From 64635f3b35a64d1f941aadaf2bdcfd114b7053cc Mon Sep 17 00:00:00 2001 From: Calixte Denizet Date: Tue, 21 May 2024 14:41:07 +0200 Subject: [PATCH] [api-minor][Editor] When switching to editing mode, redraw pages containing editable annotations Right now, editable annotations are using their own canvas when they're drawn, but it induces several issues: - if the annotation has to be composed with the page then the canvas must be correctly composed with its parent. That means we should move the canvas under canvasWrapper and we should extract composing info from the drawing instructions... Currently it's the case with highlight annotations. - we use some extra memory for those canvas even if the user will never edit them, which the case for example when opening a pdf in Fenix. So with this patch, all the editable annotations are drawn on the canvas. When the user switches to editing mode, then the pages with some editable annotations are redrawn but without them: they'll be replaced by their counterpart in the annotation editor layer. --- src/core/annotation.js | 8 +- src/core/document.js | 6 +- src/core/worker.js | 2 + src/display/annotation_layer.js | 18 +- src/display/annotation_storage.js | 39 ++++- src/display/api.js | 39 ++++- test/integration/annotation_spec.mjs | 8 + test/integration/freetext_editor_spec.mjs | 200 ++++++++++++++-------- test/integration/stamp_editor_spec.mjs | 4 +- test/integration/test_utils.mjs | 23 ++- web/annotation_layer_builder.js | 4 + web/pdf_page_view.js | 21 +++ web/pdf_viewer.js | 89 +++++++++- 13 files changed, 358 insertions(+), 103 deletions(-) diff --git a/src/core/annotation.js b/src/core/annotation.js index 4e821b987..632112d96 100644 --- a/src/core/annotation.js +++ b/src/core/annotation.js @@ -680,6 +680,7 @@ class Annotation { hasOwnCanvas: false, noRotate: !!(this.flags & AnnotationFlag.NOROTATE), noHTML: isLocked && isContentLocked, + isEditable: false, };
