Use a two-page fixture whose visible page boxes are 612 by 792 PDF points. Page one is portrait; page two declares a 90-degree rotation, so its visible viewport is landscape. Select all, choose PNG and 150 PPI. PageRaster must show the complete plan before it allocates the output images.
Expected plan
The scale is 150 divided by 72. Page one plans 1275 by 1650 pixels, and rotated page two plans 1650 by 1275 pixels. Each page contains 2,103,750 pixels; together they use 4,207,500 planned pixels, safely below the per-page and total limits. The order remains page 1 then page 2. Rotation changes orientation but never reorders pages or invents a new physical size claim.
Expected verified archive
After sequential rendering, both outputs must begin with the PNG signature and decode to their respective planned dimensions. The multi-page action downloads one uncompressed deterministic ZIP named source-pages.zip with source-page-001.png followed by source-page-002.png. Open both entries and compare the visible heading, vector shape, translucent element and orientation with the fixture PDF. Cancel or any verification error must expose no partial archive.
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.
