ios 長(zhǎng)按 放大鏡

If you’ve ever found yourself wishing you had?a magnifying glass with you, iOS 10 can now serve as an excellent replacement. The new Magnifier–not to be confused with the Text Size and Zoom features that makes your on-screen text bigger–uses your phone’s camera and flashlight to make sure you can always read that receipt or dig out that splinter.

如果您曾經(jīng)希望自己帶一個(gè)放大鏡，現(xiàn)在可以將iOS 10用作替代品。 新的放大鏡(不要與使您的屏幕上的文本變大的文本大小和縮放功能混淆)使用手機(jī)的攝像頭和手電筒，以確保您始終可以讀取收據(jù)或挖出碎片。

如何啟用放大鏡 (How to Enable the Magnifier)

Before using the Magnifier, you’ll have to enable it. In Settings, tap “General.”

在使用放大鏡之前，您必須先啟用它。 在“設(shè)置”中，點(diǎn)擊“常規(guī)”。

On the General settings screen, tap “Accessibility.”

在常規(guī)設(shè)置屏幕上，點(diǎn)擊“輔助功能”。

On the Accessibility screen, tap the “Magnifier” setting.

在“輔助功能”屏幕上，點(diǎn)擊“放大鏡”設(shè)置。

Turn on the “Magnifier” option. And if you want iOS to automatically set the default brightness and contrast when you open the Magnifier, go ahead and turn on the “Auto-Brightness” setting. You can always adjust them yourself when you’re using Magnifier, regardless of whether “Auto-Brightness” is turned on.

打開“放大鏡”選項(xiàng)。 而且，如果您希望iOS在打開放大鏡時(shí)自動(dòng)設(shè)置默認(rèn)的亮度和對(duì)比度，請(qǐng)繼續(xù)并打開“自動(dòng)亮度”設(shè)置。 使用放大鏡時(shí)，無論是否打開“自動(dòng)亮度”，都可以自己進(jìn)行調(diào)整。

And now that you’ve got Magnifier enabled, it’s time to put it to use.

現(xiàn)在您已啟用放大鏡，是時(shí)候使用它了。

如何使用放大鏡 (How to Use the Magnifier)

To start the Magnifier, triple-click your Home button. If Magnifier is the only accessibility option you have enabled to use triple-click, Magnifier will open immediately. If you have more than one setting assigned to use triple-click, you’ll see a pop up menu with your options. Just tap “Magnifier.”

要啟動(dòng)放大鏡，請(qǐng)三按“主頁”按鈕。 如果放大鏡是您已啟用使用三次單擊的唯一輔助功能選項(xiàng)，則放大鏡將立即打開。 如果您分配了多個(gè)設(shè)置來使用三次單擊，則將看到一個(gè)包含選項(xiàng)的彈出菜單。 只需點(diǎn)擊“放大鏡”。

The Magnifier opens to its lowest level zoom, which is pretty much no zoom at all. Below on the left, you can see the default zoom on some 4-point type. Slide the “Zoom” slider, though, and all is revealed.

放大鏡打開到最低級(jí)別的縮放，幾乎完全沒有縮放。 在左下方，您可以看到某些4點(diǎn)類型的默認(rèn)縮放比例。 但是，滑動(dòng)“縮放”滑塊，所有內(nèi)容都會(huì)顯示出來。

If you’re in a dark room–say, trying to read a receipt in a dimly-lit restaurant–you can turn on your flashlight to illuminate things by hitting the “Flashlight” button with the lightning bolt. And don’t worry, it uses a lower setting than the blinding default used by the normal flashlight (which, by the way, you can now change). If you’re having trouble with the focus going in and out at higher zoom levels, tap the “Lock” button to lock the focus and stabilize things a bit.

