WIA-Camera Image transfer: FName, Date...???
Posted: Wed Jan 21, 2009 3:46 pm
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
