No reference for savePath() (Read 1172 times)

No reference for savePath()
Mar 12^th, 2008, 9:32pm

Hi. I'm using PImage.save() to save a screenshot. The problem is, I can't seem to just save it to the data folder, or whatever folder I want. I have to put the absolute path.

Now, the program tells me I have to either use createImage() or pass savePath() to save(). However, I can't find the savePath() docs on the reference page, not even in the extended one.

So, how do I use savePath()? Is the reference incomplete or am I just looking in the wrong place?

Thanks!

since save("file.jpg") will put it in the sketch folder, save("data/file.jpg") will put the file into the data folder, so long as you're running as a sketch inside the environment (things will change when you export, that's why it doesn't save to the data folder by default).

savePath() is primarily and internal function so we haven't documented it yet (though you can find it mentioned in the developer documentation on dev.processing.org). it's a useful enough function that it may be worth exposing it in the future.

My problem started because save() was not actually saving to my data folder.

I'm doing

Code:


if(fc==(60*3)){
			screenExp1=get(round(originX+40),
					   round(originY+40),
					   round(height0-80),
					   round(weight0-80));
			screenExp1.save(routeSS1);
			println("saved experience 1");
		    }

because if I do screenExp1.save("test.jpg") I get

"Runtime exception: PImage.save() requieres an absolute
path. Use createImage() or pass savePath() to save"

PS. By the way, I think it would be a good idea if we could copy and paste text from the message area

I have the same error message as acapulco. Any idea what is the problem?

PImage img = createImage(width, height, ARGB);
img = get(0, 0, 400, 400);
img.save("rendu_"+increment+".png");
increment++;
}
