Unwanted border with other texture and picture

[Giles]

I'm having trouble with Powerpoint, which insists on including an unwanted
border around a graphic I'm trying to use as a background.

I've created a texture in a graphics package and have saved it as a
full-screen-sized gif file (1024 x 768 pixels). In Powerpoint I've drawn a
rectangle the size of the screen and then, when formatting the Autoshape,
have chosen "No line". For the fill color I initially tried "Fill effects"
and selected my graphic as an "Other texture". However, this resulted in the
grahic occupying all the screen except for borders about 1 cm wide along the
top and left edges, which were filled with the default green rectangle fill
colour.

I then tried inserting the graphic as a picture. This time it had a white
1cm border on every edge.

I know it's nothing to do with my graphic size because I tried increasing it
and it had no effect. Has anyone any idea what's happening - and can you
suggest a solution?

Giles.

Addendum:

Sorry, when I said I tried inserting it as a picture I meant that I tried
this within the "Fill effects" area as a fill to the rectangle, not as a
separate picture instead of the rectangle. You may well ask, "Why didn't you
insert it as a picture, then?" The answer is that I did, and it does get
round the border issue, but I'm wondering if that approach may make the file
bigger (and also I'd like to understand what's going on in the Fill effects
area because I may want to use it for something similar in the future).

Right. OK. Deep breath... um, time to apologise.

Prompted by your message, I had another look at the image I'd created for
the background, and it turns out that the graphics package had created it
with a transparent 1cm border. I know I didn't actively do this, but judging
from my strike rate today I wouldn't rule out the possibility that it may
have been my fault.

Anyway, suffice it to say that it's my original graphic that's to blame, not
Powerpoint (no wonder I couldn't find a reference in the help files). Sorry
for having taken up you time.

By the way, if anyone's interested I have a great recipe for humble pie...
