BMP Sample File for Large Bitmap Transfer

Exercise heavy-image transfer, memory-sensitive previewing, and resizing paths with real BMP fixtures that expose uncompressed file-size costs.

Recommended Starter File

Filename bmp_2000x1200_sample_file_9.2MB.bmp
Size 9.2 MB
MIME image/bmp
SHA256 702e30333be93ece811c7f55dae73d918a9e9d27ad7cd53d5a70d8ec90e78124

Validation Checklist

  • Measure preview timing and memory-sensitive image handling on multi-megabyte BMP controls.
  • Compare small and large BMP transfers before changing upload ceilings or preview thresholds.
  • Check whether large uncompressed bitmap downloads still behave predictably on slower browser paths.
