The following members have been added to the existing types:
| Member | Description |
|---|---|
| Leadtools.Converters.ConvertFromImageOptions.LinkImage |
Uses the data from the source's native image object without making a copy.
In WinRT, it links the RasterImage to a WriteableBitmap. |
| Leadtools.Converters.ConvertFromImageOptions.AutoFreeLinkImage | Automatically frees the linked native image object when the RasterImage is disposed. |
| Leadtools.Converters.ConvertFromImageOptions (Java) | Options for converting an Android **android.graphics.Bitmap** to a LEADTOOLS RasterImage object. |
| Leadtools.Converters.ConvertFromImageOptions.None (Java) | Default |
| Leadtools.Converters.ConvertFromImageOptions.LinkImage (Java) | Uses the data from the source's native image object without making a copy. |
| Leadtools.Converters.ConvertFromImageOptions.AutoFreeLinkImage (Java) | Automatically frees the linked native image object when the RasterImage is disposed. |
| Leadtools.Converters.ConvertToImageOptions.LinkImage |
Uses the data from the source's native image object without making a copy.
In WinRT, this links the RasterImage to a WriteableBitmap. |
| Leadtools.Converters.ConvertToImageOptions (Java) | Specifies options for converting a LEADTOOLS RasterImage object into an Android **android.graphics.Bitmap**. |
| Leadtools.Converters.ConvertToImageOptions.None (Java) | Default |
| Leadtools.Converters.ConvertToImageOptions.KeepAlphaValues (Java) |
If the source RasterImage is 32 or 64-bits/pixel, then use the alpha values from this alpha if the result of the conversion is also a 32 or 64-bits/pixel **android.graphics.Bitmap**. If this flag is not specified, the resulting **android.graphics.Bitmap** will always have an alpha value of all 1's (255 for 32-bit images or 65535 for 64-bit images) regardless of the alpha values in the source RasterImage. This can be useful when converting some 32-bit images that may have 0 for the alpha (such as BMP files) which translates into an **android.graphics.Bitmap** that is completely transparent. If this flag is specified, then the source image alpha values will be used as is. |
| Leadtools.Converters.ConvertToImageOptions.KeepViewPerspective (Java) |
Keep the original RasterImage view perspective. RasterImage objects support having an image data orientation other than the normal top-left orientation by using the RasterImage.ViewPerspective property. If the source RasterImage has a view-perspective other than RasterViewPerspective.TopLeft and this flag is specified, then the resulting **android.graphics.Bitmap** can be flipped, reversed or rotated. For example, if the source view-perspective is RasterViewPerspective.BottomLeft and this flag is specified in the conversion options, then the resulting **android.graphics.Bitmap** will be flipped. If this flag is not specified, then the conversion can flip, reverse or rotate the image data as needed to provide the correct (top-left) orientation for the **android.graphics.Bitmap**. |
| Leadtools.Converters.ConvertToImageOptions.IgnoreLowHighBitsOnGrayImages (Java) |
Do not use the grayscale bit window values when converting 12 or 16-bit grayscale RasterImage objects. The RasterImage object contains the RasterImage.LowBit and RasterImage.HighBit values that can be set to provide a Window into the image data. This is mostly used by medical applications during a window-leveling operation. If this flag is specified, the RasterImage.LowBit and RasterImage.HighBit values are ignored and all of the image data is used when converting the RasterImage into a **android.graphics.Bitmap**. If this flag is not specified, then only the image data between the RasterImage.LowBit and the RasterImage.HighBit is used. |
| Leadtools.Converters.ConvertToImageOptions.LinkImage (Java) |
Uses the data from the source's native image object without making a copy.
In Android, it links the RasterImage to a **android.graphics.Bitmap**. |
| Leadtools.Converters.RasterRegionConverter (Java) | Converts between a LEADTOOLS RasterRegion and Android **android.graphics.Path** object. |
| Leadtools.Converters.RasterRegionConverter.ConvertToPath(Leadtools.RasterRegion) (Java) | Converts a LEADTOOLS RasterRegion to an Android **android.graphics.Path** object. |
| Leadtools.Converters.RasterRegionConverter.ConvertFromPath(Path) (Java) | Converts an Android **android.graphics.Path** object to a LEADTOOLS RasterRegion. |
| Leadtools.Converters.RasterImageConverter.TestCompatible(Leadtools.RasterImage,Int32) (Java) | Determines if a RasterImage is compatible with the Android **android.graphics.Bitmap**. |
| Leadtools.Converters.RasterImageConverter.ConvertToImage(LTRasterImage,LTConvertToImageOptions,NSError) (Objective C) | Converts an LTRasterImage to an LTImage. |
| Leadtools.Converters.RasterImageConverter.ConvertToCGImage(LTRasterImage,LTConvertToImageOptions,NSError) (Objective C) | Converts an LTRasterImage to an CGImageRef. |
| Leadtools.Converters.RasterImageConverter.ConvertFromImage(LTImage,LTConvertFromImageOptions,NSError) (Objective C) | Converts an LTImage to an LTRasterImage. |
| Leadtools.Converters.RasterImageConverter.ConvertFromCGImage(CGImageRef,LTConvertFromImageOptions,NSError) (Objective C) | Converts a CGImageRef to a LTRasterImage. |

| Leadtools.Converters.RasterImageConverter.GetLinkedImage(Leadtools.RasterImage) (Java) | Gets the native image that the specified RasterImage is linked to. |
| Leadtools.Converters.RasterImageConverter.GetLinkedImage(Leadtools.RasterImage) (Objective C) | Gets the LTImage (UIImage/NSImage) image that the specified RasterImage is linked to. |
| Leadtools.Converters.RasterImageConverter.GetLinkedCGImage(Leadtools.RasterImage) (Objective C) | Gets the CGImageRef that the specified RasterImage is linked to. |
| Leadtools.Converters.LTBitmapHandleConverter (Objective C) | Converts a **LTImage** or **CImageRef** to and from a **BITMAPHANDLE** object. |
| Leadtools.Converters.LTBitmapHandleConverter.ConvertToImage(BITMAPHANDLE,LTConvertToImageOptions,NSError) (Objective C) | Converts a BITMAPHANDLE to an LTImage. |
| Leadtools.Converters.LTBitmapHandleConverter.ConvertToCGImage(BITMAPHANDLE,LTConvertToImageOptions,NSError) (Objective C) | Converts a BITMAPHANDLE to an CGImageRef. |
| Leadtools.Converters.LTBitmapHandleConverter.ConvertFromImage(BITMAPHANDLE,LTImage,LTConvertFromImageOptions,NSError) (Objective C) | Converts a **LTImage** to a **BITMAPHANDLE**. |
