symbian 显示位图和SVG图

核心提示：{EMbmGraphic_bmpImage1,EMbmGraphic_bmpImage2,EMbmGraphic_bmpImage2_mask};在用完后要删除位图对象//在析构函数中删除delete iBackgroundImage;delete iImage2;delete iImage2mask;//加载SVG图

{

EMbmGraphic_bmpImage1,

EMbmGraphic_bmpImage2,

EMbmGraphic_bmpImage2_mask

};

在用完后要删除位图对象

//在析构函数中删除

delete iBackgroundImage;

delete iImage2;

delete iImage2mask;

//加载SVG图

//声明部分

CFbsBitmap* iSoundSvg; //图片会把SVG图转换成位图，如果要实现矢量拉伸，需要重新加载

CFbsBitmap* iSoundSvgMask;

//实现部分

#include // AknIconUtils类的定义

#include // Bitmap enumeration

_LIT(KSvgPath, "\resource\apps\graphic_svg.mif");

//加载svg矢量图

TFileName svgFile (KSvgPath);

User::LeaveIfError (CompleteWithAppPath (svgFile));

AknIconUtils::CreateIconL(iSoundSvg, iSoundSvgMask, svgFile, EMbmGraphic_svgSound,EMbmGraphic_svgSound_mask);

//iSoundSvg=AknIconUtils::CreateIconL(svgFile,EMbmGraphic_svgSound);

AknIconUtils::SetSize(iSoundSvg, TSize(50,50), EAspectRatioNotPreserved);

AknIconUtils::SetSize(iSoundSvgMask, TSize(50,50), EAspectRatioNotPreserved);

//用后同样要删除

delete iSoundSvg;

delete iSoundSvgMask;

图片的显示过程：

//Draw()函数中实现

在设备绘图上下文类CWindowGc中绘制图形,CWindowGc是图形上下文CGraphicesContext类的派生类

//清空窗口上的内容

gc.SetPenStyle( CGraphicsContext::ENullPen );

gc.SetBrushColor( KRgbGray );

gc.SetBrushStyle( CGraphicsContext::ESolidBrush );

gc.DrawRect( aRect );

gc.SetBrushStyle( CGraphicsContext::ENullBrush );

//绘制客户区背景

//gc.BitBlt( Rect().iTl,iBackgroundImage );

gc.DrawBitmap(aRect,iBackgroundImage); //通过拉伸的方式放缩要目标矩形中

//在客户区的第一行绘制位图图标
