Re: Using captured values in beanshell scripts

Gaurav,
On the surface that sounded like the winning combination, resulting in the
expression doing something like this:
...
File ofile = new File("screen0.png");
BufferedImage bi = script.getProperty("screenBuf");
try
{
ImageIO.write(bi, "png", ofile);
} catch (IOException e) {
...
Which did create a file, containing a png image, but alas is not the
screen that is being displayed on this phone emulator's display (it's an
empty png of the correct size of pixels however.) I'm now going to make
an extension to the Step() object because that appears to be the only
mechanism that is capable of the level of abbot.robot control I need. I
didn't want a custom version of Abbot but I guess I'll be delivering
one...
Thanks for the pointer though, it did clarify how to use script variables
from sample steps within expression steps.
Best regards,
Wayne Motycka
Unless somebody else has some

but I'm needing a few pointers on how-to with regard to
screen capture from scripting.
Thanks!
