    Photoshop Image Resource Metadata Structure
    In This Topic

    Adobe Photoshop files can contain data which is placed in additional resources blocks. These resources are used to store non-pixel data associated with images. ImageGear reads this data into the metadata blocks which is attached to ImGearDocument and ImGearPage.

    PhotoshopResources Level

    This level can contain arbitrary number of PhotoshopImageResource subtrees:

    Name Id Type Value Type Value Value Length Ignored on save
    PhotoshopImageResource <Res. Id> Tree N/A N/A N/A N/A
    Or in case the data is parsed
