I am creating a text pattern within a rectangle with the following snippet:
var canvas = m_writer.DirectContent; float fillTextSize = 6.0f; string filltext = "this is the fill text!"; float filltextWidth = m_dejavuMonoBold.GetWidthPoint(filltext, fillTextSize); PdfPatternPainter pattern = canvas.CreatePattern(px, py, filltextWidth, fillTextSize); pattern.BeginText(); pattern.SetTextMatrix(0, 0); pattern.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_FILL); pattern.SetRGBColorStroke(190, 190, 190); pattern.SetRGBColorFill(190, 190, 190); pattern.SetFontAndSize(m_dejavuMonoBold, 6.0f); pattern.ShowText(filltext); pattern.EndText(); canvas.Rectangle(px, py, pw, ph); canvas.SetPatternFill(pattern); canvas.Fill();
xStep parameter of the pattern?
I am looking for a pattern like this:
|this is the fill text! this is the fill text! this| |his is the fill text! this is the fill text! this | |is is the fill text! this is the fill text! this i| |s is the fill text! this is the fill text! this is| | is the fill text! this is the fill text! this is |
If I understand your question correctly, you need something like this: text_pattern.pdf
Text pattern example
We are using tiled patterns and the problem you experience is that all tiles are regular. If you want an irregular pattern, you need to use a workaround. Such a workaround is shown in the TextPattern example.
In iText 7 there is a Tiling class with a constructor for creating a tile. Declaring pattern you can set the width, height, X and Y offsets (like PdfPatternPainter in iText 5). Then you should create a PdfPatternCanvas using your tile:
PdfPattern.Tiling tilingPattern = new PdfPattern.Tiling(filltextWidth, 60, filltextWidth, 60);
PdfPatternCanvas patternCanvas = new PdfPatternCanvas(tilingPattern, pdf);
patternCanvas.beginText().setFontAndSize(font, 6.f);
// Start with an X offset of 0
float x = 0;
// Add 6 rows of text
// The font is 6, so use a leading of 10:
for (float y = 0; y
As far as I know, adding the text more than once to the pattern, is the only way to achieve the type of pattern you require.
