I am trying to use the toycamera filter in combination with -t. From what I can see there is a bug in the code that would allow this to work correct. Below is my command and the output.
$ toycamera -i 60 -o 150 -d 5 -s 10 -c 10 -S 2 -t ffa930 -a 10 in.jpg out.jpg
OUTPUT
convert: unable to open image `ffa930': No such file or directory @ error/blob.c/OpenBlob/2643.
convert: no decode delegate for this image format `ffa930' @ error/constitute.c/ReadImage/552.
I have tried to wrap the color in quotes, add 0x or # in front and of the color and nothing seems to work for it. Is it possible hex values are not valid? Any thoughts?
