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

	The program that you use to create the PDF must make the layers. If it cannot, then you have to make the layers in separate files and then you can use the Navigation page to import the PDF file as a layer to make each file into a layer. You will then need to set each layers property. About PDF layers
