Is it possible in PDFlib to create an svg graphic from another image-file (like png) and than put it out in the pdf? Like first load the png image with $p->load_graphics and than create a svg file within pdflib? I googled this but found nothing that fits my requirement.

For explanation: I have a png graphic and want to create a svg file within my pdflib program, so I can give this image a shadow. Or is it possible to put a shadow on the image through another way?

Unfortunately, PDFlib does not have built-in functionality to convert an image file (such as PNG) to an SVG graphic. You would need to use a separate tool or library to convert the image file to SVG before using PDFlib to include it in a PDF document.

One possible approach would be to use a tool like ImageMagick to convert the image file to SVG, and then use PDFlib to include the SVG graphic in the PDF document. Here is an example of how you could do this:

php
// Load the PNG image file
$image = $p->load_image("input.png", "auto", "");

// Convert the PNG image to SVG using ImageMagick
exec("convert input.png output.svg");

// Include the SVG graphic in the PDF document
$p->fit_image($image, 100, 100, "scale=0.5");

// Close the image
$p->close_image($image);


In this example, we first load the PNG image file using `$p->load_image()`. We then use the `exec()` function to run the `convert` command from ImageMagick to convert the PNG image to SVG. Finally, we use `$p->fit_image()` to include the SVG graphic in the PDF document.

Please note that this is just a basic example and may need to be adapted to fit your specific requirements and environment.
