No idea what the to call this question?

Postby ChavezDelgado » Tue Aug 12, 2014 9:26 pm

Hi,

I'm new on the forums and fairly new to Inkscape to. I've spent a lot of time just messing around with various parts to see what results come from them. However I am now working on a logo for something and I've run into a problem. I know it'll likely sound trivial to veterans and please believe me when I say I tried to search the forums for an answer. The only problem is I have no idea what the action I'm looking for is even called. I'll try my best to try and describe the problem and I'm hoping someone out there understands and has a solution. Thanks in advance folks :)

I've added a screenshot of the project I'm working on. The two crosses are normally white but I changed one to black so you could see exactly what the issue is. In a nutshell, I want to get rid of the line that goes beyond the oval section of the image. Normally when the color is set to white you wouldn't even know there was any overlap but I'm worried that when I come to use this image in future (logo printing etc.) not solving this may become a problem. Once I get rid of the extra overlap part I would want to make sure the edge would blend into the overall oval shape.

TL;DR I need the bit of the line (black one for now) that goes beyond the oval to be removed. For the piece of line remaining within ideally its end would also blend into the rest of the oval maintaining the overall shape (oval)

Apologies if that makes no sense, I'm really struggling to find a way to explain this problem that has no name :/

Cheers,
Allan

Both lines in the X would be white but I've changed one to black for clarity of the issue

There are two main ways to achieve what you're looking for: Boolean operations, or clipping.

1) Boolean operations: This modifies your black shape so that only the part within the blue oval remains. Duplicate the oval, ensuring it is on top of the black shape. Select both, then use Path > Intersection. Do the same for the white shape, or alternatively use Path > Union to combine the black and white shapes into a single object before you do the intersection with the oval.

2) Clipping: This leaves the original object intact, but stops Inkscape drawing the parts of it that are outside the oval. Duplicate the oval, ensuring it is on top of the black shape. Select both, then use Object > Clip > Set. Do the same for the white shape, or alternatively you can group the black and white shapes together then clip them as one. You can use Object > Clip > Release to un-clip them if you need to.

Perfect, that is exactly what I was looking for. I highly doubt I'd have worked that out on my own.

Thanks a bunch, much appreciated :)
