Thanks by the response. Yes, you're right, but I need a process more or less 
complicated. I need a simply and if is possible, automatic way to do that for a 
good performance.

Hi. Sorry for my bad english.



I have a problem with the shp2pgsql.exe tool (download since Carto.net) and my 
PHP-MySQL application. I don't know why my SVG is resulting how if it was 
reflected by a horizontal mirror. The PHP code (after de SQL spatial query) is 
like this:



//geometry in Well-Know-Text format

$wkt="MULTIPOLYGON(((0 0,0 3,3 3,3 0,0 0),(1 1,1 2,2 2,2 1,1,1)),((6 7,8 9,4 
5,6 7)))";



$d= str_replace("MULTIPOLYGON(((", "M ", $wkt);

$d = str_replace(")),((", " z \n M ", $d);

$d = str_replace("),(", " z \n M ", $d);

$d = str_replace(",", " L ", $d);

$d = str_replace(")))", " z \n", $d);

/*

result:

M 0 0 L 0 3 L 3 3 L 3 0 L 0 0 z \n M 1 1 L 1 2 L 2 2 L 2 1 L 1 1 z \n M 6 7 L 8 
9 L 4 5 L 6 7 z \n

*/



There is a simple manner for turn the image since SVG, how change the 
coordinate system or something like? I know there is simple making a PHP 
function that do that, but my SVG's are little big and could consume too many 
resources and processing time.



First of all, I need to preserve the performance and the easy-to-use issue. 
Someone have any idea?



Thanks,

Ed

I have a problem with the shp2pgsql.exe tool (download since Carto.net) and my 
PHP-MySQL application. I don’t know why my SVG is resulting how if it was

like this:
