Fill modes and cropping

Select a photo and open Position in the inspector. The Size group on the right has five buttons. They resize the element against the slide, and they're where most of the craft in a carousel lives.

Next to them, on photos, is Image Fit with two options, Fit and Fill. That one governs how the picture sits inside its own element rather than inside the slide.

The two-slide span

Width 2x is the signature move, and it's what horizontal frames are for. The photograph runs across the seam, so someone swiping discovers the rest of it rather than meeting a new picture.

Use it on the frame that deserves the room. Using it on every slide undoes the effect.

Cropping

Crop in the inspector bar, on photo elements only. No separate crop sheet, no rotation slider, no handles drawn on the image.

Reframe (pinch / drag) at the top of the panel puts that photo into interactive crop mode. Double-clicking the photo does the same thing. While one element is being reframed every other element ignores input, so a brand frame sitting on top can't swallow the gesture. Press Done reframing, or click the canvas background, to come out.

Seven ratio presets sit under it:

1:1 · 4:5 · 2:3 · 3:4 · 4:3 · 16:9 · 9:16

Picking one fits the element to that aspect inside the slide and sets it to fill, so the ratio crops cleanly.

Then three sliders:

The two offset sliders snap to centre. Drag one within about eighteen units of zero and it locks to zero, so recentring a crop is one gesture rather than a fight. The handles don't snap, because there are no handles.

Center puts both offsets back to zero. Reset Crop does that and returns the zoom to 100%.

Where rotation lives

Rotation is a numeric field, not a slider. Open Position, then the numeric row, and set ROT alongside X and Y. The same row carries W and H with an aspect-ratio lock.
