Creating Bubble Icons

Templates

Two gimp templates are stored on a file server:

roscd rocon_bubble_icons
make templates

Resizing Your Icon

Once you’ve found your icon that you want to embed in the bubble, open it in gimp and resize it to

• ~50x50 pixels (low-res template)
• ~250x250 pixels (high-res template)

Embedding in the Bubble

Open the bubble template you wish to use and make sure you have the Layers, Channels, Paths window open.

• Select the Embedded Icon layer
• Use the Rectangle Select Tool to select the entire turtlebot and then cut it from the layer.
• Go back to your original scaled down icon, use the same tool to select it and copy it.
• Go back to the template icon, paste into the empty embedded icon layer.

Optional:

• Move this layer up and down for best effect.

Saving:

• Precise: Use the File->Save as option
• Saucy++ : Use the File->Export option
• Save it as png type
• When flattening the image, a compression level of 2 seems to work well.
