如何显示DIB或将其绘制到位图中 [英] How to display a DIB or draw it into a Bitmap

问题描述

我一直在互联网上寻找将DIB转换为位图的方法

但没有成功。


现在我是想知道这是否是我应该采取的方法。


我想要做的就是显示DIB或将其绘制成位图。


是否有图形方法可以提供帮助？


感谢

解决方案

System.Drawing.Bitmap对象是DIB。如果你想要一个DDB，请使用

GetHbitmap。如果你想用现有的DIB用CreateDIBSection或GDI DDB句柄构建一个Bitmap，请使用

构造函数之一的Bitmap类。


使用Graphics方法DrawImage显示或转换为不同的

PixelFormat。


如果你想与本机一起工作GDI API，然后使用CreateBitmap创建

a DDB或使用CreateDIBSection创建DIB。


要将一个转换为另一个，请使用BitBlt或任何一个其他GDIBitBlt

变种。

当我不问这个问题时，我讨厌它。


我想从剪贴板中获取DIB。


剪贴板产生的是一个MemoryStream。


我已经读过该流并获得了DIB中的调色板。


现在我想得到一个我认为很难从

流中读取的位图，因为它有很多变化。


我想这个这与将位图从文件

读入位图相同。


这就是我一直在寻找的东西。

谢谢

剪贴板产生的是一个MemoryStream。


您可以按原样从MemoryStream对象构造一个Bitmap对象。使用

使用流对象作为参数的Bitmap构造函数或方法。

I''ve been looking on the Internet for a way to convert a DIB to a Bitmap
without success.

Now I''m wondering if that is the approach I should be taking.

All I want to do is display the DIB or draw it into a Bitmap.

Is there a graphics method that can help?

thanks

解决方案

The System.Drawing.Bitmap object is a DIB. If you want a DDB, use
GetHbitmap. If you want to construct a Bitmap from an existing DIB created
with CreateDIBSection or a GDI DDB handle, use one of the constructors of
the Bitmap class.

Use the Graphics method DrawImage to display or convert to a different
PixelFormat.

If you want to work with the native GDI API, then use CreateBitmap to create
a DDB or use CreateDIBSection to create a DIB.

To convert one to the other, use BitBlt or any of the other GDI "BitBlt"
variations.

I hate it when I don''t ask the question right.

I want to get a DIB from the clipboard.

What the clipboard produces is a MemoryStream.

I have read that stream and obtained the palette in the DIB.

Now I''d like to get the bitmap which I think is harder to read from the
stream because there are so many variations.

I suppose at this point it is the same as reading the bitmap from a file
into a Bitmap.

That''s what I''ve been looking for.
Thanks

You can construct a Bitmap object from a MemoryStream object as is. Use the
Bitmap constructor or method which uses a stream object as an argument.
