Why a got this matrix in one of pdf? q 0 319 -118 0 4866 1373.73 cm /R20 Do Q q 0 319 -118 0 4866 1373.73 cm /R21 Do Q q 0 319 -118 0 4866 1373.73 cm /R20 Do Q Numbers like 4866 and 1373 takes me coordinates bigger than page dimension. Maybe its not only this matrix multiplying when i compute coordinates for image? пн, 18 февр. 2019 г. в 11:03, Tilman Hausherr <[email protected] <mailto:[email protected]> >: > You can use the PDFStreamParser class, see the RemoveAllText.java example. > > 0 319 -118 0 4866 1373.73 cm > > is a transform ("Concatenate matrix to current transformation matrix"). > That is explained in the PDF specification in "8.3.2 Coordinate Spaces". > Yes, it influences the size and the position (and more, here: rotation) > of the image. > > Tilman > > > Am 18.02.2019 um 06:57 schrieb Евгений Король: > > Hello.
