I know how to enter text using the preview monitor and position them in the picture ,but my question is,it is possible to transfer or copy a text from my computer harddrive and position them in the piture?
Normally you can use copy and paste for text or any windows objects like pictures or graphics. To do so from your windows document select the text, press the right mouse button and select copy go to your Magix software click on text entry use the right mouse button and paste also you can use hot key Ctrl C to copy and Ctrl V to paste.
If you need a permanent logo or text on the picture you must fix on it using a drawing software or a paint software like one from Magix or Windows. Test before the appropriate size.
