Next revision of my draw app is released, here are the new features:

• “Smudge” tool — will smear the colors around, can be used to create a ‘watercolor’ like effect
• “Picker” tool — the standard ‘eyedropper’ tool, select a color from off of the canvas
• Color picker enhancements — L button now exits the picker, also shows the current selected color in top right
• Controls change — Change the current tool using the Left/Right buttons now.

Latest update

As always, I welcome feedback, and please send me your pictures as well!

Here are a few more images that I have drawn, using the new smudge tool, and/or the new fill tool. (FYI: All the images I post are resized to 50%, which is how they are displayed on the DS’s screen. I usually then link them to the full-size png, which usually doesn’t look as smooth, but has the advantage of being twice the resolution of the display on the DS)

Happy Tree	Waterfall

Three new features:

• Bucket Tool – using the ‘slow fill’ method I talked about. It’s not 100% perfect yet
• Eraser Tool – this needs some more work, if you erase slowly it does funny things
• Better color picker – Looks more like a normal color picker, and I included a greyscale bar to easily pick whites/blacks/greys.

Again, I’d be thankful if people could test it out and let me know how it works. I welcome all feedback / bug reports / etc.

Ok, I’ve packged up libpng and zlib for use on the DS. I also included a small makefile which should build both of them and install them for use. Please let me know if it does not work for you.

Basically, I only had to comment out one line in libpng (but man did it take me a while to find that line), in the png_zalloc() function, and then I changed the makefiles to use arm-elf-gcc instead of gcc (same for ranlib, ar)
