Dear all,
in the meantime I could figure out what to change to achieve this (add
custom geostat legend to pdf output instead of original legend generated
for pdf output).
Just in case anyone wants to do a similar thing, here the most basic
steps I did:
1) In your project in ClientGeostat.php add function that builds custom
a legend image etc.(one for every user and request)
2) transfer the path if the generated image and its dimensions via
$_SESSION to CwFpdf.php
3) In CwFpdf.php in function addLegendItem replace $icon content with
path to your image
adapt width and height
$iWidth=$_SESSION['LegendWidth']/4;
$iHeight=$_SESSION['LegendHeight']/4;
adapt block size to fit legend images with dynamic sizes
$block->width=$_SESSION['LegendWidth']/4;
$block->height=$_SESSION['LegendHeight']/4;
comment out the lines
# $iWidth =
PrintTools::switchDistUnit($this->general->legendIconWidth, 'pt',
#
$this->general->distUnit);
# $iHeight =
PrintTools::switchDistUnit($this->general->legendIconHeight, 'pt',
#
$this->general->distUnit);
