[jira] [Commented] (PDFBOX-4826) PDF rendering produces distorted
images at various DPI
[ https://issues.apache.org/jira/browse/PDFBOX-4826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17103228#comment-17103228 ]
Tilman Hausherr commented on PDFBOX-4826:
-----------------------------------------
What code are you using to render? Directly to an image or rendering to a graphics device? Do you have the same effect when working from the command line and using PDFToImage? Because that is what I did and all is OK, see attached file.

> I am getting different output for a pdf document when converting into image.
> At 300 DPI the checkboxes are rendered at random places and have different shapes.
> At 301 or 209 DPI they are being rendered properly. For different DPI it is having this behavior like at 150 DPI it is again distorted and 149 it looks fine.
>
> I have attached the pdf. The page number 2 of the pdf document has issues.
