}Crop(Rectangle)
打破图像。
public override void Crop(Rectangle rectangle)Parameters
rectangle Rectangle
直角。
GetOriginalOptions()
获得基于原始文件设置的选项。这可能有助于保持原始图像的细节深度和其他参数不变。例如,如果我们加载一张黑白的PNG图像,每像素1比特,然后使用Aspose.Imaging.DataStreamSupporter.Save(System.String)方法,输出PNG图像,每像素将产生8位。要避免它,并以每像素1比特保存PNG图像,使用此方法获得相应的储蓄选项并通过它们。在 Aspose.Imaging.Image.Save(System.String,Aspose.Imaging.ImageOptionsBase)方法作为第二个参数。
public override ImageOptionsBase GetOriginalOptions()Returns
基于原始文件设置的选项。
ReleaseManagedResources()
释放管理资源 确保没有未管理资源在这里释放,因为它们可能已经释放了。
protected override void ReleaseManagedResources()RemoveMetadata()
删除此图像示例 meta 数据 通过设置此 Aspose.Imaging.Xmp.IHasXMPData.xmp Data 和 _ www.exif.ihas Exif。 零.
public override void RemoveMetadata()Resize(int , int , resizeType)
恢复图像。
public override void Resize(int newWidth, int newHeight, ResizeType resizeType)Parameters
newWidth int
新的宽度。
newHeight int
新高度。
resizeType ResizeType
回归类型。
Rotate(彩色 , 彩色 , 彩色)
旋转图像周围的中心。
public override void Rotate(float angle, bool resizeProportionally, Color backgroundColor)Parameters
angle float
旋转的角度在度,积极的值会旋转时钟。
resizeProportionally bool
如果设置为“真实”,您的图像大小将根据旋转直角(角点)的投影而改变,否则它会使尺寸不受触摸,只有内部图像内容被旋转。
backgroundColor Color
背景的颜色。
SaveData(Stream)
保存数据。
protected override void SaveData(Stream stream)Parameters
stream Stream
流来保存数据。
UpdateDimensions(int , int , int)
更新图像尺寸。
protected override void UpdateDimensions(int newWidth, int newHeight)Parameters
newWidth int
新图像宽度。
newHeight int
新图像高度。
