pointObj draw - missing original coordinates

[brunovani22]

Hi, first, sorry if any mistakes, it is my first post. When using mapscript "draw" for a pointObj, the object loses its originals coordinates, assigning the image coordinates values.

by example-->

echo "before draw: ".$click_geo->x.", ".$click_geo->y."<br>";

$image = $map->draw(); #create map figure

$layer = $map->getLayerByName('virtual');

$click_geo->draw($map, $layer, $image, 0 ,'');

echo "after draw: ".$click_geo->x.", ".$click_geo->y."<br>";

output: before draw: 467738, 7543543 after draw: 346, 180

I try to use php clone for backup the value, but an error occurs:

The problem is that, internally, the point has to be transformed in pixel to be drawn. The behavior is the same using other bindings. The issue should also applied to drawShape, drawLine etc. I see 2 options:

• Do nothing... the user will have to copy the original coordinates himself. (Manually or using the clone feature when it will be available) I don't thinks it's available in other bindings neither. ie. we can do a deepcopy of the object in python.
• Make the mapscript internal functions do a copy of the original object before calling the draw functions. This has a cost.... copying a big shapeObj/lineObj might has a big impact on the performance.

What do you think?

About the clonable objects... I created a new ticket for this enhancement: #4032.
