Tilman Hausherr commented on PDFBOX-193:
----------------------------------------
The CCITTFaxDecode filter is explained in 3.3.5 of the pdf spec. I don't see
any dpi there.
Btw, just for the record, the code you write about is
{code}
addTag(282, 300, 1); // X Resolution 300 (default unit Inches) This is arbitary
addTag(283, 300, 1); // Y Resolution 300 (default unit Inches) This is arbitary
{code}
in PDCcitt or in TiffInputStream, depending of the version.
> Getting tiff - PDCcitt.TiffWrapper object

> PDCcitt has hardcoded dpi information and it is 300 for
> x and y resolution (see PDCcitt line 519 and 520).
> Propose solution: set information about dpi in
> COSDictionary object (decodeParms variable)
