+## Background image
+
+The vector version of this is made in Adobe Illustrator and saved as the pdf jalview_dmg_background_layers.pdf
+
+This is then exported as 300dpi PNG to jalview_dmg_background_large.png
+
+This is then converted to the right size, with DPI information removed with ImageMagick
+
+```
+convert -geometry 500x461 utils/install4j/jalview_dmg_background_large.png  -strip  utils/install4j/jalview_dmg_background.png
