CAM::PDF::Renderer::Text - Render an ASCII image of a PDF page
use CAM::PDF; my $pdf = CAM::PDF->new($filename); my $contentTree = $pdf->getPageContentTree(4); $contentTree->render("CAM::PDF::Renderer::Text");
This class is used to print to STDOUT the coordinates of each node of a page layout. It is written both for debugging and as a minimal example of a renderer.
The $CAM::PDF::Renderer::Text::xdensity and $CAM::PDF::Renderer::Text::ydensity define the scale of the ASCII graphical output device. They both default to 6.0.
Calls the superclass constructor, and initializes the ASCII PDF page.
Prints the characters of the screen to our virtual ASCII framebuffer.
Serializes the framebuffer into a single string that can be easily printed.
