+## 27. A frame is a slide drawn on the board, and it is not a container
+
+**Implemented.** Phase E5 of [export.md](export.md); the smaller calls are under E5 in
+[export-decisions.md](export-decisions.md).
+
+The automatic cut (decision 26) serves a board that was drawn without a deck in mind.
+Someone preparing a board for a deck wants to say where the slides are, and the way to
+say it on a whiteboard is to draw a rectangle. **View → Frame** adds one the size of the
+screen; it can be moved, resized, renamed, and reordered like anything else selectable,
+and Export takes it as it is: whatever sits inside a frame is that slide, frames come
+first, and the rest of the board is cut automatically.
+
+A frame is deliberately not a container. The one rule the board has about containers is
+that a stroke touching exactly one of them is linked to it, and a frame around a picture
+would break that rule for every stroke on the picture. So a frame links nothing, is
+selected only by its edge or its title tab, and moving it moves nothing inside it: it is
+a label over content, read at export time.
+
+Frames are the first object to change the file format since 1.0, and the change is kept
+as small as it can be: a board is written as version 6 only when it holds a frame, so a
+board without one still opens in every release since format 5.

+## E5 — Frames
+
+- **A frame is not a container.** It implements no container interface, so strokes never
+ link to it and it never takes part in the single-container test: a frame drawn around
+ a picture does not stop ink from linking to the picture. Deleting a frame deletes only
+ the frame.
+- **A frame is selected by its edge or its title tab, never by its inside**, so
+ everything inside it stays reachable to the pen and the mouse. The band is 8 screen
+ pixels either side of the edge and the tab 160 by 22 screen pixels at the top-left
+ corner, both divided by the zoom so they feel the same at any magnification.
+- **View → Frame** (mnemonic A) adds a frame the size of the visible board, inset by 8%
+ so its edge is under the pen and not under the window's edge, titled "Slide n", and
+ selects it. F2 on a selected frame renames it through a small dialog. There is no
+ shortcut for adding one; the command strip is reachable with Alt+V.
+- **Moving or resizing a frame moves nothing inside it.** A frame is a label over
+ content, and the export reads what it covers at export time. Resizing keeps the
+ aspect, as the resize gesture does for everything else, which for a frame created at
+ the screen's shape means it stays slide-shaped.
+- **Frames are drawn over everything on screen** as a dashed outline with a filled tab,
+ and left out of every export picture, the overview, and `preview.png`.
+- **Frames win in the partitioner.** Every unit whose center lies inside a frame belongs
+ to that frame, frames come first (creation order under Drawing order, top-left to
+ bottom-right under Reading order), the frame's own rectangle is the area, its title is
+ the slide title when it has one, and whatever is left is partitioned as before. A frame
+ is never an object of an area, so it never appears in an export.
+- **Bring to front and Send to back work on a frame**, and since drawing order sorts
+ frames by z-index, they are also how the slide order is changed.
+- **The archive version moves to 6 only for a board that holds a frame.** A board
+ without one is still written as version 5 and keeps opening in every release since
+ format 5; a board with frames asks for this release. The frame's title travels in the
+ DTO's text title field rather than a new one.
+- **A frame is not copied** by Ctrl+C: there is nothing on the clipboard a frame could be.

Drawing with a mouse
Containers
Images, LiveViews, and text blocks are containers. With a mouse, click to move, drag the circular handle to resize while keeping aspect ratio — hold Ctrl too with Mouse drawing on. Releasing the mouse returns to the drawing tool you had. Imported images accept PNG, JPEG, BMP, GIF, and SVG, including clipboard paste and Explorer drag-and-drop. An SVG is kept as its markup and redrawn at every size, so enlarging one costs it nothing.
View → Bring to front and View → Send to back reorder the selected container and its linked strokes. Strokes cannot be reordered on their own.
+
View → Frame adds a frame the size of the screen: a slide drawn on the board. A frame is selected by its dashed edge or by its title tab, never by its inside, so everything in it stays reachable; drag it to move it, drag the handle to resize it, press F2 to rename it, and Delete removes the frame alone. Moving a frame moves nothing inside it: it is a label over content. Export takes frames as they are, first and in the order they were added, and cuts the rest of the board automatically. Frames never appear in an export or in a preview.
Text, SQL, and DAX
Paste prefers an image when the clipboard has one, including a file SnagIt or another capture tool left on the clipboard. Paste plain text to create a selected text container.
