PDFlib - add SVG from string

Question

Is it possible to add SVG graphics to PDF page from string when working with PDFlib?

Documentation states that load_graphics() takes file name on disc. Is there a way around it?

Answer 1

sure, you can use PVF (PDFlib Virtual Filesystem) for this task. See PDFlib 9.2 Tutorial, chapter 3.1.3 "The PDFlib Virtual File System (PVF)" for a detailed introduction.

A sample for using this with a raster image is included in the PDFlib packages (starter_pvf.php) and also included in the PDFlib cookbook: starter_pvf.

    # We just read some image data from a file; to really benefit
    # from using PVF read the data from a Web site or a database instead

    $imagedata = read_file("../input/PDFlib-logo.tif");

    $p->create_pvf("/pvf/image", $imagedata, "");

    # Load the image from the PVF
    $image = $p->load_image("auto", "/pvf/image", "");
