Re: Sharpening export PNG images
Greg, have a look over https://www.talkgraphics.com/showthr...DA-Web-Exports.
This handles scaling and storing the PNG fall-back for display in non-SVG capable browsers.
Acorn
P.S. Add a comment there to nudge Xara to implement SVG rendering direct from the design.

Here is an image of the issue.
Left is xara at 100% and the right is the pc using the exported PNGs

And here I enlarged 2 of the icons you can see more anti aliasing on the exported image

Re: Sharpening export PNG images
One thing I have seen that may help me is, if I export the images as a web site then pick out the saved PNG's they match the screen

Re: Sharpening export PNG images
try changing the xara view quality to 'full colour' before you export you vector to png - that will then export your vector as a PNG without any anti-aliasing - then if there is an issue with anti aliasing being 'compounded' that may fix it
the ringed image was so exported from vector, then reimported at 100% zoom:

in my first post in this thread I had blipped over the fact that these are very small images
like egg said you have to be very careful at such a size - there are programs that will have special function for this, but not xara
i think what you are seeing is the compound effect of exporting the image with antialias and then reimporting it and viewing it in xara with screen rendering antialias turned on - the effect of this is negligible at normal image sizes but at very low sizes it is seen
are you exporting the web page and viewing the pngs in another app, if so that might support such a view....

Thanks Acorn!
That's great advice.

Re: Sharpening export PNG images
Couple of points I didn't make in my earlier posts Tim:
1. If you're creating pngs to a set pixel size always set your units to pixels in Xara, not cm's. You can immeadiately see that your 'calendar' icon is 31px wide x 32.2px high, which will make a bad image. Set the width to whole pixels i.e. 32px
2. I use the following settings on exporting an image from Xara.

Many thanks I did not see that.
Cheers Tim
Re: Sharpening export PNG images
Just to add that making sure the images are exact pxs and exporting the images using "Export supersite" produced images that do not degrade.
Thanks all
Tim
