Photobox

My tif files will not display the transparency data when using Photobox. I tried the same files with CoreImage and it 'respected' the transparency.

Is there something wrong with my code?

pb = ximport("photobot")
c = pb.canvas(750, 750)
reload(pb)
 
#f = files("images/*.tif")
#image(choice(f), 10, 10)
 
tiles = ["_images/1.tif", "_images/2.tif", "_images/3.tif", "_images/4.tif", "_images/5.tif", "_images/6.tif", "_images/7.tif", "_images/8.tif"]
 
c.fill((255,255,255))
c.layer(choice(tiles))  
n = 3
 
for i in range(64):
 
 c.layer(choice(tiles))
 c.layers[n+i].contrast(1.1)
 w, h = c.layers[i+n].bounds()
 
 c.gradient(pb.LINEAR, w/2, h)
 c.layers[n+i+1].flip()
 c.layers[n+i+1].translate(w/2, 0)
 c.gradient(pb.LINEAR, w/2, h)
 c.merge([n+i+1, n+i+2])
 c.layers[n+i+1].brightness(random(4))
 c.layers[n+i+1].mask()
 
 c.layers[n+i].rotate(random(90))
 
 c.layers[n+i].translate(i*w/3, 0)
 
 if random() > 0.5: c.layers[n+i].flip()
 if random() > 0.5: c.layers[n+i].blur()
 
c.fill((200,100,0))
c.layers[n+i+1].opacity(60)
c.layers[n+i+1].hue()
 
#c.layer("_images/1.tif")
c.layers[n+i+1].opacity(40)
c.layers[n+i+1].overlay()
 
c.draw(100, 100)

I don't think there's anything wrong with your code, because from my experience, TIFF images aren't very nice with alpha channels. Try converting them to PNGs instead.

As impiaaa suggests, use PNG images with transparency. PhotoBot doesn't handle transparent TIFF, and at the moment we are not actively developing PhotoBot. If for some reason you can only use TIFF, I'd suggest switching to the Core Image libray.
