Deleting layers - PDF map

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Dear Planet PDF users, I am struggling with PDF map. I need to delete certain objects (text, lines, etc.). Well, I thought that this wouldn't be a problem so I've downloaded Acrobat pro trial and tried to filter objects I need to hide. The problem is that Acrobat doesn't show any layers and even deleting of all text objects is not possible for me. Also since the map is vector, I am experiencing freezes and so on. I only can delete text objects one by one but this usually ends with crashed Acrobat. Is there a possible solution or there is nothing to do with my problem? Thanks in advance. This is the pdf map: http://www.jirkov.cz/e_download.php?file=data/editor/115cs_11.pdf&original=85.pdf
(czech language)

This is how I need it to look like. (this is prtscr of pdf in loading when certain objects (exactly those I need to delete) weren't loaded yet but the resolution is too low for my needs)

	When I open your PDF with Acrobat DC Professional and open the "Layers" navigation panel I see no layers.

	Well, this is the problem. Maybe author didn't manage to make layers or doesn't want others to edit this pdf? I wouldn't mind and eventually delete objects manually but it takes a long time to delete even single text object and the Acrobat often crashes.

	As I see the very problem here is that PDF has no layers actually. It happens when a file is made through some poorly crafted editor or converted from a jpeg image. I order to fix that you shall run it with some tool like that https://edit-pdf.pdffiller.com/ at least in my cases it always recognizes layers well
