Images

Property

Description

Image height
Image width

The displayed image size in pixels.  When specified, images are not displayed at their normal size but are scaled according to the sizes specified by ImageWidth and ImageHeight.  Both ImageWidth and ImageHeight must be provided in order to specify the image size in pixels.  ImageWidth and ImageHeight are used in conjunction with the “Pop ups” property.

ImageWidth and ImageHeight may be used when “Image percent size” is not specified.  Any positive integer value may be specified.  No default value is assumed for these properties.

“Image percent size” has higher priority over ImageWidth and ImageHeight.  If all three are specified then the image will be displayed according to the “Image percent size” value.  If the “Image percent size” property is missing, ImageWidth and ImageHeight values are used.

Image percent size

The size of the thumbnail image displayed.  When specified, images are not displayed at their normal size but are scaled according to the percentage specified by “Image percent size”.  “Image percent size” is used in conjunction with the “Pop ups” property.

“Image percent size” specifies a percentage of the image’s actual size.  Any positive number starting from 0.0 may be specified.  Values less than 1.0 are taken as an actual percentage.  For example, a value of 0.3 is interpreted as 30% and the image will be displayed with 30% of its original size.

The default value for “Image percent size” is the “default” string which represents a default value, typically 20%.

Default

Display the image at its default size, typically 20% of its full size.

Maximum image height
Maximum image width

Images are displayed unaltered up to ImageMaxWidth and ImageMaxHeight  (pixels).  Images exceeding this size are proportionately reduced by setting the HTML “width” and “height” parameter to ImageMaxWidth and ImageMaxHeight.
