ASP.NET - Distortion when outputting text and drawing lines

1. offizieller Beitrag

    Hi,

    We are having problems with wPDF 2.3.1441.28155 & wPDFControl02 2.9.4.3 in ASP.NET 1.1. I have included a simple example below that exhibits the error.

    We are trying to print a report with grid lines around the text giving the look of a table. We can, separately, print the text correctly and print the grid lines correctly. However, when we try to print the two together the page becomes distorted. The height of the output text increases and the width decreases, as if the resolution is changing.

    If the line to draw has no dimensions the error does not occur: lPrinter.Canvas.Drawline(lPen, 1, 1, 1, 1). The problem occurs using TextOut or DrawString.

    Help would be appreciated.
