Re: Write to and read from scalar

Ahh, that's what I was after. Many thanks ;) However, I can't seem to get PDF::API2's image methods to accept the scalar data as input: $png = $pdf->image_png($file); I know my scalar contains a valid PNG image as I've written the source image to a scalar, closed the file handle, opened another and written the scalar back to disc and the file is a valid PNG. Any ideas on how to do this please? Thanks again.

`$png = $pdf->image_png($file);` As it looks, the underlying package PDF::API2::Resource::XObject::Image::PNG doesn't expect a (pre-opened) file handle, but a name of a file, which it goes to open itself. In case the functionality is important to you, you might want to try modifying the code yourself such that the `open` is done only in case `$file` isn't already a valid file handle (check with ref).
