Transparency with PIL and paste ?

[jean-Baptiste Cazier]

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

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)

# 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()
