Hi,
i've found this class awesome.
At the end of file there is a TODO: "Scale the text width to fit the OCR
bbox";
I developed this TODO:
You replaced TODO row with this:
boolean textScaled = false;
do {
float lineWidth = defaultFont.getBaseFont().getWidthPoint(line,bboxHeightPt
);
if(lineWidth < bboxWidthPt){
textScaled = true;
} else {
bboxHeightPt-=0.1f;
}
} while(textScaled==false);
After, i suggest to replace this row:
cb.setFontAndSize(defaultFont.getBaseFont(), Math.round(bboxHeightPt));
with this:
cb.setFontAndSize(defaultFont.getBaseFont(), bboxHeightPt);
Ciao! (I'am italian! :-p)
