Windows通过原生方式截图指定窗口,截图之截取整个网页

在Windows 第10中学截取截图的6种艺术 简单介绍

 

截图对于分裂的指标很要紧。它能够用来捕获台式机Computer上的别样内容的截图。所以,要是你利用Windows
10,你恐怕不清楚怎么着截图,因为它是相比较新的。因此,大家来得了5种方法,您可以屏蔽任夏雯西,特别是若是您使用Windows
10.这里有6种艺术在Windows 第10中学截取截图。

 

截图工具

Snipping工具是Windows的嵌入截图工具。每一个Windows操作台式机计算机都配有此选项。在Windows
10中搜索剪贴工具并不困难。只需在探究面板中搜索剪贴工具就可以。选择Snipping
Tool应用程序。当Snipping工具展开时,单击新建以捕获新的显示屏截图。

 

Windows + Shift + S

应用Windows + Shift + S捕获显示屏的二个区域并将其复制到剪贴板。按下Windows

  • Shift +
    S后,显示器变暗,并展现一个光标,您能够在荧屏上绘制要在荧屏截图中抓获的区域。绘制要捕获的区域并释放鼠标光标。

 

打印显示屏

点击键盘上的Prtsc开关。按按键捕获整个显示屏。以后开辟贰个图像编辑器,如Paint。按Ctrl

  • V粘贴内容。裁剪后保存图像。

 

Windows键+打字与印刷显示器

此选项捕获您的显示屏截图并活动保存。要捕获整个显示器并自行保存显示器截图,请点击Windows
Key +
PrtScn。显示屏会暗淡一分钟,让您知道荧屏截图已被破获。今后找到保存的快速照相在以下职务图片>
Screenshots文件夹。

 

Windows键+ H

假如要捕获整个显示屏举行分享,能够接纳Windows Key +
H键盘快捷方式。那将捕获整个荧屏。

 

Alt +打印荧屏

要快快切换活动窗口,请使用键盘急速键Alt +
PrtScn。那将捕捉您当前运动的窗口,并将截图复制到剪贴板。您将索要在图像编辑器中张开镜头以保

MFC通过系统API将钦定窗口导出为图片,方法之一:

来点简单共享,今儿晌午本身突然想截取浏览器里面展开的网页,是整一个网页,咋做额?有二种减轻方案

在Android的运用中,一时候大家想单独显示一部分图像,那时候将须要图形截图。

BOOL COutputManager::OutputFromWND(IN HWND hWnd, IN RECT rect)

  • Firefox【推荐、高清】
  • gnome-web-photo

1、随便截取图像的法子,以下大家切实介绍一下android中的重要类——Bitmap

{


public final class

HDC  hDC = ::GetDC(hWnd); //获取显示屏DC

使用Firefox截图

首先步:打开Firefox进入调节台

shift+F2 

第二部:能够张开截图了

  • 截取当前整个网页并下载保存

screenshot fileName --fullpage 
  • 延期截图

screenshot fileName --delay seconds --fullpage  
  • 截图仅复制到剪切板

screenshot --clipboard --fullpage 

Bitmap

extends Object
implements Parcelable

java.lang.Object

 

android.graphics.Bitmap

以下是Bitmap的百分百使用措施,大家要驾驭记住:

国有方法

overwriting the bitmap’s pixels.

void

of the given Canvas.

int

getScaledWidth)(DisplayMetrics metrics)

Convenience for calling getScaledWidth(int) with the target density of
the given DisplayMetrics.

int

getScaledWidth)(int
targetDensity)

Convenience method that returns the width of this bitmap divided by the
density scale factor.

int

Returns true if this bitmap has been recycled.

void

prepareToDraw)()

it.

void

void

writeToParcel)(Parcel p,
int flags)

Write the bitmap and its pixels to the parcel.

那是大家落到实处截图图形的要害格局:

static Bitmap createBitmap(Bitmap source, int x, int y, int width, int height)

Returns an immutable bitmap from the specified subset of the source bitmap.

第贰个參数source正是本来的Bitmap对象,前边的几个參数分别代表截取的界定。

2、另一种办法,不是不管三七二十一截取图形。而是从图像的一端(上、下、左、右)截取图像。也能够选择图像截取财富,那样的财富供给在res/drawable文件夹中国建工业总会公司立一个xml文件

<clip xmlns:android="http://schemas.android.com/apk/res/android"
    android:clipOrientation="horizontal"
    android:drawable="@drawable/ic_launcher"
    android:gravity="left" >
</clip>

下一场我们能够透过ClipDrawable获取要截取的图像:

public class

HDC  hDCMem = ::CreateCompatibleDC(hDC); //创制兼容DC

gnome-web-photo截图

gnome-web-photo是命令行截图工具,那就得先安装喽。

  • 在debian/ubuntu下安装

➜  ~ sudo apt-get install gnome-web-photo -y
  • 在yum包管理发行版安装

➜  ~ sudo yum install gnome-web-photo -y
  • 先河截图了

gnome-web-photo -t 0 --mode=photo URL fileName.png 

小心:U逍客L为你要截取网页的链接。

借使使用桌面LinuxPC呢,推荐应用Firefox,Firefox截图非常高清,轻易的共享!

ClipDrawable

extends Drawable
implements Drawable.Callback

java.lang.Object

   

android.graphics.drawable.Drawable

 

   

android.graphics.drawable.ClipDrawable

国有方法

void

draw)(Canvas canvas)

Draw in its bounds (set via setBounds) respecting optional effects such
as alpha (set via setAlpha) and color filter (set via setColorFilter).

int

getChangingConfigurations)()

Return a mask of the configuration parameters for which this drawable
may change, requiring that it be re-created.

Drawable.ConstantState

getConstantState)()

int

getIntrinsicHeight)()

Return the intrinsic height of the underlying drawable object.

int

getIntrinsicWidth)()

Return the intrinsic width of the underlying drawable object.

int

getOpacity)()

Return the opacity/transparency of this Drawable.

boolean

getPadding)(Rect padding)

Return in padding the insets suggested by this Drawable for placing
content inside the drawable’s bounds.

void

inflate)(Resources r, XmlPullParser parser, AttributeSet attrs)

void

invalidateDrawable)(Drawable who)

Called when the drawable needs to be redrawn.

boolean

isStateful)()

Indicates whether this view will change its appearance based on state.

void

scheduleDrawable)(Drawable who, Runnable what,
long when)

A Drawable can call this to schedule the next frame of its animation.

void

setAlpha)(int
alpha)

Specify an alpha value for the drawable.

void

setColorFilter)(ColorFilter cf)

Specify an optional colorFilter for the drawable.

boolean

setVisible)(boolean
visible, boolean restart)

Set whether this Drawable is visible.

void

unscheduleDrawable)(Drawable who, Runnable what)

A Drawable can call this to unschedule an action previously scheduled
with scheduleDrawable(Drawable,
Runnable, long)
.

而大家无独有偶所用的Drawable里面有二个措施:

  • The setLevel(int) method allows the client to supply a single
    continuous controller that can modify the Drawable is displayed,
    such as a battery level or progress level. Some drawables may modify
    their imagery based on the current level.

那正是设置截取比例的。
