Discussion

Coupled with PV‑WAVE imaging, rendering, and visualization capabilities, the HTML_IMAGE function allows you the flexibility of visualizing your data in an HTML document over the Internet.

For an example of how to create a GIF file from PV‑WAVE for inclusion in an HTML document, see the following demonstration:

(UNIX) <wavedir>/demo/web/html/html_demo.pro

(WIN) <wavedir>\demo\web\html\html_demo.pro

where <wavedir> is the main PV‑WAVE directory.

Note:

Although HTML_IMAGE has many keywords enabling you to position the image within the containing element or browser window, you can also use the HTML_HIGHLIGHT function to specify any HTML image alignment attribute that is not included as a keyword for HTML_IMAGE. For example, the following line of code can be used to center an image:

HTML_HIGHLIGHT(HTML_IMAGE(url), 'CENTER')

Example

This example centers the PV‑WAVE logo in a browser window.

HTML_OPEN
HTML_BLOCK, HTML_HIGHLIGHT(HTML_IMAGE( $
!Data_dir + '/rw_logo.jpg'), 'CENTER')
HTML_CLOSE
