…faults Previously colWidth and rowHeight assumed a simplistic scaling factor, causing incorrect image and object positioning when custom widths/heights were set. This update uses accurate scaling: - 8.43 width = 640000 EMUs - 15 height = 180000 EMUs Improves placement precision for images and anchored objects.

Previously colWidth and rowHeight assumed a simplistic scaling factor, causing incorrect image and object positioning when custom widths/heights were set.
This update uses accurate scaling:
This pull request includes several changes aimed at improving code readability and accuracy in calculations, as well as adding a new test for image positioning with custom column widths. The most important changes include refactoring calculation logic in the
Anchorclass, simplifying test assertions, and introducing a new integration test for image positioning.Codebase Improvements
Refactored calculation logic in
Anchorclass: Updated column width and row height calculations to use more precise scaling factors for better accuracy. (lib/doc/anchor.js: [1] [2] [3]Simplified test assertions: Replaced multiline assertions with single-line equivalents for better readability in the test suite. (
spec/integration/workbook-xlsx-reader.spec.js: [1] [2] [3]Testing Enhancements
New integration test for image positioning: Added a test to verify that images are positioned correctly when custom column widths are set. (
spec/integration/workbook/images.spec.js: spec/integration/workbook/images.spec.jsR292-R338)Updated unit tests for
Anchorclass: Adjusted tests to reflect the new scaling factors in column width and row height calculations. (spec/unit/doc/anchor.spec.js: [1] [2] [3]These changes collectively improve the maintainability and accuracy of the codebase while enhancing test coverage.
Improves placement precision for images and anchored objects.
