             Summary: Text corruption
                 Key: PDFBOX-2581
                 URL: https://issues.apache.org/jira/browse/PDFBOX-2581
             Project: PDFBox
          Issue Type: Bug
    Affects Versions: 1.8.8
            Reporter: pupkin


I use PDFBox 1.8.8 and try to add new text to existing pdf file. The problem is that text added by me is looking compressed for this specific pdf

 

[original pdf (i think this file is source of problem)|https://www.dropbox.com/s/foeb9raub20lbnx/1.pdf?dl=0]

(it is working for other pdfs).


[pdfbox generated file|https://www.dropbox.com/s/4e5ozksm5ycv7v2/2.pdf?dl=0]

It was not shown in all originally but i fixed problem with this command (set font display mode)

{code}
content.appendRawCommands("0 Tr ");  
{code}

I was working with pdf matrix and checked almost everything ... and do not see way how may i fix the problem...
{code}
content.setTextMatrix(1, 0, 0, 1, 0, 0);
{code}
questions:

1) why pdfbox not  ignore  page  font settings and use  default  options of font on page?

2) what mode was used in my pdf to archive such kind transformation how  i  may  fix   problem  to  show  font   correctly?


{code}
private static void writePdfBoxStamp(PDDocument document, int page,
        float topLeftX, float topLeftY, float width, float height,
        String text, float  itemFontSize, int[] color, int rotation) throws IOException {

    PDPage pdfPage = (PDPage) document.getDocumentCatalog().getAllPages().get(page);
    PDPageContentStream content = new PDPageContentStream(document, pdfPage, true, true);


    // COSDictionary pageFonts = pdfPage.getResources().getCOSDictionary();


    //border draw
    float lineWidth = 2;

    float bottomLeftX = topLeftX;
    float bottomLeftY = topLeftY - height;
    float topRightX = topLeftX + width;
    float topRightY = topLeftY;

    float radius = 10;

    content.setLineWidth(lineWidth);
    content.setStrokingColor(new Color(color[0], color[1], color[2]));


    content.setNonStrokingColor(new Color(color[0], color[1], color[2]));

    PDFont font = PDType1Font.HELVETICA_BOLD;
    int fontSize = (int) itemFontSize;


    float linesHeight = font.getFontDescriptor().getFontBoundingBox()
            .getHeight()
            / 1000 * fontSize;
    float txtLineWidth = font.getStringWidth(text)
            / 1000 * fontSize;

    content.setFont(font, fontSize);

    content.beginText();

    content.setFont(font, fontSize);

    float  posTextX = topLeftX + (width-txtLineWidth)/2;
    float  posTextY = topLeftY  - height/2 - linesHeight/2 + lineWidth;



    if (rotation > 0) {
        int  step = 0;
        // clockwise rotation
        if (rotation == 90) {
            step = 6;
            posTextX = topLeftX + (width + linesHeight)/2 - lineWidth;
            posTextY = topLeftY - (height + txtLineWidth)/2;
        }
        if (rotation == 270) {
            step = -6;
            posTextX = topLeftX + (width - linesHeight/2)/2;
            posTextY = topLeftY - (height - txtLineWidth)/2;
        }
        content.setTextRotation(-step*Math.PI*0.25, posTextX, posTextY);

    } else {
        content.moveTextPositionByAmount(posTextX,posTextY);

    }

    content.appendRawCommands("0 Tr "); //set normal text procession

    content.drawString(text);


    content.endText();

    content.stroke();


    content.close();
}
{code}
