FYI,

I encountered the same temp file related error as Ray on OS/X 10.5.8. The fix Austin posted worked.

Very helpful script Ian, thanks.

@Ray

It seems that one or more of the components in the script have changed.

If you’re still interested in this script, here is how you fix it:
line 149: Remove the -t (This will put the temporary files into your current directory, but it seems the the -t option produces an unexpected output name)
line 206: Change ‘mktemp’ to ‘mktemp crushed-XXXXXX’

Again, this makes all of the temporary files in your local directory, but the script cleans up afterwards.

Hi Ian,
I’m still seeing this error. I should have everything I need installed.

bash-3.2$ ./googletilecutter-0.10.sh -o 15 -t 1812,1924 -z 15 image.jpg
Using advpng for compression.
Padding image …

Renumbering and compressing tiles …
ls: /var/folders/RP/RPcPqaqMGsahjBfs7JB0l+0Nfzw/-Tmp-//map-XXXXXX.NtN1jQ0D-tile*: No such file or directory

Any ideas?

OK, It works! I have a minimal linux installation, so ImageMagic took some tweaking to install. But it works at the command line – and I totally agree, command-line’s the best way to go. Thanks for sharing this useful scritp!

Hi Robert. When using BASH in scripts, I prefer to interface with ImageMagick using the command-line scripts, as I did with my tile-cutter. The command-line client is great in that you can apply many effects and transformations in a single line.

ImageMagic has many versions to interface to various languages (Perl, tcl, ruby, …). But, I don’t see one for bash, or shell scripting at all. Which one should I get?

Thanks,
Robert

Romulo, the only way that would probably happen is if you installed Cygwin and managed to install ImageMagick on it. I have no experience with the latter, so I can't be of much help. Sorry.

Can I use the command in windows?

How do I do that?

Excellent little tool.

I found that I had to rename the file with no extension to get a .jpg to be tiled on a mac OSX-10.5

There is a small bug in this when you give it an image with power-of-two dimensions where it will create one more tile than required (since it always rounds up).

I changed:

width=$((`echo $dim | sed -e “s/x.*//”`+$padX))
tileWidth=$(($width / 256 + 1))
height=$((`echo $dim | sed -e “s/.*x//”`+$padY))
tileHeight=$(($height / 256 + 1))

to:

width=$((`echo $dim | sed -e “s/x.*//”`+$padX))
tileWidth=$((($width – 1) / 256 + 1))
height=$((`echo $dim | sed -e “s/.*x//”`+$padY))
tileHeight=$((($height – 1) / 256 + 1))

and it seems to work fine.
