| 00:06 | < Tarinaky> | Ahah! |
| 00:06 | < Tarinaky> | It's -e not -p. |

| 02:39 | <@ToxicFrog> | Tarinaky: possibly a stupid question but, uh, why are you using inkscape for this and not something designed for batch processing like irfanview or imagemagick? |
| 02:41 | <~Vornicus> | or, if you're doing vectors, postscript and a makeoid. |
| 02:41 | <~Vornicus> | (I had great success for that.) |
| 02:58 | <~Vornicus> | I also discovered that adobe's stuff has js automation but I wasn't a huge fan. |
| 03:03 | <@rms> | I'd have thought it'd be whatever Flash is. |
| 03:03 | <@rms> | (Since that's related to EMCAScript somehow) |
| 03:10 | <~Vornicus> | So you can (if you're that crazy) get the entire creative studio toolchain at your beck and call. |
| 03:18 | < celticminstrel> | Okay, so rotating an array without copying it probably won't happen. |

| 03:41 | < Tarinaky> | ToxicFrog: Don't know how to use postscript. |
| 03:41 | < Tarinaky> | Already have the svgs I made in Inkscape today. |
| 03:41 | < celticminstrel> | Okay, why is this off by one? |
| 03:41 | < celticminstrel> | It rotates fine (in the wrong direction, but that's okay since I needed both directions), but it also shifts down by one. |
| 03:42 | <~Vornicus> | You can also manipulate svg using js or any other xml manipulation program. |
| 03:43 | <~Vornicus> | what's your rotation matrix look like? |
| 03:43 | < celticminstrel> | I'm not using a matrix... |
| 03:43 | < celticminstrel> | I'm doing coordinate substitution, I think. |
| 03:44 | < celticminstrel> | (x,y) -> (y, w - x) |

| 03:46 | < celticminstrel> | ...I should check and make sure it's not that it's doing it exactly right and there's actually something there I didn't know about. |
| 03:46 | < celticminstrel> | ...that sentence is convoluted. |

| 03:47 | < celticminstrel> | If four rotations get me back to exactly where I started, it's probably fine. |
| 03:47 | <~Vornicus> | what's w here? |
| 03:47 | < celticminstrel> | Width. |
| 03:47 | <~Vornicus> | 0 indexed? |
| 03:47 | < celticminstrel> | Yes. |
| 03:47 | <@ToxicFrog> | Tarinaky: you misunderstand |
| 03:48 | <@ToxicFrog> | You have SVGs |
| 03:48 | <@ToxicFrog> | You want to convert them into PNGs |
| 03:48 | <~Vornicus> | w - 1 - x instead, iirc |
| 03:48 | <@ToxicFrog> | There are tools specifically designed for bulk conversion of images between formats, and they are good at it. |
| 03:48 | <@ToxicFrog> | Inkscape isn't one of them. |
| 03:49 | < celticminstrel> | Incidentally, w is actually called width in the code; I shortened it because I thought it was obvious. <_< |
| 03:52 | <@ToxicFrog> | 34231111111 |
| 03:52 | <~Vornicus> | \o/ |
| 03:54 | < celticminstrel> | I should really do something about trimming excess empty rows and columns on the right and bottom... |
| 03:56 | <~Vornicus> | like you wish to trim, or you are but shouldn't? |
| 03:57 | < celticminstrel> | The former. |
| 04:01 | < celticminstrel> | I suppose all I have to do is figure out the highest (x,y) that has something useful in it, and then tell multi_array to resize and exclude everything beyond that. |
| 04:06 | <~Vornicus> | WARNING: don't look for a high (x, y) - look for a high x and a high y |
| 04:06 | < celticminstrel> | Right. |
| 04:07 | < celticminstrel> | I'll do that after I implement transformations. My initial horizontal flip is giving odd results. I think it's completely wrong. |
| 04:08 | <~Vornicus> | oh, what language? |
| 04:08 | < celticminstrel> | Hm? |
| 04:08 | < celticminstrel> | I'm using C++. |
| 04:08 | < celticminstrel> | Why? |
| 04:08 | <~Vornicus> | ok. |
| 04:09 | <~Vornicus> | If you were in Python there's some cute tricks you can do for array rotation. It's like two function calls if I remember it right. |
| 04:09 | < celticminstrel> | Ah. |
| 04:12 | < celticminstrel> | Okay, flipping works! |
| 04:12 | < celticminstrel> | That's pretty much everything. Translation is almost trivial. |

| 07:11 | | * Vornicus wonders how vbos stack up to display lists. |
| 07:15 | | iospace is now known as iospacedout |
| 07:23 | < Rhamphoryncus> | VAO+VBO are superior to display lists, but of course the usage isn't exactly the same |
| 07:24 | < Rhamphoryncus> | a display list doesn't store raw data. Instead, it stores the commands to produce the data. In practice this still compiles down to the raw data, but limits it to static forms |
| 07:27 | < Rhamphoryncus> | Performance wise, where a display list works well, it might not be much difference from a VAO+VBO |
| 07:27 | | Derakon is now known as Derakon[AFK] |
| 07:28 | < Rhamphoryncus> | Also note that the original VBO had client side data as well (on the CPU), while the modern VAO form only has server side |

| 19:17 | <&Derakon> | If you're saying e.g. A declares virtual function, B inherits from A and implements function, and C inherits from B, then yes that should be fine. |
| 19:17 | <&Derakon> | If you're talking multiple inheritance, fuck off~ |
| 19:20 | < celticminstrel> | I'm talking multiple inheritance, but one of the subclasses is pure abstract, so it's like an interface. |
| 19:23 | < celticminstrel> | I moved the interface up a level as a quick fix, but if I can avoid doing that it'd be preferable. |
