Hello,
I try to work with the asset browser with python.
I can list objects in the asset browser, but I can’t find how to get the preview image generate by Blender.
Is it possible?
Most data blocks seem to have preview:
So probably that has something to do with what you are after.
If you generate a preview it seems to contain an image:
That image seems to be used in asset browser if I make whatever data block into an asset.
Thank you for your reply.
That help me a lot.
If someone need the full code, after reading Blender documentation and tryingdifferent things, I have done this :
def toRGBA(pixels, height, width):
img_data = np.zeros((height, width, 4), dtype=np.uint8)
for i in range(height * width):
pixel = pixels[i]
# Unpack the 32-bit integer into RGBA components
a = (pixel >> 24) & 0xFF
r = (pixel >> 16) & 0xFF
g = (pixel >> 8) & 0xFF
b = pixel & 0xFF
# Set the pixel in the NumPy array (row, col, channel)
row = height-1- (i // width)
col = i % width
img_data[row, col] = [r, g, b, a]
return img_data
def createImg(preview, output_path):
preview_data = preview.image_pixels
width = preview.image_size[0]
height = preview.image_size[1]
img_data = toRGBA(preview_data, height, width)
img = Image.fromarray(img_data, 'RGBA')
img.save(output_path)
You can call it with a preview object and a path for the generated image :
createImg(bpy.data.objects['Cube'].preview, "/tmp/preview_image.png")
