An open source bitmap converter program built with Open Frameworks

Want to show images on a JoyGamer or other Arduino powered SD Card reading, 128 by 160 pixel device? This little open-source program built with openFrameworks converts all kinds of images (e.g. .jpg, .png, .gif) into bitmaps (.bmp) of appropriate size and type to display on the Joy Gamer's little TFT LCD Screen. Adafruit sells these screens raw or with cool breakout boards .

The App

This is the cpp file that does all the work in this little app. There are 2 ways to make bitmaps.
1) Press spacebar and select an image from your computer. It will display in the window and you can press 's' to save it. This is nice but you can only make 1 Bitmap at a time. So we also developed option 2...
2) You can also create bitmaps from every image in a folder. Change the lines near the top of the file: 
directoryName = "/Users/samfriedman/Pictures/small/";        newFileName = "tl_";
Change the directoryName path to point to the folder with images that you want to make bitmaps from. The bitmaps will be numbered and have the prefix of the variable newFileName, so you may want to adjust that variable as well. Re-compile the project, run it and press 'd'.
