Image Rendering

The Author editor and the output transformation process might render differently the images referenced in the XML document, since they use different rendering engines. The following image formats are supported by default: GIF, JPEG, PNG, SVG, BMP. Oxygen XML also provides experimental support for CGM images.

To allow Oxygen XML to display other formats (like TIFF, JPEG 2000 or WBMP, for example) install the Java Advanced Imaging (JAI) Image I/O Tools plug-in.

When an image cannot be rendered, Oxygen XML Author XML Author displays a warning message that contains the reason why this is happening. Possible causes:

Scaling Images

Image dimension and scaling attributes are taken into account when an image is rendered. The following rules apply:
  • if you specify only the width attribute of an image, the height of the image is proportionally applied;
  • if you specify only the height attribute of an image, the width of the image is proportionally applied;
  • if you specify width and height attributes of an image, both of them controls the rendered image;
  • if you want to scale proportionally both the width and height of an image, use the scale attribute.
