pptxgenjs-plus-std

Layout, text-measure, table-paging, and diagram helpers for pptxgenjs-plus. These helpers compose the public addChart / addTable / position APIs — they do not replace the core library.

import pptxgen from 'pptxgenjs-plus'
import { grid, waterfall, measureText, paginateTable, cm } from 'pptxgenjs-plus-std'

const pptx = new pptxgen()
const slide = pptx.addSlide()
const at = grid()

slide.addText('Q3 bridge', { ...at(0, 0, 12, 1), fontSize: 28 })
waterfall(slide, {
  labels: ['Open', 'Sales', 'Churn'],
  values: [100, 30, -12],
  total: 'Close',
}, { ...at(0, 1, 12, 5), showValue: true })

Helpers

• grid() / gridFor(pres) — place objects on a column/row grid; throws instead of drifting off-slide
• row(area, slots) / column(area, slots) — split any { x, y, w, h } by count or weights
• cm() / pt() — centimetres and points as the inches every addX option takes
• measureText / fitText / checkOverflow / registerFontMetrics — wrap and size text from canvas, bundled Calibri (Carlito) widths, or a flat estimate
• paginateTable / tableFromHtml — page tables by measured cell height (an additional pager alongside core autoPage / tableToSlides)
• waterfall(slide, props, options?) — stacked-bar waterfall (transparent riser + signed per-point labels)

pptxgenjs-plus is a peer dependency at the same version as this package, so helpers act on the caller's own presentation instance.
