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.
