EmfPlusFilterType
Inheritance: java.lang.Object, com.aspose.ms.System.ValueType, com.aspose.ms.System.Enum
public final class EmfPlusFilterType extends System.Enum
The FilterType enumeration defines types of filtering algorithms that can be used for text and graphics quality enhancement and image rendering.
Fields
Field | Description |
---|---|
FilterTypeNone | Specifies that filtering is not performed. |
FilterTypePoint | Specifies that each destination pixel is computed by sampling the nearest pixel from the source image. |
FilterTypeLinear | Specifies that linear interpolation is performed using the weighted average of a 2x2 area of pixels surrounding the source pixel. |
FilterTypeTriangle | Specifies that each pixel in the source image contributes equally to the destination image. |
FilterTypeBox | Specifies a box filter algorithm, in which each destination pixel is computed by averaging a rectangle of source pixels. |
FilterTypePyramidalQuad | Specifies that a 4-sample tent filter is used. |
FilterTypeGaussianQuad | Specifies that a 4-sample Gaussian filter is used, which creates a blur effect on an image. |
FilterTypeNone
public static final byte FilterTypeNone
Specifies that filtering is not performed.
FilterTypePoint
public static final byte FilterTypePoint
Specifies that each destination pixel is computed by sampling the nearest pixel from the source image.
FilterTypeLinear
public static final byte FilterTypeLinear
Specifies that linear interpolation is performed using the weighted average of a 2x2 area of pixels surrounding the source pixel.
FilterTypeTriangle
public static final byte FilterTypeTriangle
Specifies that each pixel in the source image contributes equally to the destination image. This is the slowest of filtering algorithms.
FilterTypeBox
public static final byte FilterTypeBox
Specifies a box filter algorithm, in which each destination pixel is computed by averaging a rectangle of source pixels. This algorithm is useful only when reducing the size of an image.
FilterTypePyramidalQuad
public static final byte FilterTypePyramidalQuad
Specifies that a 4-sample tent filter is used.
FilterTypeGaussianQuad
public static final byte FilterTypeGaussianQuad
Specifies that a 4-sample Gaussian filter is used, which creates a blur effect on an image.
