Windows 7中的放大鏡也存在Bug

Win7之家（ airtaxifl.com）：Windows 7中的放大鏡也存在Bug

 日前，來(lái)自澳大利亞網(wǎng)站Media Access Australia的Dr Scott Hollier發(fā)表文章稱(chēng)Windows 7中的放大鏡對(duì)于視力有障礙的用戶(hù)而言并不好用，很有可能是個(gè)“Bug”。

Hollier稱(chēng)此Bug出現(xiàn)在用戶(hù)在高對(duì)比度顏色方案下使用放大鏡全屏瀏覽時(shí)。似乎Windows 7中的放大鏡在很大程度上要依賴(lài)Aero圖形引擎，也就是說(shuō)只有在Aero顏色方案下才能正常工作。而當(dāng)用戶(hù)切換到高對(duì)比度顏色方案，比如High Contrast Black時(shí)，放大鏡就變成了舊版的樣子。

而據(jù)Hollier所說(shuō)，大多數(shù)視力障礙用戶(hù)在使用全屏放大鏡時(shí)都必須配合高對(duì)比度顏色方案，這對(duì)于成千上萬(wàn)名弱視用戶(hù)而言，不得不說(shuō)是個(gè)重大的bug。他們已經(jīng)向微軟發(fā)送了bug報(bào)告，等到微軟發(fā)言人給出答復(fù)。

附部分原文：

Dan Warne has tipped us off about a "bug" in Windows 7 for vision impaired people.Dr Scott Hollier of Media Access Australia wrote to APC mag to reveal the problem.

Hollier says "The bug occurs when a user tries to use the full screen Magnifier in combination with a high contrast colour scheme. The Magnifier appears to be largely dependent on the Aero graphics engine, meaning that it works well when Aero colour themes are used. However, when a user switches to a high contrast colour scheme such as High Contrast Black, the OS dumps the user back into the old Magnifier feature which, by default, shows a small magnification bar at the top of the screen."
