[JohnFredC]

Please support the ArtRage ptg format in a future release.

As always, thanks for listening!

Please support the ArtRage ptg format in a future release.

Ok, could you send me some samples? Do you have specifications?

Hi Pierre

Here is a sample (1.1Mb), but I don't have any specs...

[maadjordan]

my first look at the example provided that it has pleanty of png and sort of bitmap images .. so i think i don't need much time to support and it can be handeled as psd in layers or pages..

This is good news!

I find myself using ArtRage (plus Wacom tablet) as a marker board on my 24" monitor: flow charting, brainstorming, etc. It wasn't intended for that use originally, but it works fantastic for that. Consequently I've many many of these files now and hope for XnView support.

We've just ArtRage 2.5 and I've added a new chunk into the ArtRage painting file format which is the rendered document at full size, in PNG format.
You convinced me to add it sooner, rather than later.

See the following C++ pseudocode. The chunk AR3_FilePreviewLargeOpaque has been added.
To avoid having to read the entire painting files earlier to 2.5 looking for that chunk (and not finding it) I can commit that the AR3_FilePreviewLargeOpaque chunk will immediately follow the AR2_File_ProjectThumbnailImage chunk. (So if you find the AR2_File_ProjectThumbnailImage chunk, and the very next chunk is not AR3_FilePreviewLargeOpaque, you can stop reading as the full-sized preview will not be there).

For painting files previous to the new release I'm afraid you can still only get the 200 x 200 thumbnail.

One day someone will convince me to write the entire compositing pipeline into a handy LIB file. One day...

Badly formatted C++ code follows, but if you send an email to andy@ambientdesign.com I can send you a nicely formatted CPP file.

I should also add...
There is a free Windows Shell extension dll available for download from ArtRage.com
Installing the ARThumb.dll extension will give previews in Windows File browsers if they're in Thumbnail view.

That Shell extension works great. Thank you for it!

Any news on this? Will XnView support ArtRage .PTG? I surely support this suggestion. Latest message here was july 2007, and the 1.93.4 does not seem to support to .PTG

You have ArtRage support in 1.93!

Hm... I can not see that it works. I checked the options -> system integration -> associations but I can not find ArtRage (.ptg) in the list. Tried on two different computers (one Vista and one XP).

Is it just me or has somebody else also problems with this?

EDIT: I use ArtRage starter edition, the free version - but I dont think it should matter.

Do you have enabled option/Genral/Display all formats?

Nooo... I knew that. Just checking...

PS Thank you, it works nicely now.

[Troken]

How come this is not enabled by default?
