Don't want aliasing?

Hi,

This is easy probably except for inexperienced people (=me),

But I don’t remember what I did differently, (except for I scaled those last 2 pngs to 11%) but I want those sharp edges as in starblue,

how to reproduce it?

Please have a look here:

/Any advice welcome!

Hi.

How did you make these stars? I experienced quite some ugly AA due some filters and wasn´t able to get rid of them: “Exterior glow” for example “smoothes” out the original image some times some times not.

Have you tried to convert you graphic via “Object->Convert->To Image” already? See if this helps.

Cheers

Frank

Your examples seem to have been magnified to 600% or more. For a better quality, sharp-edged image, do everything in Intaglio.

In Intaglio, create the image and save as a JPEG. When the JPEG is displayed in a web browser, the image will look the same as the original artwork.

If you want a very small image, scale the original artwork to the desired size before making the JPEG.

Thank you Frank and Ivan,

convert your graphic via “Object->Convert->To Image”

That didn’t change much, I think because my artwork was a simple 1 - layered graphic only ( a star),(with gradient).

create the image and save as a JPEG. When the JPEG is displayed in a web browser, the image will look the same as the original artwork.

If you want a very small image, scale the original artwork >to the desired size before making the JPEG.

Alright, my stars are a bit “sharper” now, so this helped.

Although - wondering -
is there a quality - difference if we use png instead of jpeg
(esp. cf/ the edges)?

The examples were created in Intaglio.

The artwork was saved as a JPEG and a PNG. The files were opened in separate Safari windows and a screengrab taken. This was opened in Preview. As you can see, there’s virtually no difference between the JPEG and PNG versions.

If you modify a JPEG and then Save As a JPEG, the quality will probably decrease. I tried it, but couldn’t see any difference. This is more of a problem with photographs. Screen resolutions differ, so this could also be a factor.

JPEG is a ‘lossy’ format. This means that when a JPEG is saved several times, information is lost and the quality decreases. PNG is a ‘lossless’ format which does not suffer from a drop in quality. Google PNG and JPEG to learn more about this subject.
