Color camera support

[gmiller-whus]

Any info on when or if support for color cameras will be available? Any info on why it is disabled at this time? Thanks.

Any update on this one? Did you get it working? Thanks

[gmiller-whus]

Yes, I did get it working. I am now able to capture an image from a color camera using the “RGB8” format. I need more testing before I branch/merge the code.

Hi! have you tried your solution? Do you plan to commit your code?

Thx

[gmiller-whus]

Hi,

Yes, I have tries my solution and it works great with a color camera. I do not have a B&W camera to confirm that it still works properly that way.

I do intent to commit my code in the next few days.

Thx.

For those who run into this issue while the support for color cameras is not there yet, here's a quick fix:

Comment lines 224 and 225 on PyPylon/cython/factory.pyx Change line 251 to: img_data = np.frombuffer((<char*>img.GetBuffer())[:img.GetImageSize()], dtype='uint8')#+bits_per_pixel_prop[3:]) install pypylon with python setup.py install

This results in the different color channels being repeated in a single one channel image. The snippet below takes the picture and returns the image in BGR colors which can be directly worked on with OpenCV.

    cam = pypylon.factory.create_device(devices[0])
    cam.open()
    cam.properties['PixelFormat'] = 'RGB8'
    images = cam.grab_images(1)
    img = [o for o in images][0]

    out = np.zeros((img.shape[0], img.shape[1] / 3, 3), dtype=np.uint8)
    for j in range(img.shape[1]):
        c = int(j / 3)
        out[:, c, 2 - (j % 3)] = img[:, j]

@Wing0 I have an issue with your solution. the code return an error out = np.zeros((img.shape[0], img.shape[1] / 3, 3), dtype=np.uint8) TypeError: 'float' object cannot be interpreted as an integer

seems like I have to cast "img.shape[1] / 3" to int. otherwise Python stores it as a float and now it's working

As @Wing0 says in the next comment, I'm using python 3.6

[Wing0]

@Terrapon Thanks for pointing this out! You're probably using python 3.x whereas I have python 2.7.13 and division always returns an integer. Other than that, I hope it's working out for you.
