}Crop(Rectangle)
Cropping the image.
public override void Crop(Rectangle rectangle)Parameters
rectangle Rectangle
The rectangle.
GetOriginalOptions()
Gets the options based on the original file settings. This can be helpful to keep bit-depth and other parameters of the original image unchanged. For example, if we load a black-white PNG image with 1 bit per pixel and then save it using the Aspose.Imaging.DataStreamSupporter.Save(System.String) method, the output PNG image with 8-bit per pixel will be produced. To avoid it and save PNG image with 1-bit per pixel, use this method to get corresponding saving options and pass them to the Aspose.Imaging.Image.Save(System.String,Aspose.Imaging.ImageOptionsBase) method as the second parameter.
public override ImageOptionsBase GetOriginalOptions()Returns
The options based on the original file settings.
ReleaseManagedResources()
Releases the managed resources. Make sure no unmanaged resources are released here, since they may have been already released.
protected override void ReleaseManagedResources()RemoveMetadata()
Removes this image instance metadata by setting this Aspose.Imaging.Xmp.IHasXmpData.XmpData and Aspose.Imaging.Exif.IHasExifData.ExifData values to null.
public override void RemoveMetadata()Resize(int, int, ResizeType)
Resizes the image.
public override void Resize(int newWidth, int newHeight, ResizeType resizeType)Parameters
newWidth int
The new width.
newHeight int
The new height.
resizeType ResizeType
The resize type.
Rotate(float, bool, Color)
Rotate image around the center.
public override void Rotate(float angle, bool resizeProportionally, Color backgroundColor)Parameters
angle float
The rotate angle in degrees. Positive values will rotate clockwise.
resizeProportionally bool
if set to true you will have your image size changed according to rotated rectangle (corner points) projections in other case that leaves dimensions untouched and only internal image contents are rotated.
backgroundColor Color
Color of the background.
SaveData(Stream)
Saves the data.
protected override void SaveData(Stream stream)Parameters
stream Stream
The stream to save data to.
UpdateDimensions(int, int)
Updates the image dimensions.
protected override void UpdateDimensions(int newWidth, int newHeight)Parameters
newWidth int
The new image width.
newHeight int
The new image height.
