JpegEncoder Class |
An ImageEncoder that will write JPEG images to a Stream.
Inheritance HierarchyNamespace: Atalasoft.Imaging.Codec
Assembly: Atalasoft.dotImage (in Atalasoft.dotImage.dll) Version: 11.4.0.9.0.377 (.NET 4.5.2, x86)
SyntaxThe JpegEncoder type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | JpegEncoder() | Initializes a new instance of a JpegEncoder. |
| JpegEncoder(Int32) |
Initializes a new instance of the JpegEncoder specifying the quality.
|
| JpegEncoder(Int32, Int32) | Initializes a new instance of a JpegEncoder specifying the quality and smoothing. |
| JpegEncoder(Int32, Int32, Boolean) | Initializes a new instance of a JpegEncoder specifying the quality, smoothing, and progressive value.
|
Properties| Name | Description | |
|---|---|---|
 | AppMarkers | Gets or sets the JPEG APPn Markers that will be saved with the image. |
| ComText | Gets or sets COM Text Markers that are to be saved with the image. |
| DctMode | Gets or sets the DCT compression mode used for encoding. |
| ImageType | Get the ImageType associated with this Encoder Setting. |
| IptcTags | Gets or sets IPTC Metadata that will be saved with the image. |
| PhotoshopResources | Gets or sets Photoshop resources to be saved with the image. |
| Progressive | Gets or sets a value indicating if the image is saved progressively. |
| Quality | Gets or sets the quality level of the Jpeg as it's encoded to a file. Valid values are 1 - 100 with a
default of 75. |
| Smoothing | Gets or sets the smoothing level when saving a Jpeg image. |
| SupportedPixelFormats | Returns an array of pixel formats supported by this encoder. (Overrides ImageEncoder.SupportedPixelFormats.) |
| Xmp | Gets or sets a byte array containing XMP data. |
Methods| Name | Description | |
|---|---|---|
 | CopyJpegWithNewMarkers(Stream, Stream) | Performs a lossless copy of the JPEG image data into a new image while replacing the JPEG metadata with
new metadata. |
| CopyJpegWithNewMarkers(String, String) | These methods perform a lossless copy of the JPEG image data into a new image while replacing the JPEG
metadata with new metadata. |
| CopyJpegWithNewMarkers(Stream, Stream, JpegMarkerCopyFlags) | These methods perform a lossless copy of the JPEG image data into a new image while replacing the JPEG
metadata with new metadata. |
| CopyJpegWithNewMarkers(String, String, JpegMarkerCopyFlags) | These methods perform a lossless copy of the JPEG image data into a new image while replacing the JPEG
metadata with new metadata. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| IsPixelFormatSupported | Returns true if the given PixelFormat can be encoded with the derived encoder. (Inherited from ImageEncoder.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Save | Encode an AtalaImage as a Jpeg image to a stream. (Overrides ImageEncoder.Save(Stream, AtalaImage, ProgressEventHandler).) |
| SetDownsamplingFactors | Sets the downsampling factors used when compressing the image data. This will affect both quality and
file size of the saved image. |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
RemarksThis ImageEncoder can be passed into the the AtalaImage or Workspace objects when saving to specify a JPEG image.
Metadata can be written with the JPEG image including EXIF, IPTC and COM Comments. See the Atalasoft.Imaging.Metadata namespace for more information.
If the image being saved contains a ColorProfile, it will be embedded within the file.
