hello and a happy new year.
When i export text as a giff from X pro and view it in my browser it has the dreaded jaggies, what am i doing wrong? I've looked through the help pages and the first 30 pages of posts on here and although I've picked up quite a bit can't get this right
cheers thrush
Hi Thrush,
Can you post an example or provide a link to an example image?
Before you export, check your 'View Quality' setting from the toolbar slider, or 'Window -> Quality' on the menu bar.
ideally you should have behind the text a bitmap of the background you will be placing it over on the web page. Do not select this when exporting.
This helps the blending in.
I have the anti aliased checked, I have tried to attatch the file but i am having no luck there either when i click on the manage attatchments box it highlights but I can't get anything to happen
instructions here - specifically post #3

ok i'll try again
thanks
Looks like 'Normal View Quality Setting' to me. Post your .xar file please.
Have you tried exporting as .PNG, with 'true colour + alpha' setting?
John
No, to the true colours and alpha question. Here is the xar file.
John PNG will work of course, however it a pity that PNG transparency is not supported in IE6 or below, so care must be taken when choosing this type for web images.
My attachment in post #2 is infact a GIF file, and shows that exported correctly with Xaras View Quality Setting ramped right up to 11 (AntiAlias) the text shows nicely. At Normal setting (10) is shows the same jaggies as thrushx.
This is a GIF image showing the results of different View Quality settings:

This is thrushx' GIF export

Below is thrushx's .xar file which I have exported as GIF. Making sure that View Quality is set to highest. (antialias)
Had the same problem myself, got it answered on TG :)
**EDIT oops - stepped in too soon .... sorry Steve. Didn't realise IE6 didn't like .PNG and should've realised that there was a reason for you not mentioning PNG straight away :o :)
John
Ok gents , now i'm making headway, how ever the text is still not as sharp as in xara, i coppied both of your replies back to xara and opened them to 500% they both displayed the same amount of jaggies but the xara text was pin sharp, is it not possible to export it at the same sharpness, please forgive my ignorance machine tool fitter by trade but i have the patience of a saint
You can't work backwards like that.
If you have exported the text as gif and then try to enlarge it/zoom in you will always get pixelation [jaggies] because a gif is a bitmap and not a vector. If you want it bigger you need to export the text as a larger size gif in the first place.
Hope that helps
When you import a rasterized image into Xara (bmp/jpg/gif/png are all raster images) and zoom in to 500% you will always see pixelization. Raster images are not scalable. Vector images are scalable and retain their 'pin sharpness' at any size.Quote:

When you do come to export and need to save it as a rasterized version, you must first size your vector appropriately. In other words. If your 'text' measures 200px x 100px in Xara as Vector and you need to create a 400x200px GIF file for your web page, first resize your Xara text to 400x200 THEN export.
I hope this helps.
(Steve J jumped in just before me - though we've both said more or less the same thing, between us I hope you see what we mean :))
understand, thanks.there's me thinking computers could do anything. would that work the other way . if i made my text large to start and reduced it for export would that keep it sharp?
Computers can do [almost] anything, but not without a knowledgable driver at the wheel ;)
Reducing a large raster will introduce softness/fuzziness. The best way to get precisely what you want it to 'create' it precisely.
as you can increase or decrease the text you make within xara before export because it is vector - you size it appropriately, as Sledger outlined - re-exporting it each time for different sizes
importing the [raster] bitmap and trying to resize that is what does not work
Gentlemen, thank you for your patience I have learned a lot, although it might not seem so to you. But trying to learn what these machines can and can't do along with what the programs can and can't do, throw in learning to type at the same time and it's easy to get confused, at least it is for me.
Give me a lump of steel anytime.
best Regards thrush
Glad to help :)
Hi Thrush,
When any program tries to create a bitmap from a vector, it has to sample the bits at that location. When you have a line going at an angle your line will pass through a location halfway and thus needs to be filled with something. If you have the color of the web page behind the text, then you will fill the half pixel with the background color.
The easiest way to get the page background to be a solid color/ the background color is to Ctnrl-drag your color from the color line to the page. That will automatically create another layer the same color as what you dropped in the background.
If you need a varible color or something more complex and just ask and we can help you with it.
Attached is a simple example of this and the .xar
Look ma... no jaggies...
