Transparency with PIL and paste ?

Discussion in 'Python' started by jean-Baptiste Cazier, Jul 23, 2003.

  1. Sæl !

    I am trying to rotate some text and paste it into a larger PIL Image.
    ( cannot use PyFT for some reasons)
    However I have a problem of transparency and my new images in a box
    shape are overlapping eventhough the test itself does not overlap.
    I would like to avoid that problem using the transparency of the image
    but without much success so far

    Below is my code for Python2

    Any help would be appreciated

    Thanks

    Jean-Baptiste


    #!/usr/bin/python

    import sys,math
    sys.path.append("/home/stat/Pygtk/PIL/")
    sys.path.append("/home/stat/Pygtk")

    import Image,ImageDraw,ImageFont


    def rotat(text,angle=70):
    """ Rotation routine
    returns the image and its size """

    color=(220,120,010)
    pangle=float(angle)*math.pi/180.0
    [x,y]=my_font.getsize(text)
    xy=x+y
    timage=Image.new("RGBA", (2*xy,2*xy),(255,255,255,0))
    draw=ImageDraw.Draw(timage)
    draw.text((xy, xy-y), text,font=my_font,fill=color)
    timage2=timage.rotate(angle)
    X0=int(xy-math.sin(pangle)*y)
    Y0=int(xy-x*math.sin(pangle)-y*math.cos(pangle))
    X1=int(xy+math.cos(pangle)*x)
    Y1=int(xy)
    t3=timage2.crop((X0,Y0,X1,Y1))

    return t3,X1-X0,Y1-Y0

    my_font=ImageFont.load('/home/stat/Pygtk/PIL/Fonts/helvR12-ISO8859-1.pil')

    #Create 2 new images
    im,x_im,y_im=rotat("Mest the Test with M",45)
    im2,x_im2,y_im2=rotat("new Test with T",20)

    # Create an empy image
    empty_image=Image.new("RGB", (500,300) ,(155,255,255))
    empty_draw=ImageDraw.Draw(empty_image)
    xs=0
    xs2=xs+30
    ys=0

    # Paste new images
    empty_image.paste(im,(xs,ys,xs+x_im,ys+y_im))
    empty_image.paste(im2,(xs2,ys,xs2+x_im2,ys+y_im2))
    empty_image.show()
