The Author mode and the output transformation process might render the images referenced in an XML document differently, since they use different rendering engines.

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

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 control the rendered image.
  • If you want to scale both the width and height of an image proportionally, use the scale attribute.
Note: As a Java application, Oxygen XML Editor uses the Java Advanced Imaging API that provides a pluggable support for new image types. If you have an ImageIO library that supports additional image formats, just copy this library to the [OXYGEN_INSTALL_DIR]/lib directory.
