Use a six-page neutral slide fixture where every visible page is 540 by 720 PDF points and each page displays its source number. Enter 1-3,5, choose JPEG, 96 PPI and quality 0.85. This fixture demonstrates selection rather than reordering: the parser expands the range and keeps the ascending source sequence.
Expected pages and dimensions
The selected source pages are exactly 1, 2, 3 and 5. Page 4 is omitted and page 6 is not implied. At 96 PPI, each 540 by 720 point viewport becomes 720 by 960 pixels, for 691,200 pixels per page and 2,764,800 total. The JPEG quality affects encoding, not these dimensions. Inputs such as 3-1, 1,1, 0, 1,,3 or 7 must fail before rendering rather than being repaired or partially accepted.
Expected source-order ZIP
Every result must begin with the JPEG start marker and decode to 720 by 960 pixels. The archive source-pages.zip contains source-page-001.jpg, source-page-002.jpg, source-page-003.jpg and source-page-005.jpg in that exact order. It contains no entry numbered 004 and does not renumber page 5 as output 4. Compare the visible page numbers and compression artifacts after download; the file names prove source identity but not visual correctness.
Verify the downloaded pixels
Open every downloaded PNG or JPEG in the application that will use it, confirm the page number and measured width and height, and compare visible text, fonts, colours, transparency and annotations with the authoritative PDF. Keep the PDF as the source. Raster output is a browser-rendered snapshot, not proof of vector, print, archival, accessibility, legal or semantic equivalence.
