ValueError: unrecognized mode in takeSnaphot()

[Diob]

if bpp = 32

the mode is set to AGR. This in an invalid and not recognized mode. There seems to be something wrong in the next line where the sorting is done. if sorted is removed, Then the mode becomes RGA

[dtmilano]

Can you enable debug by setting DEBUG = True in adbclient.py and copy the debug information here?

It works if I force the mode and argmode to RGBA. However the colors do not seem right then.

Give AndroidViewClient 4.7.1 a try. It should detect your problem and generates a warning message instead of taking the incorrect alpha specification into account. You device tells its framebuffer is 32bpp but with 0 alpha bits. BTW, which device is it? There's something wrong with the framebuffer implementation.

The issue persists in version 13.4.0. Here is what I am getting:

Traceback (most recent call last): File "android_view_client_example.py", line 94, in <module> takeScreenshot(device1, device1Serial) File "android_view_client_example.py", line 79, in takeScreenshot device.takeSnapshot(reconnect=True).save('/sdcard/uiengine/bugreport/' + deviceSerial + '_' + date + '.png', 'PNG') File "C:\AndroidViewClient-master\src\com\dtmilano\android\adb\adbclient.py", line 790, in takeSnapshot image = Image.frombuffer(mode, (width, height), received, 'raw', argMode, 0, 1) File "build\bdist.win32\egg\PIL\Image.py", line 2333, in frombuffer File "build\bdist.win32\egg\PIL\Image.py", line 2265, in frombytes File "build\bdist.win32\egg\PIL\Image.py", line 2229, in new ValueError: unrecognized mode

Can you attach the script you are using? Also, info about the device, android version, etc. so the problem can be reproduced.

Thank you for getting back to me. Here is the following code I used:

`def takeScreenshot(device, deviceSerial): timestamp = time.time() date = datetime.datetime.fromtimestamp(timestamp).strftime('%Y%m%d%H%M%S') device.shell('mkdir /sdcard/uiengine/screenshot') device.takeSnapshot(reconnect=True).save("/sdcard/uiengine/bugreport/" + deviceSerial + "_" + date + ".png", "PNG") print("Screenshot has been taken")

takeScreenshot(device1, device1Serial)`

The device I am using is the H871 (LG G6 AT&T) with Android version 7.0.

You can enable DEBUG in adbclient.py (line 53):

DEBUG = True

and check the debug messages produced. This will help us understand the problem better.

[dtmilano]

Also, in your script you can do

import com.dtmilano.android.adb.adbclient
com.dtmilano.android.adb.adbclient.DEBUG = True
device.takeSnapshot(reconnect=True).save("fimage.png")

and check the debug output
