public static double pointToPixel(double points) |
-
Converts points to pixels at 96 dpi.
1 inch equals 72 points.
- Parameters:
points - The value to convert.
Example: Opens an HTML document with images from a stream with a base URI.
// We are opening this HTML file:
/*
<html>
<body>
<p>Simple file.</p>
<p><img src="Aspose.Words.gif" width="80" height="60"></p>
</body>
</html>
*/
String fileName = getMyDir() + "Document.OpenFromStreamWithBaseUri.html";
// Open the stream.
InputStream stream = new FileInputStream(fileName);
// Open the document. Note the Document constructor detects HTML format automatically.
// Pass the URI of the base folder so any images with relative URIs in the file can be found.
Document doc = new Document(stream, getMyDir());
// You can close the stream now, it is no longer needed because the document is in memory.
stream.close();
// Lets make sure the image was imported successfully into a Shape node.
// Get the 1st shape node in the document.
Shape shape = (Shape)doc.getChild(NodeType.SHAPE, 0, true);
// Verify some properties of the image.
Assert.assertTrue(shape.isImage());
Assert.assertNotNull(shape.getImageData().getImageBytes());
Assert.assertEquals(80.0, ConvertUtil.pointToPixel(shape.getWidth()));
Assert.assertEquals(60.0, ConvertUtil.pointToPixel(shape.getHeight()));
// Save in the DOC format.
doc.save(getMyDir() + "Document.OpenFromStreamWithBaseUri Out.doc");
