[Question]
  [
The goal is to output or display an image with an € (euro) sign according to the following specs (ignoring the border of the sign).
![€ sign](https://i.stack.imgur.com/neCQE.png)
Source: <http://en.wikipedia.org/wiki/File:Euro_Construction.svg>
Rules:
* The program / script must take the height of the `€` sign in pixels as an argument (empty space around the sign is optional)
* The `€` sign can't be drawn as or from a character, directly (it's forbidden to `print` the `€` in the image) or indirectly (calculating [`8364`](http://www.fileformat.info/info/unicode/char/20ac/index.htm) then displaying it in a HTML page)
* The output does not need to be saved to any file, it can be displayed then just shown as a screenshot
* [Standard “loopholes”](http://meta.codegolf.stackexchange.com/q/1061/14215) are forbidden
* Shortest code wins

## Mathematica, ~~193~~ ~~183~~ ~~177~~ ~~173~~ ~~169~~ 166 bytes
Yay, maths! I'm plotting the region that satisfies a certain (rather complicated) set of inequalities:
```
e=RegionPlot[(1<Abs@y<3||c)&&{x,y+12}.(d=2{-5Sin@40°-6,m=5Cos@40°})*{x+15,y+1-2Sign@y}.d<0||c&&x<2m/.c->100<x^2+y^2<144,{x,-15,9},{y,-12,12},Frame->0>1,ImageSize->#]&
```
Usage is `e[height]`, e.g. `e[100]`:
![enter image description here](https://i.stack.imgur.com/m2UhF.png)
Or `e[200]`:
![enter image description here](https://i.stack.imgur.com/rpFwz.png)
You may notice, that the sharper edges are slightly rounded off. That's because the region can only be plotted by sampling the points in space, and Mathematica doesn't sample each pixel by default. The sampling resolution can be increased by adding another option `PlotPoints->#` (which uses one sample per pixel), which adds **14 characters**. I don't recommend running it with that option, because it significantly increases runtime and barely increases visual appeal beyond `#/4` or so. Hence, (after approval of the OP) it is not included in the score.
Here is a slightly ungolfed version:
```
e[height_] := (
  angle = 40°;
  d = {-5 Sin[angle] - 6, 5 Cos[angle]};
  RegionPlot[
      (Abs[y] > .5 && Abs[y] < 1.5
        ||
       r > 25 && r < 36)
    &&
      {x, y + 6}.d > 0
    &&
      {x + 7.5, y + .5 - Sign[y]}.d < 0
    ||
      r > 25 && r < 36 && x < 5 Cos[angle] 
    /. r -> x^2 + y^2
    ,
    {x, -7.5, 4.5},
    {y, -6, 6},
    Frame -> False,
    ImageSize -> height
  ]
);
```
Note that in the golfed version, I've scaled the coordinate system by a factor of 2 to avoid the `.5`s, but it turns out that the character count is actually identical.
Here is an explanation for how I worked out the formula. I divided the shape into two regions. One contains the ring and the stripes and is cut off to the right with the `BCDE` slope and to the left with the `IJ` and `GH` slopes (more on that later). The other contains the same ring, but is simply cut off at the *x* coordinate of point `D`. The conditions for the two regions are combined with `||`, which acts as a set union here.
The ring is just defined as `5 < r < 6`, where `r` is the distance from the origin. `r²` is easier to work out though (`x²+y²`), so I'm using `25 < x² + y² < 36` to get all the points in the ring.
The stripes are between `±.5` and `±1.5`. We can handle both stripes at the same time, by taking the modulus of *y*, so the stripes (of infinite length) just fulfil `.5 < |y| < 1.5`. Again, to take the union of the stripes and the ring, I'm just using `||`.
The interesting thing is probably how to get the "masks" though. Point `D` has an *x* coordinate of `5 cos 40°`, so the mask taking care of lower edge (combined with the ring only) is just `x < 5 cos 40°`. This can be applied via set intersection which translates to `&&` in logic.
The other masks are the really tricky part. First, let's get the slope of `BCDE`. We can easily construct points `C` and `D`, as `(0, -6)` and `5 (cos 40°, sin 40°)`, respectively. The vector pointing along the line is then just `D - C = (5 cos 40°, 5 sin 40° + 6)`. To apply the mask on the right, I only need to figure out if a point lies to the left or the right of that line (let's call line vector `p`). I can figure this out by taking the vector from `C` to my point of interest and projecting it onto a vector *perpendicular* to `p`. The sign of the projection will tell me the side the point is on. Obtaining the perpendicular vector is pretty simple in 2D: flip the coordinates and reverse the sign of one of them. That's the variable `d` in my code: `(-5 sin 40° - 6, 5 cos 40°)`. The vector from `C` to a point of interest `q = (x, y)` is `q - C = (x, y + 6)`. The projection is just the scalar product (or dot product) between `q` and `d`. The way I chose `d` it happens to point to the left, so I want `d.(q-C) > 0`. This condition applies the right-hand mask.
For the left-hand mask I can use basically the same idea. The slope is the same and therefore so is `d`. I just need offset my point from the lower-left corners of stripes instead of from `C`. Those have coordinates `(-7.5, 0.5)` (upper stripe) and `(-7.5, -1.5)` (lower stripe). So that would call for two independent rules for the two stripes. However, note that all points affected by the lower mask are in the lower stripe and hence have negative *y*. And all points affected by the upper mask have positive *y*. So I can simply switch my offset using `Sign[y]` which is `1` for positive and `-1` for negative `y`. So my offset point becomes `(-7.5, -0.5 + Sign[y])`. Otherwise the mask works just like the right-hand mask. Of course, this time the projection needs to be negative. So, naively that would be something like `RH-projection > 0 && LH-projection < 0` (which is also what I originally had in the code). But we can shorten this, because multiplying a positive and a negative number has to give a negative number, so it's just `RH * LH < 0` (where `RH` and `LH` are the respective projections).
That's it. Putting it all together leads to the following logical structure:
```
(
  (is_in_circle || is_in_stripe)
  &&
  is_between_left_and_right_mask
)
||
(
  is_in_circle && left_of_edge
)
```
Just to be clear, the coordinates in my explanation refer to the construction diagram given in the challenge. As mentioned above my code actually multiplies all of them by `2` - I changed it to save bytes, but the byte count is actually identical, and I couldn't be bothered to revert the change again. Also integers look nicer.

