Images from a 4D Write Pro header may be accessed by using the commands WP Get header and WP Get elements. For example:

$header_o:=WP Get header(WPDoc; wk first page) $images_c:=WP Get elements($header_o; wk type image)

This can be useful, for instance, when the size of logos in a Write Pro document must be changed dynamically.

However, if the image is a picture variable, the variable must be computed beforehand using WP COMPUTE FORMULAS, like this:

WP COMPUTE FORMULAS(WPDoc) $header_o:=WP Get header(WPDoc; wk first page) $images_c:=WP Get elements($header_o; wk type image)