如果您在黑暗的房間里(例如，嘗試在光線昏暗的餐廳中閱讀收據(jù))，則可以用閃電擊中“手電筒”按鈕來打開手電筒以照亮事物。 不用擔(dān)心，它使用的設(shè)置比普通手電筒使用的默認(rèn)值低(順便說一下， 您現(xiàn)在可以更改 )。 如果您在以較高的縮放級(jí)別來回移動(dòng)焦點(diǎn)時(shí)遇到麻煩，請(qǐng)點(diǎn)按“鎖定”按鈕以鎖定焦點(diǎn)并稍微穩(wěn)定一下。

Perhaps one of the best features of the Magnifier is the ability to freeze the frame and then look at it without having to hold your hand in place over what you’re looking at. Tap the big “Freeze Frame” button at the bottom center.

放大鏡的最佳功能之一就是可以凍結(jié)框架然后看著它，而無需將手放在待查看內(nèi)容上。 點(diǎn)擊底部中心的大“凍結(jié)框架”按鈕。

Whatever you were looking at is captured and displayed full screen. You can move the screen around by dragging it and adjust the?zoom level however you want. When you want return to the Magnifier, just tap the screen. Note that this doesn’t actually save?a picture of what you’re looking at, but you can always take a screenshot of your captured image by pressing your Home and Power buttons at the same time.

無論您在看什么，都將捕獲并全屏顯示。 您可以通過拖動(dòng)屏幕來移動(dòng)屏幕，并根據(jù)需要調(diào)整縮放級(jí)別。 當(dāng)您想返回放大鏡時(shí)，只需點(diǎn)擊屏幕。 請(qǐng)注意，這實(shí)際上并不會(huì)保存您正在查看的圖片，但是您始終可以通過同時(shí)按下“主頁”和“電源”按鈕來拍攝捕獲圖像的屏幕截圖 。

Back on the main Magnifier screen, you also?have a set of filters you?can play with that might make what you’re looking at a little more visible. Just tap the “Filters” button.

回到“放大鏡”主屏幕，您還可以使用一組過濾器，這些過濾器可以使您所看到的內(nèi)容更加清晰可見。 只需點(diǎn)擊“過濾器”按鈕。

At the top of the controls, you can slide left and right to select different color filters like “Yellow/Blue,” “Grayscale,” “Red/Black,” and more. You can also tap the “Invert Filters” button to invert the colors of whatever filter you have applied or just invert the normal colors if you have no filter applied. You can also use this screen to change brightness and contrast levels.

在控件的頂部，您可以左右滑動(dòng)以選擇不同的濾色器，例如“黃色/藍(lán)色”，“灰度”，“紅色/黑色”等等。 您也可以點(diǎn)擊“反轉(zhuǎn)濾鏡”按鈕來反轉(zhuǎn)已應(yīng)用的任何濾鏡的顏色，或者如果您未應(yīng)用濾鏡，則僅反轉(zhuǎn)正常的顏色。 您也可以使用此屏幕更改亮度和對(duì)比度。

The filter you choose will stay applied until you turn it off by disabling the Invert Filters switch and sliding the filter setting back to none. This means that once you set a filter, you can return to the main Magnifier screen by tapping the “Filters” button again. There, you can adjust zoom levels or take a freeze frame while your filter is still applied.

您選擇的濾鏡將保持應(yīng)用狀態(tài)，直到您通過禁用“反轉(zhuǎn)濾鏡”開關(guān)并將濾鏡設(shè)置滑回?zé)o而將其關(guān)閉。 這意味著，一旦設(shè)置了濾鏡，就可以再次點(diǎn)擊“濾鏡”按鈕返回到放大鏡主屏幕。 在那里，您可以在仍應(yīng)用濾鏡的同時(shí)調(diào)整縮放級(jí)別或拍攝定格畫面。

All in all, Magnifier is a pretty handy addition for anyone, even if you don’t have?difficulty reading fine print.

總而言之，即使您沒有閱讀精美印刷品的麻煩，放大鏡對(duì)任何人來說都是非常方便的補(bǔ)充。
