Illustrating Rainbow with Clone tool in Inkscape.
Rainbow and clouds.. by ~rockraikar on deviantART
After some gap, I'm back again. This post is about drawing a rainbow. There are actually two ways you can do it. One is by creating a rainbow color gradient and fill a semi-circle with it. The other is by using the tiled clones tool. Tiled clones happens to be one of the most powerful & interesting tool in Inkscape and here I am trying to draw a rainbow with it..
To start with, select the Spirals tool (F9 key) and draw a semicircle.
Let the settings be:
turns:0.50, divergence:0.00, inner radius:0.00.
Adjust the width, height and stroke width as in the image.
Now select the stroke color as the one with '?' (question mark :paint is undefined) in the stroke paint tab of fill and stroke menu. We need to do this because for changing colors of clones using clone tool it is necessary that the paint is undefined for the object. Now,the arc/semi-circle will be invisible.
Next is the cloning step.
Keeping the arc selected,
Go to edit->clone-->create tiled clones. The following settings needs to be updated:
Symmetry:P1 simple translation.
7 rows and 1 column
Shift: for X all the values are zero. for Y the per row field should be -98.5
Scale: scale X per row is -1.6, scale Y per row is -0.7, all others are zero.
Color: Initial color be red, for per row field change the H value to 13.5. Rest all should be 0.
We wont be using rotation blur & opacity so we can leave them as they are.
Now press create, your rainbow is ready.
Give it a little blur and decrease its opacity.
You have your Rainbow. You can add a few clouds like the ones here. Apply a little blur to these clouds and it will look a bit realistic.
Happy Inkscaping...
Thanks,

If you have just downloaded Inkscape, the first thing I would advice is go through the tutorials in the Help menu to make yourself comfortable with the interface & tools(even I learnt the same way). Then if you want more you can go through tutorials at http://inkscapetutorials.wordpress.com . Screencast of inkscape tutorials are present at http://screencasters.heathenx.org/
A basic thing you need to understand is the difference between svg file and bmp files. svg is a type of image called as vector image and bmp is of type raster image. You can get a simple idea about them here.(http://raikardesigns.blogspot.com/2007/09/raster-and-vector-images.html)
Now if you have bmp files and want to convert it to svg, you can use the 'trace bitmap' functionality in the path menu of Inkscape. Drag .bmp file into Inkscape window. With the image selected, go to menu PATH->TRACE BITMAP. Select the COLORS radio button and then UPDATE. Adjust the number of SCANS as required and press OK. You will have a SVG (vector representation) of your bmp (raster) file.
Unfortunatly I wan't sucessful in trying to make the rainbow... this what the inkscape returned:

Now I adjusted the width and height, but the rainbow still doesn't look like the one you've created...
Neat tutorial. Thank you.
Thanks for the help, and great tutorial :)
Thanks anyway :) I'll definitely be trying more of these in the future :)
