From 0abcccc4aab4d893ac2a0ef116ff1f0c006fbc30 Mon Sep 17 00:00:00 2001 From: Tor Andersson Date: Fri, 6 Jul 2018 14:20:26 +0200 Subject: Rejig pdf_update_page and pdf_update_annot. The intent is for a user to iterate over the annotations on a page calling pdf_update_annot for each one. If this function returns true, then the annotation has changed since the last time it was called, and the user needs to re-render. pdf_update_page is a simple loop over the annotations on a page, for use if you only care about page level granularity. Users should no longer look at or change the pdf_annot.has_new_ap field. --- source/tools/murun.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) (limited to 'source/tools/murun.c') diff --git a/source/tools/murun.c b/source/tools/murun.c index c6ad673f..02144df4 100644 --- a/source/tools/murun.c +++ b/source/tools/murun.c @@ -4040,6 +4040,18 @@ static void ffi_PDFPage_deleteAnnotation(js_State *J) rethrow(J); } +static void ffi_PDFPage_update(js_State *J) +{ + fz_context *ctx = js_getcontext(J); + pdf_page *page = js_touserdata(J, 0, "pdf_page"); + int changed = 0; + fz_try(ctx) + changed = pdf_update_page(ctx, page); + fz_catch(ctx) + rethrow(J); + js_pushboolean(J, changed); +} + static void ffi_PDFAnnotation_getType(js_State *J) { fz_context *ctx = js_getcontext(J); @@ -4435,6 +4447,18 @@ static void ffi_PDFAnnotation_updateAppearance(js_State *J) rethrow(J); } +static void ffi_PDFAnnotation_update(js_State *J) +{ + fz_context *ctx = js_getcontext(J); + pdf_annot *annot = js_touserdata(J, 0, "pdf_annot"); + int changed = 0; + fz_try(ctx) + changed = pdf_update_annot(ctx, annot); + fz_catch(ctx) + rethrow(J); + js_pushboolean(J, changed); +} + #endif /* FZ_ENABLE_PDF */ int murun_main(int argc, char **argv) @@ -4737,6 +4761,7 @@ int murun_main(int argc, char **argv) { jsB_propfun(J, "PDFPage.createAnnotation", ffi_PDFPage_createAnnotation, 1); jsB_propfun(J, "PDFPage.deleteAnnotation", ffi_PDFPage_deleteAnnotation, 1); + jsB_propfun(J, "PDFPage.update", ffi_PDFPage_update, 0); } js_setregistry(J, "pdf_page"); @@ -4765,6 +4790,7 @@ int murun_main(int argc, char **argv) jsB_propfun(J, "PDFAnnotation.getModificationDate", ffi_PDFAnnotation_getModificationDate, 0); jsB_propfun(J, "PDFAnnotation.setModificationDate", ffi_PDFAnnotation_setModificationDate, 0); jsB_propfun(J, "PDFAnnotation.updateAppearance", ffi_PDFAnnotation_updateAppearance, 0); + jsB_propfun(J, "PDFAnnotation.update", ffi_PDFAnnotation_update, 0); } js_setregistry(J, "pdf_annot"); -- cgit v1.2.3
