I have found a way to view such bitmaps:

First, you need to download and install GIMP
Next, find your Bitmap object in MAT, right-click on mBuffer field, in the popup menu choose "Copy" -> "Save Value To File" menu item and save value of this array to some file
give extension .data to that file
launch GIMP, choose "File" -> "Open", select your .data file and click Open button
"Load Image from Raw Data" dialog will appear. Here you need to set correct parameters for your bitmap
first, choose "Image type" as "RGB Alpha" (most Android resources have this image type, but you may need to experiment with other image types)
second, set correct Width and Height for your bitmap (correct dimensions can be found in the memory dump)

At that point you should already observe preview of original image. If you didn't, you can try to change some other parameters in "Load Image from Raw Data" dialog.

NOTE: to get a width and height of image you can look at mWidth and mHeight fields in MAT.
