ImageIO PSD 到 PyQt QImage

Question

I am trying to display a photoshop image in PyQt. I have been using the python imageio module to load images and through a series of steps convert them to a QImage as below. This works for many different things such as.exr, .hdr, etc. However when trying to load a.psd I get strange results like rainbow colors all over the place and a lot of noise. It seems that something is going wrong within the conversion process, but I cannot find enough documentation online from FreeImage, ImageIO or PIL to explain what is going wrong.

Here's a simple example of the conversion process I am using:

import os
from PIL import Image
from PyQt5 import QtGui
import imageio, numpy

path = 'path/to/image.psd'

imio = imageio.imread(path)
imio_np = numpy.uint8(imio) # convert from 16bpc to 8bpc
im = Image.fromarray(imio_np)
im.convert('RGB')
data = im.tobytes('raw', 'RGB')
qim = QtGui.QImage(data, im.size[0], im.size[1], QtGui.QImage.Format_RGB888)

# then just apply that qim to a QLabel

Ok turns out this is easier than I thought. I found the answer here: Convert 16-bit Tiff image to 8-bit RGB . The problem was just converting from 16bpc to 8bpc, and I'll post that here in case anyone else has this issue.

import os
from PIL import Image
from PyQt5 import QtGui
import imageio, numpy

path = 'path/to/image.psd'

imio = imageio.imread(path)
if imio.dtype == 'uint16': # 16bpc
    imio = (imio >> 8).astype('uint8') # convert to 8bp with a bit-shift

im = Image.fromarray(imio)
im.convert('RGB')
data = im.tobytes('raw', 'RGB')
qim = QtGui.QImage(data, im.size[0], im.size[1], QtGui.QImage.Format_RGB888)

# then just apply that qim to a QLabel
