Windows上的pngwriter lib [英] pngwriter lib on windows

问题描述

大家好
我需要从代码生成按钮图像(.png)并保存到磁盘.
我尝试使用lib pngwriter 0.5.4
完成在Windows XP上为Microsoft Visual C ++ .NET设置PNGWriter 指令，除了 pngwriter.lib 建筑，它会出错.

无法将参数3从``unsigned long *''转换为``png_uing_32''
找不到png_set_gray_1_2_4_to_8标识符
.....
和许多其他错误

.png gererate是否有更好的lib?
问题如何解决?

谢谢.

Hi All
I need generate button image (.png) from code and save to disk.
I try use lib pngwriter 0.5.4
Done all Setting Up PNGWriter for Microsoft Visual C++ .NET on Windows XP instructions except pngwriter.lib building, it takes error.

Can not convert parameter 3 from ''unsigned long *'' to ''png_uing_32''
png_set_gray_1_2_4_to_8 identifier not found
.....
and many other errors

Are there better lib for .png gererate?
How correct problem?

推荐答案

您可以使用GDI+

You may use the GDI+ Image::Save method[^] to write a png image file.
:)

正如CPallini所写，您可以使用 GDI + 中的Image类；如果您使用的是 ATL/MFC ，则可能更喜欢使用 CImage类(ATL/MFC) [

As CPallini already wrote, you may use the Image class from GDI+; if you are using ATL/MFC may you prefer using the CImage Class (ATL/MFC)[^] which is a wrapper for the GDI+ class.

GDI + 是完美的解决方案，谢谢:thumbsup :: thumbsup :: thumbsup:
