配置环境:
1、拷贝CxImage到项目目录
a、编译CxImage
b、cximage600_full\CxImage:所有的头文件和源文件
c、查找所有的lib
2、添加头文件目录
CxImage\Include
3、添加库文件目录
CxImage\lib
3、添加链接
cximage.lib
demod.lib
j2k.lib
jasper.lib
jbig.lib
jpeg.lib
png.lib
tiff.lib
zlib.lib
4、程序中添加头文件
#include "ximage.h"
基本用法
打开:
- CxImage image;
- if(image.load("name",类型))
- {
- CDC *pDC = GetDC();
- image.Draw(pDC->GetSafeHDC(),CRect rect(0,0,100,100));
- pDC->DeleteDC;
- }
旋转:
- CxImage smallImage;//旋转后的图片
- image.Rotate(90,&smallImage);//旋转90，并且保存到smallImage中
- smallImage.Save(保存的名字,类型);
镜像:
- CxImage ImgTmp = image;
- if(ImgTmp.Mirror())
- {
- image.Draw(.... , .....);
- }
缩放：
- <div class="container"><div class="line number1 index0 alt2"><code class="cpp plain">CxImage samllImg; </code></div><div class="line number2 index1 alt1"><code class="cpp spaces"></code></div><div class="line number3 index2 alt2"><code class="cpp plain">image.Resample(新宽度,新高度,0,&smallImg); </code></div><div class="line number4 index3 alt1"><code class="cpp spaces"></code></div><div class="line number5 index4 alt2"><code class="cpp plain">smallImg.Save(</code><code class="cpp string">"自定第一大小.jpg"</code><code class="cpp plain">,CXIMAGE_SUPPORT_JPG);</code></div></div>
剪辑：
- CDC *pDC=GetDC();
- UpdateData();
- CxImage smallImg;
- tempimage.Crop(CRect(m_xTop,m_yTop,m_xWidth,m_yHeiht),&smallImg);
- smallImg.Save("剪辑图片.jpg",CXIMAGE_SUPPORT_JPG);
- smallImg.Draw(pDC->GetSafeHdc(),CRect(40,70,picwidth,picheight));
- pDC->DeleteDC();
混合：
- CDC *pDC=GetDC();
- CxImage smallImg;
- smallImg.Load("混合源文件.jpg",CXIMAGE_SUPPORT_JPG);
- tempimage.Mix(smallImg,CxImage::OpAvg,0,0,true);
- tempimage.Save("Mix混合.jpg",CXIMAGE_SUPPORT_JPG);
- tempimage.Draw(pDC->GetSafeHdc(),CRect(40,70,picwidth,picheight));
