Roman resolved PDFBOX-3617.
---------------------------
Resolution: Invalid
> Incorrect font width on verical text
> ------------------------------------
>
> Key: PDFBOX-3617
> URL: https://issues.apache.org/jira/browse/PDFBOX-3617
> Project: PDFBox
> Issue Type: Bug
> Affects Versions: 1.8.12, 2.0.3
> Reporter: Roman
> Attachments: 6L.pdf
>
>
> On the attached document we are extracting glyph coordinates as shown in code
> snippet below. The "w" variable is used to calculate the width of glyph. It
> is returning wrong value.
> The document contains "........KKKKWWWW!!!!0000" string. For dots it returns
> too big value, but for "K" characters it returns to small value.
> {code}
> public class Extractor extends PDFTextStripper {
> //<...CUT...>
> protected void writePage() throws IOException {
> for (List<TextPosition> textList : charactersByArticle) {
> //charactersByArticle was inherited from base class
> Iterator textIter = textList.iterator();
> //<...CUT...>
> while (textIter.hasNext()) {
> TextPosition position = (TextPosition)
> textIter.next();
> //<...CUT...>
> PDFont font = position.getFont();
> //<...CUT...>
> float w;
> try {
> if (font instanceof PDType0Font && ((PDType0Font)
> font).getDescendantFont() == null) {
> //in 1.8.12 code flows here
> Method method =
> font.getClass().getDeclaredMethod("getDescendantFonts");
> method.setAccessible(true);
> COSArray arr = (COSArray) method.invoke(font);
> w = PDFontFactory.createFont((COSDictionary) ((COSObject)
> arr.get(0)).getObject()).getFontWidth(c);
> } else {
> //in 2.0.3 code flows here, but still, with the same result. Incorrect values
> are returned.
> w = font.getFontWidth(c);
> }
> {code}
