Parameters

ImageID

GdPicture image identifier.

Data

Output parameter. The image data.

Length

Output parameter. The number of bytes wrote into the Data array.

ImageFormat

A member of the DocumentFormat enumeration. Currently supported formats are:

DocumentFormatBMP.

DocumentFormatJPEG.

DocumentFormatPNG.

DocumentFormatTIFF.

DocumentFormatGIF.

DocumentFormatJ2K (JPEG2000 codestream).

DocumentFormatJP2 (JPEG2000)

DocumentFormatTARGA.

DocumentFormatEXR.

DocumentFormatWBMP.

DocumentFormatXPM.

DocumentFormatPBM.

DocumentFormatWMF.

DocumentFormatWEBP.

EncoderParameter

Compression or encoding quality to use.

For JPEG format: the parameter defines the quality between 1 (lower) and 100 (higher).

For WebP format: the parameter defines the quality between 1 (lower) and 100 (higher - lossless encoding).

For TIFF format: the parameter defines the compression scheme to be used: 1 for none, 2 for RLE, 3 for CCITT3, 4 for CCITT4, 5 for LZW, 7 for JPEG, 32946 for Deflate and 65536 for automatic compression adjustment. For more options the SaveAsTiff() method taking a Stream object as parameter can be used.

For JPEG2000 format: the parameter defines the compression rate Between [1(MaxQuality - Lossless) ... 512(Poor quality)]. Default value is 16.

For PNG format: the parameter defines the compression level Between [0(no compression - faster encoding) ... 9(max compression - slower encoding)]. Default value is 6.

For other formats use 0.

Return Value

This method requires the Image Documents component to run.
