Office applications

Exports end up in slides and documents more often than in browsers. Office applications cannot be driven by a test, so their checks are done by hand with a kit of files, and the results are kept here. The browsers are checked automatically: see browsers.md.

Making the kit

Section titled “Making the kit”
Terminal window
pnpm verification:kit kit

The command exports the purchase reference example into kit/ (any folder name works):

File What it is
purchase-slide.svg The executive slide (1280 × 720) with embedded fonts, linked to the kit’s URL
purchase-slide.png The same slide at twice the pixels (2560 × 1440), on a transparent background
purchase-slide.pdf The same slide as a vector page with embedded fonts and the link
purchase-story.html The animated story in the HTML player, one file that works offline
purchase-story.mp4 The story as H.264 video, 1920 × 1080 at 30 frames per second
purchase-story.webm The story as VP9 video, 1920 × 1080 at 30 frames per second
purchase-story.gif The story as an animated GIF, 960 × 540 at 15 frames per second
checklist.md The checklist below, with the date and the browser that captured the files

The videos need FFmpeg; without it the kit has the first four files and says so. The link of the SVG and the PDF is https://example.com/meltemi/purchase.

Checklist

Section titled “Checklist”

Go through each check for each file in each application, and write the result in the results table: pass, fail with what went wrong, or n/a when the application does not take the format.

  1. Insert. The file goes in by the application’s own insert command (Insert › Pictures, Insert › Video, drag and drop) without an error or a conversion prompt.
  2. Size. Inserted at 100 %, the picture keeps its proportions (16:9 for the slide and the story) and fills a 16:9 slide edge to edge when stretched to the slide’s width.
  3. Scale. Scaled up to four times, SVG and PDF stay sharp (vector); PNG stays sharp up to twice. Scaled down to a thumbnail, the text stays readable down to the size the application shows.
  4. Fonts. The title “From click to confirmed order” shows in Inter as in the export, not in a substitute font, also on a computer where Inter is not installed: SVG and PDF carry the font, PNG and the videos carry pixels.
  5. Transparency. On a coloured slide background, the PNG shows the background around the drawing; SVG and PDF draw the canvas they were exported with.
  6. Links. In the slide show (or the PDF reader), clicking the SVG or PDF picture opens the kit’s URL, where the application supports links on pictures.
  7. Playback. In the slide show, MP4 and WebM play from start to end without a black frame; the GIF animates and loops; the HTML player plays, pauses and answers the keyboard where the application can show web content (otherwise n/a).
  8. Saving. After saving, closing and opening the presentation again, every inserted file is still there, and still passes checks 2 to 7.

Results

Section titled “Results”

The owner fills in a row per application, version and format; one cell per check, in the checklist’s order. A failure points at what went wrong.

What to expect

Section titled “What to expect”

These expectations come from the formats; the table above confirms or corrects them on real versions of the applications.

  • Slide applications insert pictures and videos from files; whether a format goes in at all (SVG, PDF, WebM) depends on the application and its version, which is why each has a row.
  • Google Slides takes video only from Google Drive or YouTube: MP4 and WebM are uploaded to Drive first, and the result is recorded against that path.
  • No slide application runs the HTML player inside a slide: it is shared as a file or a link, or pasted into a page with --embed (player), so its row records opening the file from the application.
