PDF XFA: Barcode rendering is very slow |
||||||
Issue descriptionTo repro, on an XFA-enabled build where crbug.com/872903 is fixed: 1. Open the attached imm5257e_debug_add_page.qpdf. 2. Press the Validate button. Expected: Scrolling through the beautiful barcodes in the newly added page 6 is smooth. Actual: Scrolling is not smooth, rendering is slow.

It's good enough that you don't notice the slow scrolling anymore.
