I have several pictures in my thesis. I want to draw arrows with text over these pictures. After that I want to scale the picture, but the node position should adjust to the scaling and arrows, and text-size should not change!

Here is my example:

every node/.style={font=12pt},
remember picture,
transform shape
 \node[anchor=south west,inner sep=0] (Bild) at (0,0) {\includegraphics{images/Bild.eps}};
  \node (a) at (28,44) {Hello};
  \node (b) at (54,63) {};
 \draw [
  line width=2mm,
 ] (a) -- (b);
\caption{This is an example} \label{Fig:Example}

So when I scale with

the image
is scaled, but also the font is scaled very small !

How can I scale the picture without changing the font and arrows ? While that the node coordinates should be adjusted to the scaled pictures (same position) !

Okay here is what I have so far:

    \node[anchor=south west,inner sep=0] (image) at (0,0) {\includegraphics[width=1\textwidth]{Bild.eps}};
    \begin{scope}[x={(image.south east)},y={(image.north west)}]
        line width=2mm
        ] (1,1) -- (3,2);

But I am working in TikZEdt. It is very hard to adjust the arrow by setting the nodes with the cursor. I got a very small green rectable, which represents the size of the arrow o0

How can I make this rectable bigger so that it is easier to adjust / set the position of the nodes for the arrow ?

Okay here is what I mean:

enter image description here

  • Scale the Picture
  • Keep arrow and font size (= document size)
  • And keep Position of the node !!**

The picture is the output how I want it (I edited it with Photoshop)

So how can I create such code that give me the following: - Scaling the Picture ("Latex"-pic in example) with scale=XXX - Keep arrow and font size (= document size) - And keep Position of the node !!** ???

You could just scale the node or the \includegraphics, can’t you? It also would be better to use coordinates relatively to your image node, say \tikzset{x=(Bild.south west), y=(Bild.north west)} (which would work in your simple case).

You can zoom things in tikzedt. – Harish Kumar Nov 8 '13 at 23:05
Could you include a picture of what the desired output is? – Tom Bombadil Nov 8 '13 at 23:10
