[Java] "font-family" property does not support integer values

Aspose.Slides Product Family
1

I am using the saveToSvg method of the Slide and then I am writing those SVG files out to a PDF using iText + batik. Although the PDF generation is successful I am getting the following stacktrace:

The attribute “font-family” represents an invalid CSS value (“1”).
Original message:

I looked at the SVG file and there are nodes that have the following attribute:

font-family="1"

So I am wondering if

a) the saveToSvg method is writing invalid SVG markup
b) This has nothing to do with Aspose and I need to track it down on the batik level

Here is the code I am using to generate the PDF

PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(“image.test.pdf”));
document.open();
int width = 800;
int height = 600;
PdfContentByte cb = writer.getDirectContent();
PdfTemplate template = cb.createTemplate(width,height);
Graphics2D g2 = template.createGraphics(width,height);

PrintTranscoder prm = new PrintTranscoder();
TranscoderInput ti = new TranscoderInput(“520.svg”);
prm.transcode(ti, null);

PageFormat pg = new PageFormat();
Paper pp= new Paper();
// bunch of paper options here

ImgTemplate img = new ImgTemplate(template);
document.add(img);
document.close();

Thanks for the tipcs

font-family property should have font name like “Arial”, “Times New Roman” etc.
Thank you for the report, we will check why it happens in Java version.
