I would like to save an image created by a script/applet but I don't know how to do it(efficiently). There is no img tag, just a container to hold the image. The SAVEAS TYPE=BMP works but that is overkill i.e. saving almost 7MB for the entire page vs only 0.5MB for the desired image. The direct screen command DS CMD=SCREENSHOT X=xxx Y=yyy is a little better as it only saves the visible portion of the page which can be partially trimmed with the SIZE X=xxx Y=yyy to just include the desired image.
A better solution (for me) would be to be able to fully specify bitmap region to capture, i.e. (x1,y1),(x2,y2). I'm not sure what the X=...Y= specs in the DS CMD=SCREENSHOT are supposed to do, but adding a WIDTH=...HEIGHT=... would do the trick if the X,Y are meant to indicate the center of the image, (as might result from the IMAGESEARCH command).
Thoughts???

Re: Saving arbitrary bitmap region
I'd like to see something like that as well.
Regarding the capture size, yes BMPs are large files. There should be left to the user which one to use: SAVEAS TYPE=JPG or SAVEAS TYPE=PNG, regardless of the browser being used (FF -> PNG only, Full page, IE -> BMP, not full page, iMacros -> BMP only, full page) I'm really looking forward to see iMacros, IE, FF -> BMP|PNG|JPG, full page!!
What I do in my macros to take screenshots is something like this
Once the macro finishes the !EXTRACT variable stores pairs of values such:
I feed that string to a custom function that will do the following for me:
1. Break the string into pieces
2. Load the BMP
3. Using GDI+ stamp the URL where that BMP was taken
4. Save the resulting BMP as JPG and remove the original BMP.
This saves loads of disk space in our server and also give us the added feature of having the URL embedded in the screenshot, a feature that iMacros does not implement.
Obviosly you will need the scripting version of iMacros to do this...

Re: Saving arbitrary bitmap region
I have forwarded your suggestion to the dev team (internal ticket# io132).
