Hello
We generate a URL to send to an image web service. The URL works fine in a browser but displays as a black rectangle using -
imageEnView1.io.loadFromUrl(TIdURI.URLEncode(strChartURL));
strChartURL is a side string of approx. 2500 characters. The issue only started when we increased the length of the URL.
imageEnView1.io.loadFromUrl(strChartURL); returns nothing.
The URL is -
