I agree, for the double line I would use pattern along path.
For the waves, I would make an offset object of the coast line, fill it with some color, draw a couple waves of different length, and would use the spray tool (settings: without rotation or scaling, not spraying over transparent areas, not spraying over color boundaries) to put them into place.
I'm not sure if you already tried this, but it would be fairly quick.
Enable the grid and snap to grid.
With the Rectangle tool, draw one line of shapes like the example (below left). Group them Ctrl+G
Copy Ctrl+C and Paste in Place Ctrl+Alt+V, move into position, and repeat another once. Flip one of these pieces vertically
Select these two pieces, and Copy ...
Yes, there's a reasonably fast way!
Draw your shapes
Select both shapes, do Path > Combine or Ctrl+K. Note: the shapes will turn all one colour, but they are still there, just combined.
Draw a rectangle around both, and hit End (Send to bottom)
Select both pieces, do Path > Division or Ctrl+/. Each piece becomes a separate shape which can have its own fill ...
The problem is that the Greyscale Filter is an SVG filter, and these can't be expanded to vector only. When saved as a PDF, SVG filters must be rasterized because the format doesn't support SVG filters. So the only real option, if you want to keep everything vector, would be to recolour the artwork yourself by changing fill and stroke colours instead of ...
Draw the parts separately, align and combine to union:
Have all point snaps on, no other snaps!
Draw a rectangle.
Draw a triangle with the pen; it needs only 4 clicks; the 4th closes the triangle.
Drag the rectangle wider and lower, place it at the left side of the triangle (it snaps in the middle)
Combine (=Path > Union)
Personally I would use a dot matrix font for this, because it would be much easier, and look more like your example. There are many available online such as those here. I have no affiliation with that website.
Another method is to make a custom pattern in Inkscape, and use the pattern as a fill.
This pattern is made of one square with a black fill, and ...
SVG is a vector format used for vector graphics displayed on the web. SVG is the native format of Inkscape.
PNG is a raster (pixel) format used for images which are to be displayed on a screen.
The preferred format for printing purposes is PDF.
A PDF can both contain vector graphics and raster images.
Use File > Save As... and set Save as type to ...
Inkscape can manage only two arrows: at the begin and at the end of the path.
Your starting image is composed by two paths:
The knot Live Path Effect applies to one path only, so you have to combine the paths. This maintain one arrow at one extremity of the resulting path:
Now you can add the arrow to the other extremity of the resulting path:
If I get you correctly, you want this:
Switch to selection tool
Create an object that has the height you need
Copy the object to the clipboard
Click on the lock icon in the selection tool's tool controls
Select all the objects that you want to have that height
Select Edit > Paste Size > Paste height separately
Do you still need to script this, or is this ...
In Inkscape, the Object > Transform > Scale tab has an "apply to each object separately" option which could be used to make all selected objects the same dimensions.
Object > Arrange can be used to arrange selected objects in a grid.
Just be aware that Inkscape can't handle animated GIFs if you embed the images, they will become static. Although animated ...
You are right. Combining two paths basically turns them into one path. So, you can just use the Fill and Stroke panel, and in the Stroke Style tab, set an arrow head on both the start and end nodes.
There are two kinds of labels that Inkscape uses.The first one that the standard SVG (and also my compositor) doesn't care is inkscape:label(and each time you rename an object in the objects panel in fact that would be changed and it's for internal use by inkscape itself) and the one that my compositor parses each time is id :
So there is no need to have ...
A possible work around would be to apply a linear gradient to the stroke, sampling both objects' fill colours for each end stop of the gradient. However the gradient won't move automatically with the diagram connector. You'd need to reposition the gradient each time you moved the objects.
You need to convert the 2 open paths into a single closed path.
Select both paths
Path -> Combine (Ctrl-K). Now both segments belong to a single path object.
Edit nodes (F2).
Select (via mouse dragging, etc.) 2 overlapping nodes (the corresponding ents of each path).
/Join selected nodes/, which is one of the first options in the node editing toolbar.
If you have an object selected and you click a color in the bottom palette it will be the new fill color. Shift+Click picks a color and puts it to the stroke. It's written in the guidance text in the bottom.
I have version 0.92.4
Inkscape objects have 1 pixel wide fuzzy edge when they are rendered for the screen. It's the anti-aliasing and that's your problem.
A little bigger top object fixes your case. Insert for example a narrow stroke after the object is exactly in its place.
ADD due a comment:
Clipping has the same weakness. See an example:
Grey and red rectangles are ...
Replace the problematic clipped or scaled images with bitmap copies (Edit > Make a Bitmap Copy) before making the PDF.
The original clipped or scaled versions can stay in their places with no harm if you hide them in the Objects panel. Hidden objects stay out of the PDF.
Renaming or keeping the bitmap copies in another layer is essential to retain order.
Go to Preferences and take into use Geometric Bounding Box instead of Visual Bounding Box. The Visual BB shows how big shape there has been generated visible or under the hood when an effect is applied:
this rectangle has an effect.
The Geometric BB is strictly as wide and high as the original shape, the effect doesn't affect the size.
Not asked: With ...
This is more of a work-around that requires a good bit of manual operation, although someone more experienced than I may take the foundation and provide the accessory operation.
Convert your lines to paths using Path, Stroke to path. What was one a single set of nodes is now a series of double path nodes.
The above is a sample/test scribble with one true ...
For this specific problem, note that there's also the 'Rotate Copies' Live Path Effect available (Path > Path effects > + > Rotate copies) which allows you to rotate everything by mouse on the canvas.
And then there's also the 'Polar Arrangement' tab in the 'Arrange' dialog (Object > Arrange).
Both of these are easier to use for circular arrangement than ...
Also try the Knot LPE in combination with the Pattern along Path LPE:
a grid of duplicated and evenly spaced (arrange dialog) paths, combined to a single path
a rectangle turned to a path
To create this from the two base parts, do the following:
Apply the Knot LPE to the grid (Path > Path effects > + > Knot)
Switch to node tool. Click on the ...
