Declaration: ReadTIFFArray (FName: string; var Data: TInt2DArray; BitMask: longword; FeedBack: boolean): integer;;
Reads the photo data stored in TIFF format and copies it into the dyamic array Data. The photo may be either a black&white, grayscale, or RGB color image. The parameter FName specifies the full file path of the TIFF file. The parameter BitMask allows to mask off bits of the image. For example, setting Bitmask to $0000FF00 extracts only the green values.

The parameter Feedback controls whether a visual feedback is provided during the import of the data. Please note that unless the script progress bar is already visible you have to make it visible before calling ReadTIFFArray, otherwise the feedback will not be displayed. You can activate the script progress bar by calling the function ScriptBar(0).

The function returns the following error codes:

 0 ... everything is OK, the TIFF file has been imported
-1 ... the file does not exist
