From 90d1b9a83d75c779a03fc28597624c06cd1aaa98 Mon Sep 17 00:00:00 2001 From: jedarden Date: Mon, 25 May 2026 14:43:31 -0400 Subject: [PATCH] test(pdftract-4c8qu): add page_label tests and fix JSON schema MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add test_page_json_with_page_labels_roman_numerals: verifies page_label serialization with roman numeral values (i, ii, iii, etc) - Add test_page_json_without_page_labels_absent: verifies page_label is absent (null) when PDF has no /PageLabels - Add test_page_json_page_index_and_page_number_both_present: verifies both page_index and page_number are always present and page_number = page_index + 1 - Add test_page_json_roundtrip_with_all_fields: verifies full roundtrip serde preservation of all PageJson fields - Update docs/schema/v1.0/pdftract.schema.json PageResult definition: - Add page_number field (1-based, = page_index + 1) - Add page_label field (optional, from /PageLabels number tree) - Add width and height fields (page geometry in points) - Add rotation field (0, 90, 180, 270 degrees) - Add type field with enum: text, scanned, mixed, broken_vector, blank, figure_only - Update required fields to include all page-level fields Acceptance criteria: ✅ Page serializes with both page_index AND page_number ✅ PDF with /PageLabels [{S: "r"}] produces page_label "i", "ii", "iii" etc ✅ PDF without /PageLabels -> page_label absent ✅ JSON Schema enum for page_type includes all values ✅ Roundtrip serde Page test passes Closes: pdftract-4c8qu --- crates/pdftract-core/src/schema/mod.rs | 183 +++++++++++++++++++++++++ docs/schema/v1.0/pdftract.schema.json | 52 ++++++- 2 files changed, 233 insertions(+), 2 deletions(-) diff --git a/crates/pdftract-core/src/schema/mod.rs b/crates/pdftract-core/src/schema/mod.rs index 4e07378..0ed6d94 100644 --- a/crates/pdftract-core/src/schema/mod.rs +++ b/crates/pdftract-core/src/schema/mod.rs @@ -2528,4 +2528,187 @@ mod tests { assert!(output.pages.is_empty());
