Export DPI setting

[AnimationDog]

Hello,
I am new to TvPaint and I absolutely love the drawing feel of this software. My Question - Is there a way to export from TvPaint and choose the DPI?
I am making the switch from paper to digital animating and most of my film is in an older program called Animo. If I bring my TVPaint drawings into Animo at 300dpi or 400dpi they align perfectly with my existing paper drawings. I know I can use photoshop to change the DPI, I would love to skip Photoshop and go directly from TvPaint with a choice of DPI. Is that possible?
Thanks much!

I don't think this is possible within TVP. But a batch job in PS should do the trick without too much of a hassle.

Animo? The original one from Cambridge Animation Systems? How can that still be running? I was a beta tester for that in the 90's ...

Well I'm currently starting on DPI. The notion of Dot-per-Inch is related to the papier size in inches (S) :
DPI x S = Pixels

Which means that if you want to change the DPI "setting" of your TVPaint project, you have to expand or shrink the picture. As a consequence, there is a chance that you get blurrier pictures when you export.

Yet if you start a new project, you can still use the above formula to compute your project dimensions in pixels !

Yes, Cambridge Animation Systems - Animo 6. I have had it working under windows 10 for a number of years now. It does have it’s glitches, most of those I have figured out by now. The batch rendering is much faster on the new computers and the extra ram is great. I also have Animo running on my Wacom Mobile Studio pro.

“I was a beta tester for that in the 90's ...” I started using Animo at the end of the 90’s

I have been using Photoshop to change the TvPaint exported image DPI from 72 to (300 or 400). The pixel count stays the same (3840x2160 for example) I only change the DPI. I think the dpi for Animo is important since it is from a time when scanning was the main process for importing the drawings.
I was just hoping to save the Photoshop step if I could. It would be great if I could set the DPI when exporting from TvPaint. If that is not possible then I will use Photoshop for that step.
Either way TvPaint has a great natural drawing feel and works nicely with my process.

Interesting ! So it's not only about the picture dimensions. Would you mind sharing one sample with me ? Exported from TVPaint - then updated with Photoshop ?

It's probably some metadata that is set, we've been trying to figure this out for a couple of time but we needed a concrete case.

You could easily do that with just Photoshop - create a new file with some pixel dimensions and a DPI setting, then another with same pixel dimension, but different DPI.

Thanks for the advice, I prefer to focus on the code and get real samples from real users.
Remember that I'm a software developper !

Into which format do you export the pictures ?

[slowtiger]

If I remember correctly, Animo uses TIFF.

Thanks again for spending the time to figure this out!

The file type can be Tiff, jpeg or png. I have 2 png images in the link below. I export them with peg holes at the top – Animo uses that to align with my existing paper drawings.
Both images are 7680 x 4320, 1 is 72dpi From TvPaint, 1 is 400dpi converted in photoshop.

Another interesting note.
7680 x 4320 @ 400 dpi
5760 x 3240 @ 300 dpi
3840 x 2160 @ 200 dpi
All are the same size in Animo (19.2 x 10.8 inches). The 400 dpi file of course has more crisp detail.

You're welcome Actually we use your example to improve the DPI management in TVPaint, so thanks you too

So you agree that it's tricky

Indeed : 7680/400 = 19.2 and 4320/400 = 10.8 but I assume that if you choose another dpi resolution, Photoshop decides to reduce the size in pixels.

So here's what I can see about the pictures you sent :

Obviously TVPaint adjust the print size to (pixels/dpi) :
7680 / 72 = 106.6 inches, aka 2709mm
4320 / 72 = 60 inches, aka 1524mm

So at least, I think I know what to do !

"So at least, I think I know what to do !" That's great!

At the moment, Japanese users often use paper as well,
and it is inconvenient for us to set all the files exported by TVPaint, jpeg, png, psd, etc. to 72dpi.
I would be happy if it could be resolved.
