It's look like I should to use template function, but I can't figure out how to use it. Could anybody show example?

My code:

"abc" strings are not multiline.
Use """abc""" for that purpose.

Also perhaps next time test with a smaller file.. say 1 by 1 with no extra chunks.

If I wrap data with """ or ` .... ` I am getting same error. It's seems that problem that last charset is =

Create a range that would remove the newline characters from string, then decode from that.

std.file.write("output.png", Base64.decode(myimg.chomp));

The same error

chomp only trims the string at the beginning and at the end, not in the middle.

Anyway if you need to import a file inside your code probabily import works better.
Something like:


auto mystring = import("file.png");

So you don't need any decoding at runtime.

Can confirm, its \n and \r that is causing the problems here.

with:
std.file.write("output.png", Base64.decode(myimg.replace("\r\n", "")));

I am getting same issue. But it should remove all new lines...

ok split myimg value into another file, remove all \r and \n separately via e.g. tr.
Then read it in, that's what I did.
