PngEncoder Class |
An ImageEncoder that will write Portable Network Graphics (PNG) 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 PngEncoder type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PngEncoder |
Initializes a new instance of the PngEncoder class.
|
| PngEncoder(ComTextCollection) | Initializes a new instance of a PngEncoder specifying the COM Text metadata to save. |
| PngEncoder(Color, Double, Boolean, ComTextCollection) | Initializes a new instance of a %PngEncoder% specifying the background color, gamma, interlace, and COM
Text value to save. |
Properties| Name | Description | |
|---|---|---|
 | BackgroundColor | Gets or sets the color to use as the default background color for Png images with alpha. |
| BackgroundIndex | Gets or sets the palette index or grayscale value to use as the default background color for colormapped
Png images with alpha. |
| ComText | Gets or sets the COM text metadata to save with the image. |
| Gamma | Gets or sets the gamma value to write to a PNG image. 0 will not write any value, 2.2 is a typical value
for PC's. Default 0. |
| Interlace | Gets or sets whether Png files are saved with a pixel row interlacing pattern. Defaults
False. |
| SupportedPixelFormats | Returns an array of pixel formats supported by this encoder. (Overrides ImageEncoderSupportedPixelFormats.) |
Methods| Name | Description | |
|---|---|---|
| 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 Png image to a stream. (Overrides ImageEncoderSave(Stream, AtalaImage, ProgressEventHandler).) |
| 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 PNG image.
If the image being saved contains a ColorProfile, it will be embedded within the file.
