CHAPTER 3: An Introduction to the Android Application Development Platform 93Next, we will want to save this new 144-pixel image data into the launcher_ic.png file in our drawable
resource folder to replace the standard green Android robot “placeholder” image that we had Eclipse
ADT generate for us earlier in the chapter.
- In GIMP, use the File ➤ Export or the File ➤ Export As menu sequences.
The Export option in GIMP allows image data to be “saved out” using image
formats other than GIMP’s own XCF format, which is what you will get in
GIMP if you use the File ➤ Save or File ➤ Save As menu sequences. Since
Android uses PNG format (among others) but does not (yet) support the
XCF format, we will be using the File ➤ Export As menu sequence shown in
Figure 3-17.
Figure 3-17. Use the File ➤ Export As menu sequence to export your downsampled icon to your project folder
Also notice that our transparent logo icon graphic has been scaled down from 200 pixels (shown on
the right-hand side of the screenshot). The Cubic interpolation algorithm has done a great job, as the
logo still looks really clean!
