| Public method | GetImage(System.String format) | Saves the raster to a memory buffer. |
| Public method | GetImage(System.String format, AttributeVariable< System.Drawing.Color > colorTable, AttributeSet options) | Saves the raster to a memory buffer, with the given color table and options. |
| Public method | GetImage(System.String format, AttributeVariable< System.Drawing.Color > colorTable, AttributeSet options, Rectangle bounds, Crs crs) | Saves the raster to a memory buffer, with the given options and georeferencing information. |
GetImage(System.String format)
Saves the raster to a memory buffer.Syntax
public System.IO.Stream GetImage (
System.String format
)Parameters
The image format to use.
Return Value
A memory buffer containing the image.
Remarks
Similar to Save, but the image is returned to the application in a memory buffer instead of being written to a disk file. The format parameter is used to select image format, it should contain the file extension associated with the image format, for instance "gif" or "jpg".
See Supported Image Formats for details about the supported image formats.
GetImage(System.String format, AttributeVariable< System.Drawing.Color > colorTable, AttributeSet options)
Saves the raster to a memory buffer, with the given color table and options.Syntax
public System.IO.Stream GetImage (
System.String format,
AttributeVariable< System.Drawing.Color > colorTable,
AttributeSet options
)Parameters
The image format to use.
Specifies the color table, if the raster does not contain color information.
Format-specific image options.
Return Value
A memory buffer containing the image.
Remarks
Similar to Save, but the image is returned to the application in a memory buffer instead of being written to a disk file. The format parameter is used to select image format, it should contain the file extension associated with the image format, for instance "gif" or "jpg".
If the raster does not contain color information, this can be supplied with the colorTable parameter.
See Supported Image Formats for details about the supported image formats and which options that may be specified for each format.
GetImage(System.String format, AttributeVariable< System.Drawing.Color > colorTable, AttributeSet options, Rectangle bounds, Crs crs)
Saves the raster to a memory buffer, with the given options and georeferencing information.Syntax
public System.IO.Stream GetImage (
System.String format,
AttributeVariable< System.Drawing.Color > colorTable,
AttributeSet options,
Rectangle bounds,
Crs crs
)Parameters
The image format to use.
Specified the color table, if the raster doesn't contain color information.
Format-specific image options.
The geographic bounds of the image.
The coordinate reference system of the image.
Return Value
A memory buffer containing the image.
Remarks
Similar to Save, but the image is returned to the application in a memory buffer instead of being written to a disk file. The format parameter is used to select image format, it should contain the file extension associated with the image format, for instance "gif" or "jpg".
If the raster does not contain color information, this can be supplied with the colorTable parameter.
Georeferencing information is only included for the TIFF format; for other formats bounds and crs are ignored.
