B4XBitmap Dim lbl As Label lbl.Initialize("") Dim x As B4XView = lbl x.Font = Fnt x.TextColor = Clr...

Upload a small project with this code.

Code with File.DirDefaultExternal = broken code.

I cannot test the PDF as it is no longer possible to access the data folder on newer versions of Android.
You should implement SaveAs: https://www.b4x.com/android/forum/t...list-of-other-related-methods.129897/#content

Have you tried to run this? Your code is broken.

SaveAs - Let the user select a target folder + list of other related methods

No, I could not run this as my tablet android version is 7.1.1

I found a way to fix my issue.. I wrote a crude function to allow text to wrap and allow the text to be selectable. In the bitmap version you can't select and copy text from pdf. If anybody has a cleaner way to write the function let me know.. thanks..

Private Sub PDF_WrapText(PDF As PdfDocument, Text As String, x As Float, y As Float, Length As Float, Font As Typeface,TextSize As Float, TextColor As Int, Alignment As String) As PdfDocument
    
    Dim y1 As Float = y
    Dim b As Int = 0
    For c = 1 To Text.Length
        If Text.SubString2(b, c).Length > Length / 4.5 Then
            PDF.Canvas.DrawText(Text.SubString2(b,Text.LastIndexOf2(" ", c)), x,y1,Font,TextSize,TextColor, Alignment)
            b = Text.LastIndexOf2(" ", c) + 1
            y1 = y1 + TextSize
        End If
        If c = Text.Length And Text.SubString2(b,c).Length > 0 Then
            PDF.Canvas.DrawText(Text.SubString2(b,c), x,y1,Font,TextSize,TextColor, Alignment)
        End If
    Next
    
    Return PDF
End Sub
