Say I have an image of a rose which I want to trace:
I construct a few curvature shapes with it's stroke weight set to 5 like so:
Say I'd now like to see which stroke is placed over another, is there any way for me to do so?
Say my bottom layered stroke crosses a top layered stroke, it then might draw two little lines across the stroke like so:
Is there any way to set up such functionality? Or mimic it? It would help work like this a ton.
The program could get the order of overlap right by looking at the layer orders, which you would of course have to manually order yourself. But having a feature that enables me to see which shape is on top of which when they're overlapping would be great.

9 circles in a 3 x 3 grid with random lines on three of them connecting them to other circles (image)
I'm trying to more of less re-create the image above using react. The circles are div blocks and I have no clue how to go about drawing the lines that "connect" one circle to the other.
I tried using react-lineto, but it's simply not rendering anything when I use it. I can use the hr tag and use position absolute or something and just play around with where it's placed by toying with top and left props, but I don't think I'd be able to create diagonal lines.
Open to whatever packages or strategies you guys think could help me connect two dots (which are styled div blocks) with a line that could be vertical, horizontal, or diagonal.
Below is what I added to use react-lineto that didn't work. Straight from the documentation. I don't care to get react-lineto working as much as I just care to be able to accomplish this task in general.
<div className="A"></div>
<div className="B"><div/>
<LineTo from="A" to="B" />
I want to create this shape in react. I am able to code some of the parts but the border is creating issues.

What I am able to produce
Yo can use z-index property to achieve it.Set the z-index of vertical line to higher number than horizontal line and make sure both overlap each other at there intersection point.
I would like to create an sunburst effect as in the attached image. I want the flare to be from bigger to smaller (top to bottom)Click here for image. I can get the vice versa effect but i wanted something like in this image Click here for sample image. Please guide me how to create it. Thanks in advanced.
Make a star with a 0 inner diameter and as many points as you want
"bursts".
Put a rectangle over the star but not past the points of
the star.
Select them both and click divide in the pathfinder
pallet.
Ungroup the resulting paths.
Select every other triangle and delete it.
yay!!! sunburst.
So this is the effect what I want to get. Left and right parts of a label should have different filling/stroke colors (actually stroke size is also changed). And the proportion may change dynamically, and can be some position inside a letter.
I know I should override the paintEvent but still have no idea of how to do it.
Any ideas?
I am new to RRDtool. I generated a graph with grid(--grid-dash 1:0), a LINE(LINE1:rt#4e9a06) and I also have the area between the line and the x-axis coloured (AREA:rt#4e9a06 ). I notice the grid still shows up in the colored-area. I am wondering if there is any way to cover the grid with the colored-area.
Also, I am also wondering if there is any good-looking rrdtool samples/examples available online? Thanks.
I have no way of testing this currently, but here's what the documentation says (emphasis mine) :
[-c|--color COLORTAG#rrggbb[aa]]
Override the default colors for the standard elements of the graph.
The COLORTAG is one of BACK background, CANVAS for the background of
the actual graph, SHADEA for the left and top border, SHADEB for the
right and bottom border, GRID, MGRID for the major grid, FONT for the
color of the font, AXIS for the axis of the graph, FRAME for the line
around the color spots, and finally ARROW for the arrow head pointing
up and forward. Each color is composed out of three hexadecimal
numbers specifying its rgb color component (00 is off, FF is maximum)
of red, green and blue. Optionally you may add another hexadecimal
number specifying the transparency (FF is solid). You may set this
option several times to alter multiple defaults.
What about making an almost transparent grid with arguments like these (note the extra 7F parameter which translates to 127 in decimal):
-c MGRID#<hex triplet>7F -c GRID#<hex triplet>7F
It should still be visible in the background but be invisible (or barely noticeable) once any graph covers it.
Note that this answer from the developer of RRDTool says that the grid is always painted after the graph, so in the end you'll always have it in the foreground, your only solution is to either totally disable it or tinker with color/transparency parameters to make it invisible when covered by the graphed data.
