配置環境:

1、拷貝CxImage到項目目錄

a、編譯CxImage

b、cximage600_full\CxImage:所有的頭文件和源文件

c、查找所有的lib

?

2、添加頭文件目錄

CxImage\Include

3、添加庫文件目錄

CxImage\lib

3、添加鏈接
cximage.lib
demod.lib
j2k.lib
jasper.lib
jbig.lib
jpeg.lib
png.lib
tiff.lib
zlib.lib

4、程序中添加頭文件

#include "ximage.h"

?

基本用法

打開:

[cpp]?view plaincopy

CxImage?image;???

if(image.load("name",類型))???

{???

????CDC?*pDC?=?GetDC();???

????image.Draw(pDC->GetSafeHDC(),CRect?rect(0,0,100,100));???

????pDC->DeleteDC;???

}??

旋轉:

[cpp]?view plaincopy

CxImage?smallImage;//旋轉后的圖片???

image.Rotate(90,&smallImage);//旋轉90，并且保存到smallImage中???

smallImage.Save(保存的名字,類型);???

?

鏡像:

[cpp]?view plaincopy

CxImage?ImgTmp?=?image;???

if(ImgTmp.Mirror())???

{???

image.Draw(....?,?.....);???

}??

?

?

縮放：

[cpp]?view plaincopy

<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(新寬度,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>??

?

剪輯：

[cpp]?view plaincopy

CDC?*pDC=GetDC();???

UpdateData();???

CxImage?smallImg;???

tempimage.Crop(CRect(m_xTop,m_yTop,m_xWidth,m_yHeiht),&smallImg);???

smallImg.Save("剪輯圖片.jpg",CXIMAGE_SUPPORT_JPG);???

smallImg.Draw(pDC->GetSafeHdc(),CRect(40,70,picwidth,picheight));???

pDC->DeleteDC();???

?

混合：

[cpp]?view plaincopy

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));???
