WIA-Camera Image transfer: FName, Date...???


WIA-Camera Image transfer: FName, Date...???

Post by TommiG »

Dear colleagues,

I can connect a fotocamera (e.g. Canon Ixus) and it shows up in the twainsources as "WIA Canon...". Therefore it is easy to transfer its images into my application. Thank you for this.

But what I searching for is how to get additional informations about the images stored on the camera e.g. orig filename, date of picture taken, ...
How can I get these?
I hoped I can read VSTwain1.ExtendedImageInfoCollection, but it's size is 0.
Are these informations embeded in the image itself? Do I have to read EXIF?

Thank you in advance,
sincerly,
Thomas Gessl

Hello Thomas,

Information about picture fename, date of picture take, etc are stored in camera's local storage. Our library does not allow to work with local storage (File System) of devices but we plan to add this capability in the future.

Best regards, Alexander

Dear Alexander,

thank you for your fast answer.
However it's not exactly what I liked to hear. :)

Best regards and have a nice day,
Thomas
