Using the old code I was able to pull the alpha byte out after the red, but how would that we accomplished using the more efficient version:

var pixelValue:uint = fs.readUnsignedByte() | fs.readUnsignedShort() << 8;

[...] in AS3 ? The Flash Player does it natively and supports it, its not like decoding animated GIFs, or BMP, etc. Well, for my part, I needed a JPEG decoding class for AlivePDF in order to make the [...]

[...] Built in image support of Adobe Flash Player limits you to 3 image formats: gif, jpg and png. While this has worked well for many, many years… I recently have needed to expand the types of formats that I could use in Flash Player. I should also note that you can absolutely add support for these formats directly in ActionScript using ByteArray. For example Mike Chambers blogged about an AS3 BMP parser. [...]

[...] Mike Chambers à trouvé une astuce bien sympa qui permet de charger et d’afficher des images 24Bit BMP dans le player Flash. Bon je sais, vouloir charger du BMP dans Flash, ça n’arrive pas tous les jours mais cet exemple met en évidence l’utilité de charger les données au format binaire. [...]

No computer science degree here either – appreciate your sharing that. I’ll bookmark this and review Lee’s presentation. LB is a wonderful trainer isn’t he?! My hero and role model. Liz

Sweet, thanks for sharing. I don’t have a computer science degree either, so I’m always happy to see examples of working with low-level bits and bytes and such.
