[SOLVED]
Hello all,
I have found a way to display this and I have posted the solution below.
Unfortunately I did not find a way to actually display the DDS file so I
had to run a convert under the hood using Image Magick (great tool).
I then ran the TGA file image through the rungs of formatting the data to
generate a pixmap.
Anyway here are the functions I used to help my situation. I hope it helps
some people!!
*CODE:*
def convertDDS(self, ddsPath='', imageMagickDir='', overlay=False):
""" Convert the DDS files passed in to a tga file """
convert = imageMagickDir+'\\convert'
if overlay:
tempOutPath = r'D:\\magickOverlayOut.tga'
else:
tempOutPath = r'D:\\magickOut.tga'
subprocess.call([convert, ddsPath, tempOutPath])
return tempOutPath
def returnQPixmapFromImage(self, inputPath='', overlayPath=''):
# We turn out input paths into ImageQt objects for Qt to use later
inImg = Image.open(inputPath)
inputImg = ImageQt.ImageQt(inImg)
overImg = Image.open(overlayPath)
overlayImage = ImageQt.ImageQt(overImg)
# Creating the input image into a QPixmap
pix = QtGui.QPixmap.fromImage(inputImg)
pix = pix.scaled(512, 512, QtCore.Qt.KeepAspectRatioByExpanding)
pixHeight = round(pix.size().height(), 2)
pixWidth = round(pix.size().width(), 2)
# Creating the overlay images
overlayPix = QtGui.QPixmap.fromImage(overlayImage)
overlayImage = QtGui.QPixmap.toImage(overlayPix)
overlayImage = overlayImage.scaled(pix.size(),
QtCore.Qt.KeepAspectRatio)
# Check the image has an alpha channel so we can remove it for preview
if pix.hasAlpha():
qtFormat = QtGui.QImage.Format_RGB32
else:
# We need this for DXT1's/TGA's without an alpha. For some
reason it crashes the app
qtFormat = QtGui.QImage.Format_ARGB32
# Converting to QImage and removing the alpha then back to pixmap again
stripAlpha = QtGui.QPixmap.toImage(pix).convertToFormat(qtFormat)
myQImg = stripAlpha
painter = QtGui.QPainter()
painter.begin(myQImg)
painter.drawImage(0, 0, overlayImage)
painter.end()
finalImage = QtGui.QPixmap.fromImage(myQImg)
return finalImage, pixHeight, pixWidth
