| * | dithering ppm files using all 256 colors | Kartik K. Agaram | 2021-07-13 | 1 | -2/+205 |
| | | | | | | Not quite working yet, but yields an interesting 'sketching-like' effect. | ||||
| * | scaling the palette working on third attempt | Kartik K. Agaram | 2021-07-13 | 1 | -2/+16 |
| | | | | | | See commits b4e997adb8 and 2777479a94. This seems like a good sign that dithering is now extremely precise. | ||||
| * | get rid of our ugly rounding code | Kartik K. Agaram | 2021-07-13 | 1 | -8/+1 |
| | | | | | | | | | | | | | | | | It turns out "truncating" the last 4 bits is actually more accurate, because it divides up the palette evenly. Before: 0-7 -> 0 8-0x17 -> 1 0x18-0x27 -> 2 ... 0xd8-0xe7 -> 0xe 0xe8-0xff -> 0xf The first interval is just 8 shades, and the final interval is 24 shades. | ||||
| * | clean up some unseemly speckles | Kartik K. Agaram | 2021-07-13 | 1 | -3/+2 |
| | | | | | | | | Turns out they were a bug after all, and scaling the palette was just making them more obvious. The bug: I was carefully clamping to 0xf0 to avoid rounding later, but I forgot to do so for values between 0xf0 and 0xff. As a result, some values could round up past 0xff and turn black. | ||||

| * | give up on .pgm files with color depths != 255 | Kartik K. Agaram | 2021-07-13 | 1 | -9/+5 |
| | | | | | | | Things kinda seem to work for color depths close to 255, but it isn't really the goal here, and I don't have the skills of numerical analysis to track this down. | ||||
| * | undo | Kartik K. Agaram | 2021-07-13 | 1 | -19/+7 |

| * | experiment | Kartik K. Agaram | 2021-07-13 | 1 | -7/+19 |
| | | | | | | Now scaling pixels to 255 levels looks a lot better. Still worse, though. On both t.pgm and barbara.pgm. | ||||
| * | now t.pgm looks right | Kartik K. Agaram | 2021-07-13 | 1 | -7/+7 |
| | | |||||
| * | clamp the upper bound of nearest-color as well | Kartik K. Agaram | 2021-07-13 | 1 | -30/+53 |
| | | | | | | I'd kinda convinced myself it would never happen, but observations say otherwise. Unless there's a bug elsewhere.. | ||||
