Are you pulling out your hair wondering why Flex 3 doesn’t auto complete BitmapData? Adobe Updater may be the answer.

Flash CS4 10.0.2

One of my co-workers called me over to troubleshoot when a folder full of FLAs were crashing Flash CS4 every time he tried to open them. He had already tried a fresh install of the software and had all of the necessary fonts. So why did it crash? Well it turns out that Flash CS4 had a bug where it would crash when embedded fonts are used.

“FLA crash on open when fonts loaded.” -Glavan on Flash (detailed list of what was fixed)

After running Adobe Updater everything worked great!

Flex Builder 3.0.2

How about Flex Builder? I recently installed Windows 7 with a fresh copy of Flex Builder 3 Professional. Unfortunately I pulled the install from one of my external hard drives and it was version 3.0.1 rather than 3.0.2. A major bug with version 3.0.1 using SDK 3.3 and higher is that BitmapData does not auto complete. After trying multiple versions of the SDK I finally found the bug report on Adobe Bugs citing that the problem was fixed in version 3.0.2.

After running Adobe Updater everything worked great!

See the common theme here? I tend to disable most of the automatic software updates since they are usually very annoying. After my experiences over the past week I will be checking Adobe Updater much more frequently! Always update after a fresh install.

Great for storing images in XML, Databases, or transmitting them over a network. This post will cover Bitmap Encoding, PNG Encoding and JPG Encoding along with the pros and cons for each.

Bitmap Encoding - (link)

PLAIN TEXT
Actionscript:
  1. // Encode
  2. var encoded:String = BitmapEncoder.encodeBase64(bitmap.bitmapData);
  3.    
  4. // Decode
  5. var bd:BitmapData = BitmapEncoder.decodeBase64(encoded);

Advantages:
Keep transparency
Fastest Method
Does not require a Loader

Disadvantages:
Largest Filesize
Will only work with images up to a certain size

PNG Encoding - (link)

PLAIN TEXT
Actionscript:
  1. // Encode   
  2. var ba:ByteArray = PNGEncoder.encode(bitmap.bitmapData);
  3. var encoded:String = Base64.encodeByteArray(ba);
  4.  
  5. // Decode   
  6. var decoded:ByteArray = Base64.decodeToByteArray(encoded);
  7. var loader:Loader = new Loader();
  8. loader.loadBytes(decoded);

Advantages:
Keep transparency
Smaller filesize than Bitmap Encoding

Disadvantages:
Slower than Bitmap Encoding
Larger than JPG Encoding
Requires Loader

JPG Encoding - (link)

PLAIN TEXT
Actionscript:
  1. // Encode
  2. var jpgEncoder:JPGEncoder = new JPGEncoder();
  3. var ba:ByteArray = jpgEncoder.encode(bitmap.bitmapData);
  4. var encoded:String = Base64.encodeByteArray(ba);
  5.  
  6. // Decode
  7. var decoded:ByteArray = Base64.decodeToByteArray(encoded);
  8. var loader:Loader = new Loader();
  9. loader.loadBytes(decoded);

Advantages:
Smallest Filesize
Variable Quality

Disadvantages:
Slower than Bitmap Encoding
No Transparency
Requires Loader
