Hi folks,

In 2014, the following message from wss...@gmail.com was sent to the
group:

Can any old-timer here help me contact them? There's no email address
on the website and Google Groups refuses to show it in full.

I have a question for them (I'd like to integrate their work in my
serial proxy).

Thanks!

Not an answer to your question, but the usual go-to solution to that
problem is https://github.com/digarok/b2d

Documentation is at https://www.appleoldies.ca/bmp2dhr/

Thanks for the pointer! Is it because it gives better results or is
there another reason?

(I'd want to add jpg/png support, and the code is... dense)

I personally don't tohgr so I don't know about its results. I guess you
have seen that the bmp2dhr link also talks about tohgr...

I personally don't know why about everybody uses bmp2dhr. I just wanted
make you aware of the fact.

Maybe https://github.com/digarok/buckshot is interesting to you...

Not really, as I'm looking for easy to transform into a lib to operate
automatically, even if the results aren't fine-tuned. But thanks anyway!

I've had some good results with tohgr with minimal modifications:

https://github.com/colinleroy/a2tools/blob/master/src/surl-server/hgr.c

(basically stripped main() and replaced it with img_to_hdr())

Here's my cat for example:

This might be a good opportunity to mention that I'm working on adding HGR conversion support to https://github.com/KrisKennaway/ii-pix/
It's a Python program and optimzes for image quality rather than encoding speed, so it might not be what you are looking for though.

Here are some example conversions (openemulator screenshots): https://photos.app.goo.gl/e3443CK29vdDsWpG9

Hi Kris,

The reason why I didn't mention ][-pix was not that it doesn't support
HGR so far.

The reason was rather the requirement of _both_ a Python environment
(with several non-standard modules) and the "right" C++ compiler to be
installed on the user machine doesn't make it the first choice for
simple integration.

And that my issue https://github.com/KrisKennaway/ii-pix/issues/3 is
still open doesn't make that better ;-)

However, from the image quality perspective, ][-pix is for sure the
best! Therefore, I used it for all my A2Stream cover arts.

Oh no worries, I wouldn't have expected it to be mentioned in the context of HGR conversions, which it doesn't yet (publically) support. I only started working on that yesterday in fact (in response to this thread!) and it turned out to be an easier modification than I'd expected.

Yes that's fair. I improved the installation process a while back but I could still use some help from someone familiar with python packaging to install "properly" without requiring it to be executed from the source directory.

Sorry I'd missed this - as I updated just now the dependency issue had already been fixed, and I fixed the dir creation issue.

Thanks for your support!

Cool, thanks :-)

Yes, that's the plan!

I'll try producing some sample videos soon. ][-Vision can be run in emulation now (I've confirmed it works in Ample on Mac, and it should work in AppleWin as well but I've not tested this) so that makes it easier to capture.
