image_to_j2k not outputting to win32 console properly about openjpeg HOT 10 CLOSED

Could you propose a patch with your proposed fix ?

Hi,
I tried modifying the source-code to include those lines of code, but it failed. 
Maybe it was where I put them, I'm not sure. Instead, I have re-written all the 
print statements that I need to acertain a status of how the encoding is going. When

run in a console, it's exactly the same as before, just my app can now see what is

being output.

I tried image_to_j2k.exe with the current svn code, and the console (MSYS or windows
console, win xp) output is the same than linux:

torri@CARO-50BC2B3960 ~/svnroot/openjpeg/build/libopenjpeg/.libs
$ ../../codec/.libs/image_to_j2k.exe -i ~/ebuilder2.png -o ebuilder.j2k

[INFO] tile number 1 / 1

(there is a pause, then)

[INFO] - tile encoded in 1.145806 s
Generated outfile ebuilder.j2k

maybe the OP should verify again with at least openjpeg 1.4

Sorry it's been a while. I will give OpenJPEG 1.4 a go since I am now also rewriting
my app from scratch with VB.NET 2008.

A fresh start can always help.

Thanks for your input.

Hello again.

I have now tried v1.4 and still the same issue. I found the old forum posts I made
regarding this issue as I initially thought it was my app at fault. I have since rewrote
my app and the same applies. I fixed it by simply changing the fprintf statements in
the source for image_to_j2k to printf. Is this something you could do by default, or
will I need to modify each version myself?

Many thanks

one could maybe ad an fflush in the definition of the callbacks. But it adds overhead
and there can be problems if one use get() just after for example

Hi James,

Concerning the "fprintf(stdout, ...)", they are strictly equivalent to "printf(...)"
so renaming them should not change anything. Or am I wrong ?

Concerning the "fprintf(stderr, ...)", I'm not in favor of renaming them into "printf".
A better solution would be to redirect stderr to whatever you want, from your app.

no update in years, closing issue. Re-open if you can provide more input.
