What

• Frames with more than 3 million pixels are exported scaled down to that size (sqrt(3M / pixels)). Smaller frames still export at 100%.
• Key positions are multiplied by the same scale and rounded to whole pixels, so they still land on the right spot of the image Tolgee receives.
• FrameInfo.width/height are scaled too, so one FrameScreenshot is all in image pixels.

Why

Tolgee stores a screenshot at no more than 3 million pixels, so exporting more only costs upload time and server memory. A 12,000 x 12,000 px frame is a 20 to 50 MB PNG that the server needs 576 MB to open, and a self-hosted server with a small heap answers with a 500. With this change the same frame leaves Figma as a 1,732 x 1,732 px PNG of a few hundred KB.

The server side is tolgee/tolgee-platform#4044 (bounded memory while decoding, and a 400 for absurd sizes). This change also helps against servers that don't have that fix yet.

Tests

capture.test.ts: scale and positions for a huge frame, 100% for a normal frame, and frames without a bounding box or with no area.

Summary by CodeRabbit

• Bug Fixes
  • Large screenshot exports are now scaled to stay within a 3-million-pixel area, helping prevent oversized exports. Elements’ positions and dimensions remain aligned with the scaled image.
  • Smaller exports retain their original size. Frames without usable bounds, including zero-area frames, continue to export at full scale.

Walkthrough

Screenshot capture now scales frames based on their bounding-box area, up to a 3,000,000-pixel export limit. The scale also applies to reported frame dimensions and text-node positions. Frames without a bounding box or with zero area use 100% scale.

Changes

Screenshot export scaling

Layer / File(s)	Summary
Calculate and apply export scale src/main/screenshots/capture.ts, src/main/screenshots/position.ts, src/main/screenshots/__tests__/capture.test.ts	Capture calculates a scale capped at 1 from the frame area and passes it to PNG export. Reported dimensions and text-node coordinates and dimensions use that scale and are rounded. Tests cover frames below and above the area limit, and missing or zero-area bounding boxes.

Full details: Docstring Coverage

Explanation

Docstring coverage is 50.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 3 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Rounded to the pixel, neat and fine.
Small frames keep their full-size glow.}
