I had this problem before and have a sollution. You can create an string!
out of the image! which uses the same memory-area.
Example:
>> im: make image! 10x10
== make image! [10x10 #{
000000000000000000000000000000000000000000000000000000000000
000000000000000000000000000000000000000000000...
>> parse im [str:]
== false
>> str
==
{^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^...
>> change str "hello"
==
{^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@
^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^...
>> im
== make image! [10x10 #{
68656C6F0000000000000000000000000000000000000000000000000000
000000000000000000000000000000000000000000000...
You can give str to the library-function and it will change your image!. I
used this for a program.
Hope that helps,
