First, I am not a programmer, now the background to my question. I have a photo in JPG format that I have been asked to convert to a series of holes. I then have to burn the hole pattern (at a distance you can see the face in the pattern) in a mild steel plate. I need a program to convert the JPG to a vector file where the diameters of the holed are proportional to the darkness of the photo. I have found an open source program, StippleGen_2, that does this and on downloading it found that it is designed to run on Linux, MacOSX, and Windows.
I only have Windows. When I tried to run the exe file I was told that I needed Java. I downloaded JRE and installed it. I hope that this introduction explains the non technical phrasing of my question.
When I try to run StippleGen_2.exe in Windows 7 I get the message
“C:\ProgramData\Oracle\Java\javapath\javaw.exe
Unspecified Error”
On pressing OK I get a dialog box titled "Processing error" with the message
“Error calling ShellExecuteEx()”
On a friend’s MacBook the program ran successfully. The developers of StippleGen say that it runs OK on their Windows 7
I have reinstalled Java, changed browser from Internet Explorer to Google Chrome, done the same on a second PC and I still get the same messages.
Java JRE is on C:\ and StippleGen is on D:\ - Could this be the problem?
What should I try next?
