Re: exec encoding

Hello,

Hello,

the exec command returns the output of the program. Like this:

image create photo -data [exec import -window root gif:-]

The output of the program is binary data and the image is wrong. The
above command works if the format is xpm (7 bit ascii). I assume the
output of the command is converted to utf-8. The following snippet works
correctly:

set f [open "|import -window root gif:-" r]
fconfigure $f -translation binary
image create photo -data [read $f]
close $f

Is there any way to get the exec way work?
Something like "exec -translation binary ..."

Not yet. This is a known issue, and solution similar to the one you propose is discussed in TIP #259:
http://www.tcl.tk/cgi-bin/tct/tip/259.html

For now, your pipe method is, AFAIK, the only correct way to go.
