[REQ] Comments in rendered images

[OnoSendai]

Any half-decent image editor should allow you to view the extra information.

Can't see it in any of the ones I've tried, including the Gimp, which is certainly half-decent.

Gimp supports EXIF display since v2.3.9.... simply try using recent 2.4.0 RC2

[CoolColJ]

what about ACDSEE or the older versions?

I use it's thumbnail browser a lot. Shows lots of Exif data

Maybe even Window's thumbnail view with right click properties? It normally shows quite a bit of info. Even hovering the mouse over photos I've taken will show what camera was used to take it etc and then right click will show everything including exposure

[IanC]

In Gimp, it's view->info window, or ctrl-shift-i

That lets you read the comments in exif data, anyway.

In kde 3.5, you can see the meta data by right clicking on it.

[OnoSendai]

it's not EXIF data though.

[IanC]

It is the comments in the exif data, if you want to first check you're writing properly to the files.

Or you could download infranview, I know that will show exif data (press e I think). http://www.irfanview.com/

It's not Exif comments either.

The only half-decent solution I can think of is to add a little command-line switch to indigo, that will dump all metadata out of a specified PNG file.
e.g.
indigo_console.exe --showmetadata renders/im456456.png

render time: 456456s
samples per pixel: 45654

what the hell IS exif, then? xD

http://pmt.sourceforge.net/pngmeta/

The PNG & MNG Tools set has pngmeta, which is probably much like what you envision for the --flag extracting of said fields... if you don't want to add the display code to the indigo executable, we could just send people there...

Alternatively there are precompiled binaries for Windows and linux here: http://www.libpng.org/pub/png/apps/pngmeta.html

and yep, gimp-2.2.15 seems to only reads comment, no additional fields - and apparently only reads it's -own- comments; trying the PNG samples from the above toolkit, it reads nothing! Weird, that.

[IanC]

It's not Exif comments either.

Really? Because I'm setting the "JPEG Exif comments" in kde, and they are appearing in GIMP under 'comments'.

and apparently only reads it's -own- comments;

Not for me, see the attached image. [edit removed beacuse it's huge, will compress and re-up] [edit 2: re-upped]

Uhm that's gimp, but what did you set the comment with? If you set it with gimp, yes, gimp will read it back. That's what "it's -own- comments" meant. Try to set it with another app, perhaps ImageMagick, then open it in gimp - the Image Information window will go dumb and show nothing...

nonetheless if nik feels like adding PNG tEXt tag:value pairs the proper way, I'm sure we'll be able to extract said data one way or another. But not with gimp, for now anyway.

[OnoSendai]

Ok, i've added this feature.
Will be available in next indigo test.
the information is extracted like this:

great, that will be very handy

Great

Cool, cheers Nick.

Kram, thanks

HT, as Kram points out, I did it in KDE. That's what 'in kde' means :p
