change thumbnail view for a text and pdf files
Hi
I want to know how the thumbnail is created for pdf and text files in linux.Because I want to change the view of a thumbnail.
As we all know in Ubuntu text files icon(thumbnail)is created dynamiclly depends on file content.
It shows files first four lines as a icon.As File content changes for first four lines the icon also changes.
Also same is for PDF file.It shows first page as a icon(thumbnail).
If anyone know how this works,Please help me.
Thanks in advance.
