# A small script to change the color of mono-colored transparent .pngs
#
# Uses ImageMagick to read the most common 100% alpha color and then computes
# scale factors to multiply the whole image by. 
#
# Improvements to be made:
#   -deal with images containing pure black.
#   -make portable between new and old ImageMagick versions

A Better Build Date

Showing a build date in an app is pretty easy using __DATE__ and __TIME__ but the format is fixed. This script allows you to control the date and time format and pull the build date from the Info.plist using the CMDBundleBuildTime key.

Generate the list yourself:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS*.sdk/System/Library/Frameworks/UIKit.framework/Headers
$ grep UI_APPEARANCE_SELECTOR ./*     | \
  sed 's/NS_AVAILABLE_IOS(.*)//g'     | \
  sed 's/NS_DEPRECATED_IOS(.*)//g'    | \
  sed 's/API_AVAILABLE(.*)//g'        | \
  sed 's/API_UNAVAILABLE(.*)//g'      | \
 sed 's/UI_APPEARANCE_SELECTOR//g' | \

Step 1: Configure the table view.

• Set a view as the table footer
• Set the background color to clear.

Step 2: Set the default table view values when your view loads. The values and variables seen here are explained below.

- (void)viewDidLoad {
    [super viewDidLoad];

Description

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"