**In BBC basic, all graphics are handled at the low level using machine-specific ASCII control characters** (but some high level commands are also available for the common ones for convenience.) The ones used here are 22 (change display mode) 29(change origin) and 25, equivalent to the PLOT statement, which takes an additional action parameter (draw line, circle, triangle, etc. in background/foreground with relative/absolute move) before the X and Y parameters.
**So all I have to do is send a load of characters to the VDU controller.** values terminated in semicolon are 16 bit. others are 8 bit. **The total number of bytes sent to the VDU controller is 91**, though that in itself would not qualify as an answer because by that stage the size is hardcoded.
The obvious place for the origin is the centre of the circle, but there are actually more commands involved in producing the bars. So I shifted the origin down 1.5 to the bottom of the lower bar, which reduces the number of fractions and negative numbers required. It remains on the vertical line with the centre of the circle, which is important because the line E starts from this vertical line.
Actually, I only had to calculate 3 numbers off the drawing: the top inner corner of the C shape (5 cos 40, 5 sin 40 + 1.5) = (3.8302,3.1394+1.5) = approx (12/3.1, 4.6) and the gradient of the line E:x/y=3.8302/(6+3.1394)=0.4157 = approx 1/2.4
As I only have the free evaluation version (interpreted), I take the symbol height as user input. If you buy the full version (29.99GBP) you can compile and then read the command line with `w=VAL(@cmd$)/12`.
**Ungolfed code**
In the golfed code, there is only one VDU statement, but in the ungolfed code I break it down into several for clarity. Also, because BBC basic is little endian, the combination `p,0,` can be golfed to `p;` but I left it ungolfed for clarity.
```
  INPUT h
  w=h/12                   :REM w is the width of the line, which is 1/12 the height of the symbol, hardcoded at 900.
  s=w/2.4                  :REM s/w is the gradient x/y of line E. s is the horizontal offset of the top and bottom of the ends of horizontal bars
  p=25                     :REM VDU p,action,x;y; is the equivalent of PLOT action,x,y

  VDU p,159,h/3.1;4.6*w;   :REM draw circle in background colour, ending at the upper inner point of the C shape.
  VDU p,0,9*s;9*w;         :REM move relative along slant gradient, 9 spaces in y direction, to define the upper cut on the circle
  VDU p,87,h/3.1;-19*w;    :REM draw triangle in background colour, based on the last two points and the absolute point specified here (vertical line for lower cut)

After seeing @ThomasW's answer, and considering my program carefully, I realized that I could do it even better.
The tokenized version is equivalent to this: 
```
h 120 div dup scale
75 60 translate
0 0 60 45 -50 arc
0 0 50 -40 40 arcn
closepath
-71 -5 moveto
-75 -15 lineto
19 -15 lineto
23 -5 lineto
closepath
-71 15 moveto
-75 5 lineto
27 5 lineto
31 15 lineto
closepath
fill
```
An explanation of the optimizations:
First off, I converted my first solution into a union of some simpler subpaths, rather than one path circumscribing the entire thing. I borrowed Thomas's method of inputting a parameter, which is much better than what I had had.
Then I multiplied all the coordinates by 10 and rounded everything off to give me just integer coordinates. I also rounded off the angles, and converted the two large ones to equivalent negative angles. This conveniently makes every single number fall between -128 and 127.
And then I tokenized *everything*. Each operator can be represented with a two-byte sequence each. And because each number can be represented by a single signed byte, each one *also* becomes only two bytes. The only part I couldn't do that with was the `h` at the start, but it too is only two bytes, just the `h` and a space after it.
Run it as:
```

