I just want to know how can I do it, which functions and so on. About the position, I can't say which pixels exactly, so, Just give me an example and I calculate the number I must use

• Considering that 3 is similar to the horizontal flip of E and same thing with e to 9

Answer 1

Here is the script that will do the job. Most of it was written using the script listener And yup, the script listener code looks horrible, but after a while you can put snipets of the script listener code and turn them into functions. Which is what I've done. You didn't specify how big the image was so this script works on one that is 100 pixels by 100 pixels and will flip the selected layer. The magic numbers which specify the co-ordinates are used tin the select this line of code. Change that for your own needs.

If you are interested in learning how to code for photoshop then I suggest you use (and learn) javaScript. Oh and have a look at the script listener. Have fun.

//Set the preference to be pixels
app.preferences.rulerUnits = Units.PIXELS;

// Call the source document
var srcDoc = app.activeDocument;

// make sure we don't have anything selected first
srcDoc.selection.deselect()

// call the two selected areas
selectThis(33, 0, 33, 67, 33, 67, 100, 67);

//  flip the selection horizontally
flipEm()


// function SELECT THIS(top, left, right, bottom)
// --------------------------------------------------------
function selectThis(top1, left1, right1, bottom1, top2, left2, right2, bottom2)
