I am trying to scale down a phrase until it will fit in a given rectangle. I'm
using a ColumnText, and calling go(true), then testing for HasMoreText. But
the status returned by go() keeps being 2 even when all the text fits easily
into the rectangle.
What am I doing wrong?
float fontSize = pageMetrics.getFontSizeMax();
Phrase labelPhrase = GeneratePhrase(fontSize);
// Now we scale the text down until either it fits or we run up against
the specified minimum font size
Rectangle textBox = getSpaceForLabelText();
ColumnText col = new ColumnText(directContent);
col.setSimpleColumn(textBox);
col.addElement(labelPhrase);
int textPrintingStatus = ColumnText.START_COLUMN;
try {
textPrintingStatus = col.go(true);
while(ColumnText.hasMoreText(textPrintingStatus) && fontSize >
pageMetrics.getFontSizeMin() ) {
fontSize--;
labelPhrase = GeneratePhrase(fontSize);
col.clearChunks();
col.addElement(labelPhrase);
textPrintingStatus = col.go(true);
}
result.printedFontSize = fontSize; // record the font size
actually used
} finally {
}
