Do you mean the commandLine widget, that has the input on the left and the
output on the right, at the bottom of the main window?
While it does have a background color attribute, it doesn't perform the
same result as when a warning or error is generated (yellow/red).
It just outlines it.
For the screen cap, there are a couple solutions you could use.
A super duper basic way would be to do a viewport playblast to an image,
and then perform whatever cropping you want on the resulting image file:
cmds.playblast( frame=cmds.currentTime(q=True),
f="viewport.png",
fo=True, fmt="image", viewer=False,
c="PNG", quality=70, rfn=True )
Another way would be to use the API to get an MImage of the current
viewport. Nathan Horne has an example of doing this and writing to a file:
http://nathanhorne.com/?p=261
import maya.OpenMaya as om
import maya.OpenMayaUI as mui
image = om.MImage()
view = mui.M3dView.active3dView()
view.readColorBuffer(image, True)
image.writeToFile("viewport.png", "png")
But again, you will need to perform the cropping using your own lib.
And lastly, if you want to perform the entire process before writing to a
file, and you already happen to have PyQt4 installed for Maya, you can
transfer the pixel buffer over to a QImage:
import maya.OpenMaya as om
import maya.OpenMayaUI as mui
import sip
from PyQt4 import QtCore, QtGui
image = om.MImage()
view = mui.M3dView.active3dView()
view.readColorBuffer(image, True)
w,h = view.portWidth(), view.portHeight()
vptr = sip.voidptr(long(image.pixels()))
i = QtGui.QImage(vptr, w, h, QtGui.QImage.Format_RGB32)
trans = QtGui.QTransform()
trans.scale(-1, 1)
trans.rotate(180)
i = i.transformed(trans,
QtCore.Qt.SmoothTransformation).rgbSwapped().copy(0,0,300,200)
i.save("screencap.png")
What this does is gets the pixel array from the MImage, then creates a
QImage from that data directly. The data was in a bit of a different
format, so I had to flip it on X and then rotate it. Also, I needed to swap
the rgb channels into the right order. You can perform the crop you want
using that copy method. It takes the x,y points and the width height.
