The renderer lays every slide background over white (as PowerPoint does),
so a PNG export was always opaque. A new transparentBackground option leaves
the slide background out (both the white underlay and the background fill),
so only what is on the slide is drawn over transparency. Shapes filled with
the background (useBgFill) still show it.
- render: RenderOpts::transparent_background
- engine: file.export {transparentBackground} (PNG only; other formats
refuse it and write nothing), file.render {transparentBackground}
- UI: Transparent background checkbox in the Export dialog (PNG) and in
File > Export > Change File Type > PNG; the web download honours it
- CLI: render --transparent
Dragging the Interface size slider set the interface scale on every
frame, which grew or shrank the slider under the pointer and ran it to
one of its ends. Keep the value pending in the dialog while the pointer
holds the slider and apply it on release; keyboard changes still apply
at once.
A picture was decoded at the size of its box on screen. A cropped picture
shows only part of the image, magnified, so it was decoded at a fraction of
the resolution it needs and stretched back up: Merge Shapes > Intersect,
which crops the picture to the new smaller box, left it visibly blurred.
Size the decode from the rectangle the whole image occupies instead.
The Preferences dialog applies its controls as they change (appearance,
interface size, the editing checkboxes, the comment author), and its Cancel
result was discarded, so Cancel did nothing and the window stayed open.
The dialog now remembers the settings it opened with. Cancel, Esc and the
window's close button put them back and close it; Done keeps the changes.
slide.new put the body into the first non-title placeholder in shape order,
so a layout with a small body placeholder ahead of its content placeholder
(as Keynote exports "Title & Bullets") got the body in the small box and
left the content placeholder empty.
The body now goes to the main content placeholder: idx 1 first, then a
full-size placeholder over a half/quarter one, then a text placeholder over
a picture/chart/table one, keeping shape order on ties.
Fixes#725
convert, run --save and run --export picked the format from the output
extension and fell back to native .deckcraft bytes for any extension
they didn't know, so out.odp, out.gif, out.svg and out.outline were
zips with exit status 0. They now fail before writing anything, with
the extension and the supported ones in the error.
