From b5ee49d85ae054c0176248c1c4f5b84b57afcb1f Mon Sep 17 00:00:00 2001 From: wolfbeast Date: Mon, 20 Aug 2018 13:11:56 +0200 Subject: Re-implement custom background color of standalone images. This resolves #717. Note: this does not affect other applications because the platform default is to use the "darknoise" background image for standalone image, which effectively overrides a bg color. --- dom/html/ImageDocument.cpp | 17 +++++++++++++++++ 1 file changed, 17 insertions(+) (limited to 'dom/html/ImageDocument.cpp') diff --git a/dom/html/ImageDocument.cpp b/dom/html/ImageDocument.cpp index 200bb5d46d..f83a804bef 100644 --- a/dom/html/ImageDocument.cpp +++ b/dom/html/ImageDocument.cpp @@ -40,12 +40,14 @@ #include "nsThreadUtils.h" #include "nsIScrollableFrame.h" #include "nsContentUtils.h" +#include "nsCSSParser.h" // for CSS colors on the background #include "mozilla/dom/Element.h" #include "mozilla/Preferences.h" #include #define AUTOMATIC_IMAGE_RESIZING_PREF "browser.enable_automatic_image_resizing" #define CLICK_IMAGE_RESIZING_PREF "browser.enable_click_image_resizing" +#define STANDALONE_IMAGE_BACKGROUND_COLOR_PREF "browser.display.standalone_images.background_color" //XXX A hack needed for Firefox's site specific zoom. #define SITE_SPECIFIC_ZOOM "browser.zoom.siteSpecific" @@ -170,6 +172,8 @@ ImageDocument::Init() mClickResizingEnabled = Preferences::GetBool(CLICK_IMAGE_RESIZING_PREF); mShouldResize = mResizeImageByDefault; mFirstResize = true; + + mBackgroundColor = Preferences::GetString(STANDALONE_IMAGE_BACKGROUND_COLOR_PREF); return NS_OK; } @@ -682,9 +686,22 @@ ImageDocument::CreateSyntheticDocument() mImageContent->SetAttr(kNameSpaceID_None, nsGkAtoms::src, srcString, false); mImageContent->SetAttr(kNameSpaceID_None, nsGkAtoms::alt, srcString, false); + // Implement mechanism for custom background color from pref. + if (!mBackgroundColor.IsEmpty()) { + nsCSSValue color; + nsCSSParser parser; + if (parser.ParseColorString(mBackgroundColor, nullptr, 0, color)) { + nsAutoString styleAttr(NS_LITERAL_STRING("background-color: ")); + styleAttr.Append(mBackgroundColor); + body->SetAttr(kNameSpaceID_None, nsGkAtoms::style, styleAttr, false); + } + } + body->AppendChildTo(mImageContent, false); imageLoader->SetLoadingEnabled(true); + UpdateTitleAndCharset(); + return NS_OK; } -- cgit v1.2.3
