There are times when you may want to load or save information so that you can edit it in another program. Or on the other hand you may wish to load a Frame that is a different size to the rest, e.g. with a copyright notice on it. This is the purpose of the Import and Export functions on the File Menu.
Import Frame is the function to use for this task. The new frame is placed in the upper left corner of an empty Frame. If the import is too large to fit it is cropped. To move the import quickly to another point use Resize/Rotate Move, setting P1 to its lower right corner and P3 to the desired position of this corner, then press Set and Use Parameters on the Points dialog. To place it accurately move it manually.
This function creates a folder and places a file in it for every Frame in the Stack, plus one for Out and one for the Picture. You can use this facility to import the whole stack and the finished Picture etc into another program that can process 'Layers' for touching up and finishing off. A file selector appears which gives you some control over the file names and final location.
These take a Depthmap in the form of a .bmp file. The Red Channel contains absolute frame numbers with zero for Empty pixels, one for the bottom frame, then rising up the Stack. The Green Channel contains values between 0 and 255. Value 1 is the bottom Frame and 255 the top; the other Frames are spread out evenly amongst the intermediate values; again zero means an Empty Pixel. The Blue Channel carries some important information in the first few locations along the top row so do not modify it.
So you can Export a Depthmap, process it, and Import it again. Remember, to get meaningful results the Stack must be in the same state at both stages. A useful pair of functions here is Save Work and Resume Work, both on the Undo menu. The sequence can then be: Export Depthmap, Save Work, leave CZ, edit Depthmap and resave, restart CZ, Resume Work, Import Depthmap. You can combine this Depthmap with the Exported Rectangles above for editing, just make sure they are the same size.
