From d8bdc029ecf9fcb24725305480966147b034975b Mon Sep 17 00:00:00 2001 From: Fangxun Zhao Date: Thu, 25 Jun 2026 21:57:58 +0800 Subject: [PATCH] fix(clipboard): fix jagged image under fractional scaling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Include QGuiApplication header for qGuiApp global pointer 2. Reduce border width from 4.0 to 3.0 for cleaner appearance 3. Use qGuiApp->devicePixelRatio() to get screen DPR instead of pixmap's potentially inaccurate devicePixelRatioF() Log: Fix jagged edges in clipboard images at non-100% display scale ratios fix(clipboard): 修复缩放比下剪贴板图片锯齿问题 1. 添加 QGuiApplication 头文件以使用 qGuiApp 全局指针 2. 将边框宽度从 4.0 调整为 3.0，改善视觉效果 3. 使用 qGuiApp->devicePixelRatio() 获取屏幕 DPR，替代 pixmap 自身可能不准确的 devicePixelRatioF() Log: 修复非 100% 缩放比下剪贴板图片锯齿明显的问题 PMS: BUG-315075 --- dde-clipboard/constants.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/dde-clipboard/constants.h b/dde-clipboard/constants.h index f1a6874b..c712414f 100644 --- a/dde-clipboard/constants.h +++ b/dde-clipboard/constants.h @@ -5,6 +5,7 @@ #ifndef CONSTANTS_H #define CONSTANTS_H +#include #include #include #include @@ -106,9 +107,9 @@ inline QPixmap GetRoundPixmap(const QPixmap &pix, QColor borderColor) } const int radius = 10; - const qreal borderWidth = 4.0; + const qreal borderWidth = 3.0; - const qreal dpr = pix.devicePixelRatioF(); + const qreal dpr = qGuiApp ? qGuiApp->devicePixelRatio() : pix.devicePixelRatioF(); const QSize logicalSize = pix.size(); QImage target(logicalSize * dpr, QImage::Format_ARGB32_Premultiplied);
