Problem

The example has made the thumbnail in one pdf -> jpg call since fd2449c. It asks for ImageHeight 300 and ImageWidth 300, but returns 300x388 for the portrait test.pdf: without FitToSize the API applies the width, keeps the aspect ratio and lets the height grow.

Change

FitToSize: true fits the image inside both limits: 231x300. The PHP, Python, Ruby, Java and .NET thumbnail examples now produce the same file.

Verification

Run from the repository root after npm ci && npm run build, Node v24.20.0, production API, 2026-11-06. $TMPDIR is the local temp folder:

$ node examples/create_pdf_thumbnail.js        # main d638dae
The thumbnail saved to
$TMPDIR/test.jpg

test.jpg: 300x388 px, 13,317 bytes.

$ node examples/create_pdf_thumbnail.js        # this branch
The thumbnail saved to
$TMPDIR/test.jpg

test.jpg: 231x300 px, 8,858 bytes.

CI runs the examples against staging, whose pdf -> jpg also has FitToSize (spec).

Only the example changes, not the library, so there is no CHANGELOG entry.

The thumbnail examples of the other SDKs are fixed in ConvertAPI/convertapi-library-python#61, ConvertAPI/convertapi-library-php#72, ConvertAPI/convertapi-library-ruby#42, ConvertAPI/convertapi-library-java#56, ConvertAPI/convertapi-library-dotnet#82.
