> Hi everyone!!!
> PDFBox doesn't write tiff images propertly.
> In tiff documentation there are many fields that are
> not suported by this library. 
> 1. DPI (XResolution, YResolution, ResoulutionUnit)
>    XResolution and YResolution IFDFields are hardcoded
> (300 dpi value for both), ResolutionUnit is not even
> taken into account. User is forced to write those
> values by hisself.
> 2. FillOrder
>    It is a logical order of bits within a byte (ref.
> TIFF6.pdf document page 32). In PDFBox this entry is
> allways 1 (because of lack it in library this field has
> default value 1 - available are 1 and 2). The efect of
> this is that the data is not properly recognized by pdf
> viewers - error shown:
> "No sufficient data for the image".
> Here is code for creating pdf page with tiff image:
