Comments |
Expects the front-most image to be >512 x 512. |
System Requirements |
Should be compatible with all recent versions of DigitalMicrograph. |
Known Issues |
One problem when using text annotations is that they pick up the settings last used in DigitalMicrograph. If someone has set the text to white and you expect the annotations you are adding to be black, you may get unexpected results. It is therefore prudent to always set the font and colour before adding an annotation. |
