| 00:18 | <&McMartin> | Meanwhile, in "McMartin lives some strange alternate plane of existence" news, I just debugged some graphics code by looking at the resulting transformation matrices and deciding one of them looked wrong |
| 00:19 | <~Vornicus> | I haven't gotten to that level yet |
| 00:20 | <&McMartin> | The actual bug here is that a software component outside of our control is ignoring EXIF data regarding orientation, so I have to do rotates/flips on the way to that component |
| 00:20 | <&McMartin> | So in one of those cases the constants were multiples of -1, which is Kind Of A Tell~ |
| 00:20 | <&McMartin> | *weren't multiples |
| 00:21 | <~Vornicus> | ...yes, that would be pretty obvious |
| 00:22 | <&McMartin> | But somehow this is easier than digging through the code and making sure the rotation amount is sane |
| 00:23 | <&McMartin> | I'm not 100% convinced I shouldn't just be hard-coding these eight matrices |
| 00:27 | <~Vornicus> | tropico 4 free on humble |
| 00:27 | <~Vornicus> | got like... 18 hours to claim it |
| 00:28 | <~Vornicus> | this is not #fleet |
| 00:30 | <~Vornicus> | I'd probably encode as the four 90deg rotations and the reflections, separately |
| 00:30 | <&McMartin> | Well, it's more that the rotation requires a pair of translations surrounding it |
| 00:31 | <~Vornicus> | well okay |
| 00:31 | <&McMartin> | And so does the flip |
| 00:31 | <&McMartin> | So it's "big switch statement to compute angle of rotation, whether it's flipped, and whether the source and destination rects have different dimensions" |
| 00:31 | <&McMartin> | And then it builds the transform out of translations, scales, and rotates |
| 00:32 | <&McMartin> | And one clause of the switch had a bad angle |
| 00:32 | <&McMartin> | The resulting matrix includes some translations that stick, so that 0,0 is in the correct corner, more or less |
| 00:32 | <&McMartin> | But those entries in the matrix are always the width, the height, or their negations, as well |
