Scaled MultiText and horizontal alignement

[Mario Bianchi]

Hi,
Found a problem with Graphics.DrawMultiText when both horizontal scaling and horizontal aligmement is used, right and centered text are not draw at corect x position.
Here the code to reproduce the problem:

PDFDocument pdfDoc = new PDFDocument();
IPDFFont pdfFont;

pdfFont = pdfDoc.Fonts.Add (Environment.GetEnvironmentVariable ("systemroot") + @"\Fonts\ARIAL.TTF");
pdfFont.Size = 12.0F;

IPDFPage firstPage = pdfDoc.Pages[0];

IPDFGraphicState DrawProp = pdfDoc.CreateGraphicState ();
RectangleF DimPos = new RectangleF (200, 30, 200, 30);

DrawProp.Scale (0.5F, 0.5F);

DrawProp.TextAlignment = TextAlignment.Right;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!", pdfFont, DrawProp);

DimPos.Offset (0, 35);
DrawProp.TextAlignment = TextAlignment.Center;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!", pdfFont, DrawProp);

DimPos.Offset (0, 35);
DrawProp.TextAlignment = TextAlignment.Left;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!", pdfFont, DrawProp);

DimPos.Height = 60;
DimPos.Offset (0, 35);

DrawProp.TextAlignment = TextAlignment.Right;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!Test123Test Multi Lines", pdfFont, DrawProp);

DimPos.Offset (0, 65);
DrawProp.TextAlignment = TextAlignment.Center;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!Test123Test Multi Lines", pdfFont, DrawProp);

DimPos.Offset (0, 65);
DrawProp.TextAlignment = TextAlignment.Left;
firstPage.Graphics.DrawRectangle (DimPos, DrawProp);
firstPage.Graphics.DrawMultiText (DimPos, "Hello World!Test123Test Multi Lines", pdfFont, DrawProp);

pdfDoc.Save("Sample.pdf");

Without Scale, the code work fine.

Hi Mario,

Thanks again for the code! I was able to reproduce the issue. However, if we scale to the correct position, we can have the proper alignement.

Can you please replace the Scale property with the following values?

DrawProp.Scale (1f,1f);

This will make your sample work. However, I agree that while scaling the coordinates, the text should have proper alignment. I have forwarded this issue to development team.

Dhivya.
