Turn snap to grid on.
Create a square, 2x2 pixels.
Turn off both outline and fill.
Export this clear 2x2 square as a 256 color GIF with transparency turned on.
Works fine in both XaraX 1.0d and XaraX1.
Now try it with a 1x1 pixel square.
In XaraX 1.0d, OK. In XaraX1, I get the attached error message.

Hi Al
I can't duplicate this error. It exported fine for me.

Hi Al,
No error when I export, using X1.
Sorry Al,
CND (Can not duplicate) tried a 1x1 transparent gif iwth and without snap to grid on. Works fine. See attached Picture... http://www.talkgraphics.com/images/smilies/biggrin.gif http://www.talkgraphics.com/images/smilies/wink.gif
No bang from me either...
Could someone explain why you would even want to do such a thing.

A 1x1 pixel transparent GIF is a useful tool in web design, or, at least it was until style sheets became so popular.
A lot of websites will still use a single 1x1 pix GIF in their page design and stretch it to different widths (say 130 pix, 15pix and 595pix) to ensure the integrity of column widths in a fixed-width table (in that example, a 130pix wide vertical menu, 15pix margin, and 595pix main content area in a 740pix wide table).
The most popular reason for using a 1 pixel .gif these days are for visitor tracking. The counter is off site.
Thanks for that info Guys - as you can see I am not really into web design but now I can see the logic of it.

Works for me Al. Sounds like a graphics card snafu?
By the way, here is a one pixel square at the maximum zoom, 25,601%.

Nicely drawn pixel Gary! http://www.talkgraphics.com/images/smilies/biggrin.gif
Hi Gary,
So... Is that 1 pixel with or without the black border?
Inquiring mind need to know... http://www.talkgraphics.com/images/smilies/biggrin.gif
You know John that would be like asking to find a Polar Bear in a snow storm. The only way you'd know he was there would be the yellow in the snow after he snuck up on you!! http://www.talkgraphics.com/images/smilies/biggrin.gif
He could have made a white pixel on a light grey background, then zoomed in and do a screen grab. Then it could be exactly 1 pixel X 25601%...
So there... Phffft.... http://www.talkgraphics.com/images/smilies/biggrin.gif http://www.talkgraphics.com/images/smilies/wink.gif
You got me back... Made me laugh this time...
Don't eat the yellow snow... http://www.talkgraphics.com/images/smilies/biggrin.gif
I was using the clear 1x1 GIF as a spacer, in the manner Daniel explained, not as a web bug which is a version of JohnR's example.
Guess something in my system/installation is unique. If I ever track it down, I'll report in.
Thanks for confirming that XaraX1 is OK.
Actually Xara X was the problem. Despite the fact it was tricky to repeat (as you can see from the other posts) we found in some very unusual circumstances that it would error with a 1x1 pixel transparent GIF. Fixed now and fix will be in the next build (the CD version).
Well, this just gets more interesting!
I just logged on to report that, after upgrading my ATI Radeon video driver, my clear 1x1 GIF problem is curred. But here Charles is reporting that XaraX1 can be the cause.
Maybe video drivers are simply one of the factors in making this problem difficult to experience/verify.
At work I have been documenting a large hardware device used by Pharma companies doing drug discovery. Half of the work is software API and UI documentation so I've been enlisted to help with software QA. I might as well change my email address to al@bugzilla.com given how many bugs I've been reporting. Makes me admire and appreciate the relative perfection of XaraX1's release.
Al I would say that you are right about the 3rd assumption. Older video cards and drivers may be the cause of this under Xara X1. If Charles found the issue valid and fixed it then no worries!! http://www.talkgraphics.com/images/smilies/smile.gif
