Problems with pixel preview

Problems with pixel preview

Postby dalton565 on Tue Sep 09, 2008 11:35 am

Hey guys

im new to the forum and come to you for any advice you may have.

Basically i have an image(250x300px bitmap), and i want to reduce the size (eg 50% ) of the image so i have been looking at using the live trace. so i have been taking the bitmap tracing it and then saving the resulting bitmap.

the problem i am having is when it all goes well till i save it as a bitmap and then the image becomes heavily distorted and blurred. I need anti0aliasing off btw.

I have looked at the image at the reduced size and it looks fine, but when i click pixel preview (where it shows a preview of the rasterised image) it seems to rasterise very poorly. Let me give you an example, a pixel that is 1% black and 99% white, it makes this pixel black.

I have looked at exporting the image as an svg and trying to rasterise it better but have had no improvements as yet.

also looking at developing my own algorithm to rasterise the svg, but theres not alot of material out there.

Anyone have any alternate suggestions or ideas.

i would appreciate anything as i am pretty stuck as it is