## New: Even shorter versions!
Using encoded user paths, I have managed to reduce the program size by a few bytes. Each of these programs is equivalent to the first one, producing identical output:
92 bytes:
```
hexdump -C euro.ps

0000005c
```
Which is equivalent to:
```
h 120 div dup scale
75 60 translate
{
 {-75 -60 45 60
  0 0 60 45 -50
  0 0 50 -40 40

  31 15}
  <00 07 08 0A 01 03 03 03 0A 01 03 03 03 0A>

While this is only using SVG stuff, it heavily relies on lax HTML parsing and has to be served as HTML. Strict SVG would require a lot more bytes.

Save as `euro.ps` and run with Ghostscript like
```
gs -dh=80 euro.ps
```
![Euro sign, 80 points, rendered by Ghostscript](https://i.stack.imgur.com/fa5Fp.png)
```
gs -dh=20 euro.ps
```
![Euro sign, 20 points, rendered by Ghostscript](https://i.stack.imgur.com/xtT44.png)
As there is no such thing as a pixel in PostScript, that height is interpreted in points instead. I calculated +6 for the switch on the command line.

# PHP, ~~432~~ ~~435~~ ~~367~~ ~~356~~ 334 bytes
(Edit: Apparently IJ and GH are supposed to be parallel with BCDE. Now fixed)
This script outputs an SVG image, but will serve it as `text/html` by default. I think most browsers will treat this as an HTML web page containing an embedded SVG image. It seems to work OK for me anyway.
The height of the image is passed as a query string parameter. (Note: the byte count includes a newline character at the end of line 3, which is necessary for this to work properly).
```
<?php $x=$_GET['x']/12;$a=$x*5;$b=$x*6;$c=$x*7;$d=$x*12.4884;$e=$x*2.2863;$f=$x*5.5;$g=$x*.4157;$h=$x*6.5;$i=$x*7.5;$j=$x*12;$k=$x*11.3302;$l=$x*9.1628;$m=$x*8;$s=$x*12;echo<<<Q

