This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
| - (NSString *)tableView:(UITableView *)tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath { | |
| return @"More"; | |
| } | |
| - (void)tableView:(UITableView *)tableView swipeAccessoryButtonPushedForRowAtIndexPath:(NSIndexPath *)indexPath { | |
| NSLog(@"I wanted to be a pretty public API, but then time ran out and they forgot me..."); | |
| // Hide the More/Delete menu. | |
| [self setEditing:NO animated:YES]; | |
| } |
