如何将Grafics中的数据保存到位图？ [英] How to save Data in a Grafics to a Bitmap ?

问题描述

如何将Grafics对象的全部或部分保存到图像/位图？

我尝试将Images.dll中的图像保存到BitMap文件。

我可以在图像中读到Grafics，但是当我尝试使用Bitmap

时结果是黑色的。

你能以某种方式剪辑Grafic和Paste它是否位于Bitmap？

How can you save all or a portion of the Grafics object to a Image/Bitmap ?
I am try to save the Images from Cards.dll to a BitMap file.
I can read in the Images to the Grafics, but when I try this with a Bitmap
the results are Black.
Can you somehow Clip the Grafic and Paste it into the Bitmap ?

我认为该示例在保存位图时存在错误24bit

颜色深度。

我相信每一行都需要在4字节边界上启动，或者沿着这些行开始

，它我已经深夜了，我还没有详细研究过，我只看了一下产品并且经历了类似的扭曲效果。

I think there is a bug in that sample when it saves bitmaps with 24bit
colour depth.
I believe each line needs to be started on a 4 byte boundary, or something
along those lines, it''s late at night and I haven''t studied it in detail, I
just looked at the output and have experienced a similar skewed effect.

谢谢，我已经完成了所有工作。

- 从cards.dll读取位图

- 保存为位图到文件

- 保存重新读取位图作为Jpeg

- 在WinCe中将位图打包到图形大小

- 在WinCe中保存为位图大小

- 保存重新读取位以WinCe尺寸映射为Jpeg

Thank you, I have gotten everything to work.
- Read in the Bitmap from cards.dll
- Save as Bitmap to File
- Save ReRead Bitmap as Jpeg
- Pack Bitmap to Graphics in WinCe Size
- Save as Bitmap in WinCe Size
- Save ReRead Bitmap as Jpeg in in WinCe Size
