Useful Functions

These days I got chance working with phothoshop automation. Working with photoshop is really tough task for me because I am a simple .net guy. Thank god photoshop expert is here to help me.

I am also thankful to John Deurbrouck who has posted one article which helped me a lot. Using his idea I was able to write some of the functions, which is I am posting here.

using ps = Photoshop;

static ps.Application app1 = null;

Undo:

public static string undo()

try

{

if (app1.ActiveDocument.HistoryStates.Index(app1.ActiveDocument.ActiveHistoryState) - 1 > 1)

}

}

catch (Exception ex)

{

}

return "";

}
