I have a PDF that contains one page, with a vector image on it.
I want to use the left half of the image on the backside of the front cover-page of my work, and the right half on the front of the back cover-page (since the back of the back cover-page will be on the "outside" of my work). In other words: If my work were just the front and back cover-pages (nothing in between), you'd see the entire image on the inside of both covers.
pdfinfo from xpdf (as per this answer) to get the dimensions of the original image pdf (163 * 77 pts). Using
pdfcrop (as per this question) I managed to create both halves, with dimensions 81.5 * 77 pts.
However, inspecting the cropped images with Inkscape, I see that the cropped-out part of the image is still contained in the pdf.
Is there a way to crop out-of-view vertices of a vector graphic? Right now, when they both exist in the same document, the entire image will be included in the final document twice, which makes the file big, and my computer slow when viewing it.
