Ah, I see what happened. There was a Microsoft Word document in my folder
of images. It was causing the problems. I had no error handling for
non-images.

Hmm, I made it a little further. Now I am trying to write a thumbnail to
disk. I have copied the code from StackOverflow. I am using this function:
(defn make-thumbnail [filename path-to-new-file-including-file-name width]
{:pre [(= (type filename) java.lang.String)
(fs/exists?
I wanted to see what Format strings I am allowed, so at the repl:
user (import 'javax.imageio.ImageIO)
javax.imageio.ImageIO
user (require '[clojure.pprint :as pp])
user (pp/pprint (javax.imageio.ImageIO/getReaderFormatNames))[BMP,
bmp, jpg, JPG, wbmp, jpeg, png, JPEG, PNG, WBMP, GIF,
gif]
and if I look here:
http://www.mkyong.com/java/how-to-write-an-image-to-file-imageio/
I see this example:
ImageIO.write(image, jpg,new File(C:\\out.jpg));
ImageIO.write(image, gif,new File(C:\\out.gif));
ImageIO.write(image, png,new File(C:\\out.png));
This is going to result in a pretty ugly thumbnail because you're missing
the hints java needs to do high quality resizing. Java's shrinking also
doesn't really have a nice smoothing mode.
I'd actually recommend you look into https://github.com/mikera/imagez. It
has a resize function in core
You definitely don't want a period in your format string.
Why are you calling(.drawImage g img 0 0 width height nil). What's the
nil for? I'd try dropping it.

Thanks for the tip about imagez. I wanted to get something basic working
today, but I'll give imagez a look tomorrow. As for now, I feel like I
should not give up till I have figured out what the problem is.

I found this:
http://stackoverflow.com/questions/3432388/imageio-not-able-to-write-a-jpeg-file
So I changed this:
imgtype (java.awt.image.BufferedImage/TYPE_INT_ARGB)
to this:
imgtype (java.awt.image.BufferedImage/TYPE_3BYTE_BGR)
and that worked for one image. The next image
Okay, everything works now. Apparently that last problem had something to
do with differences between OpenJDK and the SunJDK. I have:
java -version
openjdk version 1.7.0-ea
OpenJDK Runtime Environment (build 1.7.0-ea-b222)
OpenJDK 64-Bit Server VM (build 21.0-b17, mixed mode)
I don't recall
