Thank you for contacting support.

You may convert HTML document to an image of any dimensions with Aspose.HTML for Java 19.3 using below code snippet:

HTMLDocument document = new HTMLDocument(dataDir + "business card.html");
HtmlRenderer renderer = new HtmlRenderer();
ImageDevice device = new ImageDevice(dataDir + "Test_out.png");
    device.getOptions().getPageSetup().setAnyPage(new Page(new Size(500, 700), new Margin(0, 0, 0, 0)));
    renderer.render(device, document);

We hope this will be helpful. Please feel free to contact us if you need any further assistance.


if we want to convert this html-file html png with the given dimensions from the first html-tag, the output is too small.
output_real_table_dimensions .png (10.4 KB)
we have to multiply the given dimensions with 1.1 and resize the image again. The border isn’t rendered, the alignment of the text is wrong and kerning is also different.
output_table_dimensions x 1.1.png (9.7 KB)

we need an exact rendering of the given html…



Would you please share the code snippet you are using. We have used above code snippet exactly and generated image has been attached for your kind reference. karte_out.png


we tested the code provided by you. As you can see in the attached Image comparison.png (25.8 KB), there are a few problems:

  • Table and Div borders and box shadows are not rendered
  • Kerning of Arial (and others) is different
  • we set zero margin, but there is whitespace around the image grafik.png (14.6 KB)

Code used:
HTMLDocument htmlDocument = new HTMLDocument(dataDir + this.inputFile);
HtmlRenderer htmlRenderer = new HtmlRenderer();
ImageDevice imageDevice = new ImageDevice(dataDir + this.outputFile);
imageDevice.getOptions().setHorizontalResolution(new Resolution(300, UnitType.DPI));
imageDevice.getOptions().getPageSetup().setAnyPage(new Page(new Size(322, 208), new Margin(0, 0, 0, 0)));
new License().setLicense(“Aspose.Total.Java.lic”);
htmlRenderer.render(imageDevice, htmlDocument);
