You should offer the source for DL (just the necessary .as files). It’s unnecessarily confusing to package it with all that other stuff in a .app file.

-Also, Thanks for the Class!

The source is bundled with the AIR app, download it and then right click for the source.

very cool! I don’t see a link to the source code?

Thank you for your library. I am using it in an Air ‘Photo Viewer’ application and it has helped me a lot.

Changes I have made are :

Mainly streamlining so the class does not do work that I do not need. For eg. load the thumbnail. I only need MODEL and DATETIMEORIGINAL.

Changed

stored[currentTag] = {};

stored[currentTag] = processing;

so I can do

__exif.getTagValue( Exif.MODEL ).value

I discarded creating Naming as this prevented many object that were clogging up memory like HashItem.

rawData is also exposed in a public getter so I can use this to create my own thumb for the application. No need to load the binary again as Exif has it.

This process happens over a few methods so I created some of my own properties so that Exif can carry them for me through this.

Finally I created a dispose() method to clean up as many things as possible from memory.

Thanks again.

HI! I am also interested in the above topics of writing EXIF data. I don’t need support to write all tags although some do but even a test of writing 1 tag would be helpful to learn. Thank you so much!

Giorgio you’re a god! Thank you very much for this library, it made my life so easier! I had to add a method because I wanted to work with an already loaded image, so I implemented a “parseFromRawData(ba:ByteArray):void” which initializes “_dataloaded” and “rawData” and invokes “initParsing”. It worked like a charm, but as I’m a newbie on AS3 I’m not sure if that’s the right way to do it. By the way, can it read GPS data yet? I couldn’t find any pictures with GPS data to test it with, but I would like to.

Thanks again for your great work

Hi,

I’m glad you like it, I’m in the process to go deeper on the topic you mentioned…

Hi!

Thanks for a great app. Have you seen any JPEG encoders in ActionScript that writes Exif data? The built-in encoder writes JPEGs using the JFIF format, not the Exif format.

Hi there,

thanks for your great sharing, when will you add the gps support?
im tried to did it on my own, here is what i get:

GPS TAG FOUND

current tag: 0×0 (0) type: 1 currentCount: 4 *** 514 ***

current tag: 0×0 (0) type: 1 currentCount: 131074 *** 0 ***

current tag: 0×4e (78) type: 0 currentCount: 327682 *** undefined ***

current tag: 0×3 (3) type: 0 currentCount: 6056 *** undefined ***

current tag: 0×3 (3) type: 2 currentCount: 2 *** E

current tag: 0×0 (0) type: 4 currentCount: 196613 *** 398458880 ***

the “E” is fine but how do i get the other values?

thanks a lot
