Can I presume correctly that there is no tool to automatically draw a curved line (similar to the straight line tool)? I have tried to use the Spline Mask tool by drawing a curved shape, then repeating the same shape and moving it a few pixels over from the first shape, but using the subtract button rather than add, for a resulting fairly thin line-like shape (the unnecessary portions have to be deleted), but have found that is difficult and imprecise in its application. And my freehand curved lines look, at best, like a very bumpy road. Any suggestions??

Re: Drawing a Curved Line
There is no curved line tool. The only work-around I can think of is to use the spline tool to create a mask and then the Edge transformation to turn the edge of the mask into a line. I don't expect the results to be particularly good from this technique, however.

Re: Drawing a Curved Line
Hmmm... Hmmm... There are curves, then there are curves...!
1) Create a Curve Line image using MS Paint on a 50% tone background with an initial preference Line color/width...
2) Open an Input image and the Composite-Hard Light transform with the Curve Line image as the Overlay and Alignment = 3-point (shift/rotate/scale/shear)... ...Use points 1 and 2 of the Input image to locate curve end points... ...Use point 3 of the Input image to shape/skew/invert the curve...

P.S... ...originally I had thought about suggesting that the curve be added to the Input image using MS "Paint.exe" to simplify the workflow but by using PWP's Composite-Hard Light transform, the Input image's: color bit depth, color profile, meta data [EXIF/IPTC] and file type should be preserved.

...
The following Curved Line image with 2.5, 5.0, and 7.5 pixel wide lines was created in PWP using the Line transform and the Fan transform with Curvature=25.0... ...Feel free to download and use with no restrictions...
To use:
1) increase or decrease curvature with the Fan transform with a 50% gray tone fill background...
2) Paint over the non-preference line widths with a 50% gray tone Paint brush...
3) When used as the Overlay image in the suggested Composite-Hard Light transform in the OP... ...relocate if necessary the 1 and 2 Alignment points to the prefered curve ends...
4) Line color can be changed in the resulting Composite-Hard Light transform image using the Flood Mask Tool with an Invert; then Paint with a color of choice [as long as the composite image area is not black next to the line]...
Wavy lines are easiest created with the likes of MS Paint... ...reconizing that the output image may be limited to 24-bit sRGB colors with no comments or profiles and possible compression artifacts...
...enjoy...
