Hello,

Sorry if this is a stupid question, New to all this. However trying to create an image. However when i export the finished product. (logo with a negative space behind it)
there is sections of white that curve along the Bezier lines that i can't remove.

Issue is this logo is all black and wanting to overlay this to other images. however I get these stupid white sections.
Hope this makes sense. I have attached photos to help explain

Any Idea's or pointers would be great, I could be doing something to simple and wrong. Only been using this for a week.

Cheers.

So this is the outline that export with portions of white on the inner side of the Bezier lines.



Are to try and put it in perspective when I overlay on to something else (I know black on black isnt the best example) you can see the white sections show up.

Welcome aboard!

Make sure your drawing has no white fill before exporting.
Inkscape renders solid white as the transparent background by default, try switching to checkerboard background in the document properties for a second check on the white fills (Shift+Ctrl+D).

I don't think that's technically correct.....  Or it might be correct, but reads in a way that isn't clear.  Why would switching to the checkerboard background help?  Because isn't the checkerboard visible even at 50%?

The Inkscape background, which shows up as white, by default, is in fact, transparent.  Unless you changed it, it likely is still transparent.  As far as I know, switching to the checkerboard background has no effect.  The checkerboard background was added as an option in Inkscape, because most other graphics programs use it, to indicate transparency.  And a lot of users like it.

Personally, the checkerboard bg drives me crazy.  For objects with very low opacity, I can't see them against the checkerboard.  For those tiny white areas (at the tip), I'm not sure if they would show up against the checkerboard.

But in any case, to make sure your background is transparent, you need to open Document Properties > Page tab.  Then around halfway down, look at the Background section, and click on the color bar.  If the  canvas background is opaque, the bar will be a solid color.  If it has any transparency, you'll see half of it is checkerboard.  But since you need to make sure it's 100% transparent, you need to click on the bar, which will open a small color dialog.  Make sure the A: slider (alpha) is all the way to the left, and showing a value of zero.

I can see some white areas - some tiny, some larger.  But we would need to see the SVG file to tell for sure where they are coming from.  I'd say Lazur's implication is correct, that at least some of the white areas are coming from a white fill on the paths.  But those tiny white marks are the tip seem curious to me.  So the SVG file can tell us for sure.

Background is not "rendered" transparent -if it was, you could see the other programs behind the window or the desktop.

I usually use that toned down checkerboard with blue you can see in my other screen captures.
If I want the background to be solid white explicitely, putting a rectangle behind the drawing.

Thanks for your responses lads, As this was my first post it had to be approved prior to posting so i didn't actually see these come through.
However Lazur, you look to be on the money with a solution. So I will try what you put together in the little video tonight.

Thanks Again
Mulder
