B4A Library JpegUtils library gives access to Exif data

This library contains an ExifData object that allows you to read and write the EXIF data in a Jpeg file. It is a very thin wrapper over the Android ExifInterface class.

No. It can only work with files.

Oh!

Initialize takes a file and DecodeThumbnail takes Byte array. Why is it so?

Only @agraham can answer this question.

Hi @agraham - in doing some testing with an existing app running on an Android N device, I'm finding that calling the .Initialize method is causing the following error:

java.io.FileNotFoundException: AssetsDir/pet2.png (No such file or directory)

It doesn't happen on previous versions of Android & it doesn't happen if I just initialize & display a bitmap without trying to use your library. Looking at the Android Developer documentation for ExifInterface, I notice there have been some changes for Android N so I'm wondering if maybe they have changed something in the constructor you use in the library?


UPDATE: I don't think it's an issue with the constructor because if I copy the file to Files.DirInternal, then call the exif functions it works fine. It seems to be something that the library (or the API) doesn't like about the Files.DirAssets directory all of a sudden.

Thanks - Colin.

Is there a TAG/is it possible to get the number of colors (es: 16M) of the Jpeg file ?

In case the same thing happens to someone, when unzip use "extract all" instead of "extract here".

Thank you, but i need the value in grades ( fox example 38,5448521455895), how i can convert it? another question whit exif i tried to set the lat lon coordinates in a pic, but it don't works


whitout a clear example is very hard for me to undestand, cause i'm not a expert thenk you

Did you ever get it sorted, or gave up? (Now I realise why I so often see positions in EXIF botched up!)
