[iText-questions] Issue regarding Unbalanced save/restore state operators.

[Harsha Kaundinya]

Hi All,

I am using itextpdf-5.4.0.jar

I am getting the below exception on document.close();

com.itextpdf.text.exceptions.IllegalPdfSyntaxException: Unbalanced
save/restore state operators.

I have read the itext documentation about regarding unbalanced save state
and restore state and have *not *violated the below points

- Unbalanced beginText() and endText() combinations
- iText state operators outside a beginText() and endText() sequence
- iText for which you forgot to set a font and size

A small code snippet from my code is given below

public void addSampleText() {
if (!this.printPreview) {
try {
BaseFont bf = BaseFont.createFont(BaseFont.TIMES_ROMAN,
BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
template.saveState();
template.setRGBColorFill(this.stk_Red, this.stk_Green,
this.stk_Blue);
PdfGState gstate = new PdfGState();
gstate.setFillOpacity(0.7f);
template.setGState(gstate);
template.beginText();
template.setFontAndSize(bf, sampleFontSize);
template.showTextAligned(PdfContentByte.ALIGN_CENTER,
"Sample Label", sampleX, sampleY,

(float)(Math.toDegrees(Math.atan2(this.stk_height, this.stk_width))));
template.endText();
template.restoreState();
} catch (Exception exce) {
exce.printStackTrace();
}
}
}

The template object is of type *PdfTemplate.*

I read through blogs and few have stated that this exception occurs iText 5
onwards.

Can any one suggest me why this exception has occurred?

Unfortunately, you didn't take the time to create a small standalone
sample that reproduces the exception.
I had to do this in your place (something I usually only do for paying
customers), and I wasn't able to reproduce the problem using almost the
exact same code snippet you provided. If you run SanityCheck.java, you get
a PDF file named sanity.pdf without any exceptions being thrown.

In other words: you're not giving us sufficient info to allow us to help
you, which means you won't get any help.
