Hello,

I have image (logo) in Inkscape which contains two colors and also have custom color palette with 64 colors (these are colors which are supported by LCD screen where logo will be rendered). When I export image to bitmap it will do antialiasing on exported image without considering used color palette, so it contains much more colors. Is it possible to do export to bitmap with keeping colors only from opened color palette?

I have very little experience with vector editor, so I hope my question make sense.
Thank you for your help!

Export at a higher resolution than needed (2-4x). Open it in an image editor, resize it down with no antialiasing and save it as a 64 color png. Maybe convert it to 64 color first if your editor supports an indexed mode.
This generally works although you might have to clean up a bit.

Yes, this is something what I was doing, but without antialiasing the resulted image has still just 2 colors, so the angled edges looks bad. So I would like to keep some sort of smoothing or antialiasing, because I believe in that 64 color palette are enough colors for much better result. If this is not possible in Inkscape, is there please some bitmap editor to recommend, which supports antialiasing algorithm on custom color palette?

The image is converted to the right colors even from the beginning. It is just white logo on blue background. I am using paint.net or Zoner Studio as bitmap editor but I didn't find solution to this. I don't want to do it manually in pixelart form of course.

It is possible to disable antialiasing in Inkscape. I'm not sure at what stage of the game you need to disable it - whether you should disable it before you draw the image, or only before you export it. But you can experiment.

Document Properties > Page tab, at the bottom.

Although.... While disabling it should prevent the extra colors, it might not be acceptable in terms of how the image will look. The smooth, clean lines will be gone. Depending on the image, it's possible you won't notice the difference.

Inkscape 1.0 will allow for a couple bit depth settings for PNG: http://wiki.inkscape.org/wiki/index.php ... PNG_images

Turning off antialiasing for the display makes no difference for PNG exports, it's pretty easy to check this, but of course I am running the standard version of Inkscape so this may not apply to special versions, if there is a version where this is different I would definitely want to use it (unless of course it's only available to developers).

One might think that with AA turned off for onscreen display at least "make a bitmap copy" might produce an aliased image, capturing directly from the draw buffer, but that is surprisingly not so.

Lazur has done a lot of research and has some great threads on this topic that people who have been here for a while might be familiar with.

druban, your wishes have come true: http://wiki.inkscape.org/wiki/index.php ... PNG_images (the prerelease is a bit unstable, though, esp. with text)

And the pony???

I like how the notes say "Definitely not released yet"

We had ponies in the user chat today... Here's one for you: (sorry, i wanted to insert the UTF-8 one, but the forum refused to add it)

(when searching for this, this made me doubt the sanity of the utf-8 committee: http://www.fileformat.info/info/unicode ... /index.htm)

That is very surprising. What's the point of being able to disable it, if you can't export an image that way?

I wonder why? Would it be considered a bug, or is there some reason for it, or explanation?

I guess it was only implemented for speeding up rendering, not for export.

Oh, I see. I never thought of it like that. I thought it was to allow users to draw without it, something like a pixel editor, maybe.

Well I wonder if a basic screenshot tool would "see" it? Testing....

Windows' Snipping Tool "sees" it.



Interesting....
