I'm looking for an image format converter, but before you point to the standard converters, like .png to .jpg or .gif to .ico, let me point out that the format I want to convert from is machine language.
I have an old email archived, and it has an image shown in the form "iVBORw0KGgoAAAANSUhEUgAAAZQAAAEqCAIAAAC9ZzHyAAAACXBIWXMAAA7EAAAOxAGVKw4bAAAA . . ." (that's what I'm calling "machine language", though that may not be correct . . . but you get the point).
I know that particular image is a color photo. What I would like to do is take that "code" and convert it back to an image format, like .jpg or .png, so that I can view it.
I have a vague memory that I ran across something like that one time, but if I do a Google search on "image converter" all I get is the standard stuff that converts those .jpg to .png and .gif to .ico and such. That's not what I'm looking for.
And if I do a Google search on "binary images" all I get is stuff about black and white and pixels for two colors and such. So that's not it either.
Does the animal I'm looking for exist?
(BTW, my OS is Ubuntu, so Windows graphics editors are out. Well . . . I guess I can somehow manipulate it over to my Windows VM if I have to, but I'd prefer something in Ubuntu.)
