how can solve

what you're seeing actual content of image that's generated. need specify content/type, otherwise assumed text/plain or text/html. image seem png, so

header("content-type: image/png")

should sufficient. can see line commented out - needs included. 1 note though: needs go before actual image data output, need move top of script (or @ least above imagephp call).

edit: if want save resulting image file rather output browser, need pass second parameter imagepng function:

imagepng($iout, $myfilename)

see imagephp documentation more details

edit 2: if need content of created image use elsewhere, can use trick:

ob_start(); imagephp($iout); $image_data = ob_get_clean();

now got resulting image data in variable , can continue script.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
