在Windows 10中截取截图的6种情势 简要介绍

 

截图对于分化的目标很要紧。它能够用于捕获台式机计算机上的别的内容的截图。所以,如若您选用Windows 10,你只怕不清楚怎么样截图,因为它是比较新的。由此,我们呈现了5种办法,您能够遮挡任何事物,特别是一旦您使用Windows 10.那边有6种形式在Windows 第10中学截取截图。

 

截图工具

【韦德国际1946】截图之截取整个网页,Windows通过原生情势截图内定窗口。Snipping工具是Windows的放权截图工具。每种Windows操作台式机Computer都配有此选项。在Windows 第10中学查找剪贴工具并不困难。只需在索求面板中找找剪贴工具就可以。选取Snipping Tool应用程序。当Snipping工具张开时,单击新建以捕获新的显示屏截图。

 

Windows Shift S

使用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,并彰显贰个光标,您能够在显示屏上绘制要在显示屏截图中捕获的区域。绘制要捕获的区域并释放鼠标光标。

 

打字与印刷显示器

点击键盘上的Prtsc按键。按按键捕获整个显示屏。今后展开贰个图像编辑器,如Paint。按Ctrl

  • V粘贴内容。裁剪后保存图像。

 

Windows键 打字与印刷显示屏

此选项捕获您的显示器截图并自行保存。要捕获整个显示屏并自动保存荧屏截图,请点击Windows Key PrtScn。荧屏会暗淡一分钟,让您领会显示器截图已被捕获。未来找到保存的快速照相在偏下职分图片> Screenshots文件夹。

 

Windows键 H

一旦要捕获整个显示器举行分享,能够使用Windows Key H键盘急忙方式。那将捕获整个荧屏。

 

Alt 打印荧屏

要急忙切换活动窗口,请使用键盘快速键Alt PrtScn。那将捕捉您当前活动的窗口,并将截图复制到剪贴板。您将需求在图像编辑器中开采镜头以保

MFC通过系统API将点名窗口导出为图片,方法之一:

来点轻松分享,明早自己豁然想截取浏览器里面张开的网页,是整二个网页,怎么办额?有三种缓和方案

在Android的运用中,有的时候候我们想单独展现一部分图像,那时候将供给图形截图。

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

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

1、随便截取图像的主意,以下我们具体介绍一下android中的主要类——Bitmap

{


public final class

HDC  hDC = ::GetDC(hWnd); //获取显示器DC

使用Firefox截图

首先步:张开Firefox步入调节台

shift F2 

第二部:能够扩充截图了

  • 截取当前全体网页并下载保存
screenshot fileName --fullpage 
  • 延迟截图
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的全套用到措施,大家要熟习记住:

国有方法

Copy the pixels from the buffer, beginning at the current position, overwriting the bitmap's pixels.

void

copyPixelsToBuffer)(Buffer dst)

Copy the bitmap's pixels into the specified buffer (allocated by the caller).

static Bitmap

createBitmap)(Bitmap src)

Returns an immutable bitmap from the source bitmap.

static Bitmap

createBitmap)(int[] colors, int width, int height, Bitmap.Config config)

Returns a immutable bitmap with the specified width and height, with each pixel value set to the corresponding value in the colors array.

static Bitmap

createScaledBitmap)(Bitmap src, int dstWidth, int dstHeight, boolean filter)

int

describeContents)()

No special parcel contents.

void

int

getDensity)()

Returns the density for this bitmap.

final int

getHeight)()

Returns the bitmap's height

byte[]

getNinePatchChunk)()

Returns an optional array of private data, used by the UI system for some bitmaps.

int

getPixel)(int x, int y)

Returns the Color at the specified location.

void

getPixels)(int[] pixels, int offset, int stride, int x, int y, int width, int height)

Returns in pixels[] a copy of the data in the bitmap.

final int

getRowBytes)()

Return the number of bytes between rows in the bitmap's pixels.

int

getScaledHeight)(int targetDensity)

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

int

getScaledHeight)(DisplayMetrics metrics)

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

int

getScaledHeight)(Canvas canvas)

Convenience for calling getScaledHeight(int) with the target density 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

getScaledWidth)(Canvas canvas)

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

final int

getWidth)()

Returns the bitmap's width

final boolean

hasAlpha)()

Returns true if the bitmap's config supports per-pixel alpha, and if the pixels may contain non-opaque alpha values.

final boolean

isMutable)()

Returns true if the bitmap is marked as mutable (i.e.

final boolean

isRecycled)()

Returns true if this bitmap has been recycled.

void

prepareToDraw)()

Rebuilds any caches associated with the bitmap that are used for drawing it.

void

recycle)()

Free up the memory associated with this bitmap's pixels, and mark the bitmap as "dead", meaning it will throw an exception if getPixels() or setPixels() is called, and will draw nothing.

void

setDensity)(int density)

Specifies the density for this bitmap.

void

setPixel)(int x, int y, int color)

Write the specified Color into the bitmap (assuming it is mutable) at the x,y coordinate.

Replace pixels in the bitmap with the colors in the array.

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关键方法:

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.

第一个參数source就是道理当然是那样的的Bitmap对象,前边的多个參数分别表示截取的范围。

2、另一种方法,不是轻易截取图形。而是从图像的一端(上、下、左、右)截取图像。也可以选择图像截取能源,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>

接下来大家能够透过ClipDrawable获取要截取的图像:

public class

HDC  hDCMem = ::CreateCompatibleDC(hDC); //创立包容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
  • 千帆竞发截图了
gnome-web-photo -t 0 --mode=photo URL fileName.png 

小心:UPRADOL为您要截取网页的链接。

假定使用桌面LinuxPC呢,推荐应用Firefox,Firefox截图极高清,轻便的享受!

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).

而大家习认为常所用的Drawable里面有叁个办法:

  • 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.

这就是设置截取比例的。
