Hi Samuel,
Sorry for late reply I was on vacation.
You have asked for two images dummy.png and dummy1.jpg.
So for your reference I am attaching two images and
Also I am attaching the final out put. Please comment on
this.
RK.
Your dummy.png is quite wholly transparent, that's why the resulting
image is also transparent.
Here is how it works:
the two images are *combined* together, so the RGBA value of the
composed image is the 'multiplication' of the two images. (the two
images are not displayed one *over* the other).
It means that the final image gets the transparency of dummy.png.
dummy.png should be a mask : white where your want to see dummy1.png,
fully transparent where you want to see the background.
(and half-transparent where you want to *add* transparency to
dummy1.png)
Do you understand ? (my english is not very good...)
