I was trying to use the good old bmp2asc program to import a bitmap into Layout.
But I couln't figure out a way to make it working under Win 7 x64.
So I gave up bmp2asc and I wrote my own script which can be run from within Layout and it also presents a GUI.
The file is attached to this message. Please post your questions here in case you have problems.
Enjoy!
