| 15:27.02 | andromeda-galaxy | for the raytrace background transparency set of tasks, how does rendering to png work? As far as I can tell, rt/rtedge only support rendering to pix and converting with pix-png, but the (current) pix file format doesn't seem to have anything like that... |
| 15:27.06 | andromeda-galaxy | (transparency) |
| 15:27.42 | YashM | When I did it, I had to render an image with a white background and crop it out in Photoshop |

| 15:28.47 | andromeda-galaxy | YashM: did you render with rt -o into a .pix file and then use pix-png to get a png before cropping it out? |
| 15:29.31 | andromeda-galaxy | there are some tasks now to make rt support transparent backgrounds which I'm interested in, but I'm slightly confused as to how to deal with it if pix doesn't support alpha-channel (which it doesn't seem to)... |
| 15:30.09 | YashM | no didnt use .pix |
| 15:30.51 | andromeda-galaxy | how? |
| 15:31.32 | YashM | i made a .png and opened in PS |
| 15:32.28 | andromeda-galaxy | how did you make the .png though |
| 15:32.42 | andromeda-galaxy | I couldn't find a .png option for cmd-line 'rt' |
| 15:32.46 | YashM | haha, just took a screenshot |
| 15:33.55 | andromeda-galaxy | ohhhh... well, then I'm stilll slightly confused about that task, since for file-output it doesn't seem to want to create anything other than pix (and trying to modify pix would be annoying, because backwards-compatibility + pix image dimentions are usually determined by filesize) |
| 15:35.18 | andromeda-galaxy | brlcad, d_rossberg: any ideas? |

| 17:39.58 | starseeker | you should be able to specify a png file by file extension, e.g. rt -o file.png model.g model |
| 17:40.11 | andromeda-galaxy | really? there doesn't seem to be any code in rt to deal with pngs |
| 17:40.21 | andromeda-galaxy | and the man page just says that -o always creates a .pix |
| 17:41.07 | starseeker | it should be calling libicv to deal with it |

| 17:47.48 | starseeker | did you try walking it through the debugger? |
| 17:48.12 | andromeda-galaxy | starseeker: so, as it stands currently, basically I've done the work for all the tasks that were already up, but I haven't committed all of it because a bunch of it still doesn't work |
| 17:48.16 | starseeker | it might be doing things in pix in memory and then handing that off to icv (that's what I would expect) |
| 17:48.28 | starseeker | oh, gotcha |
| 17:48.31 | andromeda-galaxy | and on top of that, even though a bunch of it is getting the correct result (naca), there are still valgrind errors |
| 17:49.23 | andromeda-galaxy | unfortunately, getting several hundred lines of converted-but-untested code into shape is going to take some time... I was planning to do some more of it if there were more tasks, but it not I'll do some more after GCI |
| 17:49.40 | starseeker | andromeda-galaxy: I'll see if I can persuade brlcad to add some tasks for it |
| 17:49.57 | starseeker | is half expecting andromeda-galaxy to fall asleep on his keyboard after GCI is over ;-) |

| 18:31.15 | andromeda-galaxy | maybe the header documentation should be slightly changed again, but the impression that I got from the first scan_fastf_t task (and what it was previously doing in the implementation) was that it should match the delim pretty much exactly |
| 18:31.26 | andromeda-galaxy | so multi-char delims are when the code wants that exact sequence of chars |

| 19:08.37 | ``Erik | andromeda-galaxy: the current intermediate format needs to be changed to be NOT pix, the pix format will stay the same |
| 19:09.02 | andromeda-galaxy | ``Erik: right, but then re-implementations of all of the tools that curently operate on pix would be desirable... |
| 19:09.20 | andromeda-galaxy | or, modify icv to make it do the right thing when going directly to png |
| 19:10.03 | andromeda-galaxy | ``Erik: by the way, does brlcad depend on readline/what's the recommended way to get a line? |
| 19:11.19 | ``Erik | andromeda-galaxy: icv is probably the right place to redesign the intermediate format, but there are many tools that need to be updated to use icv and even rt would need to get away from the addline approach and move to a per pixel (or array of structs) approach |
| 19:13.12 | ``Erik | I don't think anything in BRL-CAD uses readline (it works on windows, there might be a readline windows port that's tucked in somewhere, but I'd doubt it)... getline and scanf are probably the two more common ones.. um, 'nirt' and I think 'burst' have the capability, or something in src/conv |
| 19:13.37 | ``Erik | (nirt and burst have repl style prompts, iirc) |
| 19:14.30 | andromeda-galaxy | ``Eirk: ahh, thank... |
| 19:14.51 | ``Erik | just modifying icv in the rt approach won't get you true transparency... the best it could do is chroma-key on that 0,0,1 magic pixel (and we want real alpha transparency) |
| 19:15.10 | andromeda-galaxy | ``Erik: for ICV, the idea was that rt at least can use icv to directly write out png (without pix) |
| 19:15.23 | ``Erik | yes, and it does |
| 19:15.29 | ``Erik | sorta |
| 19:15.31 | andromeda-galaxy | so you could modify icv to use RGBA for PNG files & modify rt to give icv the correct information |
| 19:15.54 | andromeda-galaxy | (at least that's what I believe starseeker was saying) |
| 19:16.03 | ``Erik | you could, yes... then throw away the alpha when you save to pix |
| 19:16.49 | andromeda-galaxy | ``Erik: right. and then, eventually, if we have support for some awesome new better-than-pix format, just add that as an icv backend |
| 19:16.57 | andromeda-galaxy | and it automatically gets the transparency |
| 19:17.03 | ``Erik | then the intermediate representation, the data view.c is sending to libicv, is no longer pix (which is good) :) You could add MORE information, like using 16 bit color channels for hdr (which is better) |
| 19:17.11 | andromeda-galaxy | (by the way, isn't getline POSIX-only) |
| 19:17.28 | andromeda-galaxy | ``Erik: right, that's the general idea I had, anyway |
| 19:18.22 | ``Erik | getline is posix, it might exist on other platforms... winnt is sorta kinda posix complient, and that's the least posix of the supported platforms |
| 19:18.37 | ``Erik | compliant |
| 19:18.58 | andromeda-galaxy | right... where did you see getline() being used? I can't find it in C anywhere |
