[1.1.1] VNC: Region capture not correct: vnc.capture(someRegion) --- fixed 1.1.2 2018-03-06 build#120

[Julian]

problem: image is elongated or even turned up-side down

----------------- workaround
from comment #4
I have found a way to bypass this issue:
BufferedImage croppedImage = vnc.capture().getImage().getSubimage(xAxis, yAxis, width, height);
ImageIO.write(croppedImage, "png", new File("tempRead.png"));

... or some other means, that crops the needed region image from a fullscreen capture.

Hi,

I'm trying to read the text from a specified region, but what I've noticed is that, when I'm trying to see what's in that actual region, and capture that image, it becomes distorted.

If the region is higher than 185px, the image is elongated (second image in the screenshot).
If the region has the hight lower than around 185px, the whole text is messed up, and upside down too (the last image in the screenshot).

This is the code I've used:

Region tLocked = vnc.set(new Region(9, 170, 240, 185));
ImageIO.write(vnc.capture(tLocked).getImage(), "png", new File("terminal.png"));
System.out.println(tLocked.text());

Therefore, when trying to read text from the first scenario, I get nothing, and from the second scenario I get:
xfaaucxscs‘}5en:s_1_1:en: :

debug and have a look at the BufferedImage returned by
vnc.capture(tLocked).getImage()

... any differences?

What about something like:
tlocked.find(someImage)

does it work?

The BufferedImage looks the same as the second image in the attached distorted.png

I tried to do a find:

tLocked.find("loc.png");

But it didn't worked

FindFailed: loc.png: (118x8) in R[9,170 240x185]@S(0) E:Y, T:3.0
  Line 2782, in file Region.java

I have found a way to bypass this issue:

BufferedImage croppedImage = vnc.capture().getImage().getSubimage(xAxis, yAxis, width, height);
ImageIO.write(croppedImage, "png", new File("tempRead.png"));
String text = TextRecognizer.getInstance().recognize(ImageIO.read(new File("tempRead.png")));

@Julian
Could you give it a test?

Verified in 1.1.2 2018-03-10
The issue has been fixed, I can no longer reproduce it.

Thank you very much!
