importing an empty svg image renders as filled
Hello
I have read the doc and I can see svg doesn't support grading. but I was surprised that an empty shape was rendered as filled on my screen. Attached is the small shape I'm trying to use. I even tried to make the 'triangle' openned and yet MuseScore still fills it up black.
Any pointer?

Maybe I didn't understand. Do you need an image as attached?

Thanks for the answer. It is good to know it works in a frame. In my case, I need to insert it in the score, at the same place a crescendo would be. When I drag it on the measure, it imports but filled. See attached picture, this is the same one you used. It fills up...

I think the problem is the image format, if you have graphics software check if you have the "transparent" option.
Does the attachment below also become filled?
Select the image with one click and check from Inspector the stacking order.

ok this works - what format did you use? is it still vectorial (like svg) or is it rendered? I have a feeling it is the latter since it seems to be a white background - and not just the 3 lines of the triangle. I reckon I'm just still used to vectorial graphic handling of my previous notation software (where I could stretch and adapt such lines that are quite important to my notation work)
The original shape I provided is not even closed, so transparency for filling shouldn't apply in svg if it stays a vector list, no?

*.png, I simply flipped the image with KolourPaint (standard on Linux) and used Inspector to adjust it

ah so that is a no-go. It is a raster and I need to keep it vector to be able to scale without loss of resolution. It is a creative way around making lines that do not exist in the software. Is there a planned support of pdf or native (aka not rastered) svg?

All png, mine, svg you can try.

ok, back to my original question then :) it doesn't seem possible to import an empty shape in svg. I think this is a rendering bug as the shape appears empty even in the file loader of add->image of the frame contextual menu, as shown in this screen capture. We can also see the result import at the top left (filled black)

ok good news: it was a bug in v3 but as I was ready to make a real bug report, i saw the alpha of MS4 and it is solved! They render properly there. So the alpha just gained another tester :)

In that case I assume it to be a Qt bug, in 5.9, solved in 5.15?

Try this image to see if it might be what you want.
I made it in Paint and made the background invisible in PowerPoint. Down load the image and drag it into a vertical frame in MuseScore to test. Drag it where you want and resize.
Works on my system. No idea if the background will stay invisible on your system.

In theory, SVG can produce a sharper image when scaling up larger than the original size and/or printing at high resolution. In practice, the difference isn't as big as it's sometimes made out to be, especially when actually printed.

indeed - until we can do arbitrary lines I will use this method to make a pattern and then stretch to match the gesture's length. and it will look nice (apart from the thickness that will be variable but hey, I'll see how I get on with MS4 which looks like an incredible update!)
