Remarks

Call this global function and pass an image list or container as the AImage parameter to retrieve the source DPI for the stored image. The dxGetImageSourceDPI function returns the dxDefaultDPI global constant value if the specified image list or container does not support the IdxSourceDPI interface.

The dxGetImageSize global function variants call the dxGetImageSourceDPI function internally to take the source DPI into account in the stored image’s on-screen size calculations.