### Updated version (~~367~~ ~~356~~ 334 bytes):
`preg_replace_callback()` is a much more efficient way of scaling the numerical values. This code produces the same output as the original version. (Edit: Further reductions thanks to [Einacio](https://codegolf.stackexchange.com/users/13870))
```
<?php
echo preg_replace_callback('/[\d\.]+/',function($m){return$m[0]*$_GET['x']/12;},'<svg width=12 height=12><clipPath id=c><path d=M12.4884,0H2.2863L0,5.5,0.4157,6.5,0,7.5V12H11.3302V8H9.1628z /></clipPath><g clip-path=url(#c) fill=none stroke=black stroke-width=1><circle cx=7.5 cy=6 r=5.5 /><path d=M0,5H11M0,7H11 /></g></svg>');

This just defines the outline by appending path elements based on coordinates I calculated with the help of GeoGebra, and then fills the outline.
I saved a few chars by adding shortcuts for `lineto` (`/l{lineto}def`) and the origin of the circle (`/o{0 0}def`).
To specify a different size, add a command of the form `*height* *width* scale` after the first blank line.
When run on its own, this draws the euro sign in the bottom left-hand corner of the page of the default page size. Just save it as `*anything*.ps` and view it with a document viewer.
Here is an image of it at the default size, rasterized to a little over 90 pixels per inch:

```
This is the same technique as @minitech's [answer](https://codegolf.stackexchange.com/a/26714/11259). But the .svg data comes from here, which is much shorter: <http://commons.wikimedia.org/wiki/File:Euro_symbol_black.svg>. ImageMagick converts the vector data to .png data at the requested scale and pipes to xview.

# POV-Ray (370 bytes)
I couldn't figure out how to render the same vertical area and preserve the aspect ratio at the same time, so I decided to go for the correct height and its up to the user to render only in 4:3 format
```
camera{angle 9 location 102*z right x*8 up y*6 look_at 0}
light_source{99*z color 1}
plane{z,0 pigment{color rgb 1}}
#declare b=difference{box{<-5,-.5,1>,<8,.5,1>}box{-2,2 rotate-67*z translate 9.4*x}}
difference{union{torus{5.5,.5 rotate 90*x}object{b translate y}object{b translate -y}}box{<-3.83,-5,-3>,<-7,0,3>}box{<0,7,3>,<-4,-2,-3>rotate 23*z translate-2.5*x}}
```
run with `povray.exe /RENDER euro.pov -w600 -h800`

# Processing, 232 bytes
Processing doesn't really allow taking in command line arguments since it is so specialized for drawing, but my function takes in the parameter as height to compensate. Coordinates are hard-coded/approximated from the image above, and the entire canvas is scaled based on the input parameter to get drawings of arbitrary sizes.
```
void E(int h){scale(h/12,h/12);noFill();strokeWeight(1);arc(7.5,6,11,11,0.7,PI*2-0.7,OPEN);noStroke();fill(0);shearX(-PI/6);rect(3.2,4.5,9,1);rect(4.4,6.5,8,1);shearX(PI/6);fill(255);rect(11,6,9,6);triangle(8.75,6,12.25,6,12.25,0);}
```
# Ungolfed + entire program
```
void setup()
{
  size(575, 500);
}
void draw()
{
  background(255);
  E(height);
  noLoop();
}
void E(int h)
{
  scale(h/12,h/12);
  //Main "C"
  noFill();
  strokeWeight(1);
  arc(7.5,6,11,11,0.7,PI*2-0.7,OPEN);
  //settings for other shapes
  noStroke();
  //the two bars
  fill(0);
  shearX(-PI/6);
  rect(3.2,4.5,9,1);
  rect(4.4,6.5,8,1);
  //bottom cut of "C"
  shearX(PI/6);
  fill(255);
  rect(11,6,9,6);
  //top cut of "C"
  triangle(8.75,6,12.25,6,12.25,0);
