PDEImageCreateInCosDocEx

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





PDEImage PDEImageCreateInCosDocEx(INPDEImageAttrsP attrsP, INASUns32 attrsSize, INASDoubleMatrixP matrixP, INASUns32 flags, INPDEColorSpace colorSpace, INPDEColorValueP colorValueP, INPDEFilterArrayP filtersP, INASStm dataStm, INASUns8* data, INASUns64 encodedLen, INCosDoc cosDoc)

Supersedes PDEImageCreateInCosDoc() and PDEImageCreateInCosDoc64() in Acrobat 10.0.

Creates an image object like PDEImageCreateInCosDoc(), except that the client can create an image with a large amount of data, and using a double precision transformation matrix.

The image data may be specified as a stream or as a buffer. If dataStm is non-NULL, data is ignored.

See PDEImageSetDataStm() for information on handling the stream.

The caller must dispose of dataStm after calling this method.

Call PDERelease() to dispose of the returned image object when finished with it.

Parameters

	`attrsP` —	IN/OUT A pointer to a PDEImageAttrs object with attributes of the image.

	`attrsSize` —	IN/OUT The size of the `attrsP` buffer in bytes.

	`matrixP` —	IN/OUT A pointer to an ASDoubleMatrix that holds the transformation matrix to use for the image.

	`flags` —	IN/OUT PDEImageDataFlags flags. If the kPDEImageEncodedData flag is set, and the data is provided directly (not as a stream), then `encodedLen` must specify the length of data.

	`colorSpace` —	IN/OUT The color space of the image. When the image is an image mask, `colorSpace` is the color space of the `colorValueP` argument.

	`colorValueP` —	IN/OUT A pointer to a PDEColorValue structure. If the image is an image mask, `colorValueP` must be provided.

	`filtersP` —	IN/OUT A pointer to a PDEFilterArray structure that specifies which filters to use in encoding the contents; it may be `NULL`. Filters will be used to encode the data in the order in which they are specified in the array.

	`dataStm` —	IN/OUT The stream holding the image data.

	`data` —	IN/OUT The image data. If `dataStm` is non-`NULL`, `data` is ignored. If there is a great deal of data, as for a large image, it is recommended you use the `dataStm` parameter for the image data or use the PDEImageCreateFromCosObjEx() method.

	`encodedLen` —	IN/OUT The encoded length of `data` in bytes.

	`cosDoc` —	IN/OUT The document in which the image is created.

Returns

The image.

PDEImageDataIsEncoded

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASBool PDEImageDataIsEncoded(INPDEImage image, OUTASUns32* encodedLenP)

Determines if image data is encoded or not. It is used only for inline images; it is not relevant to XObject images.

It always returns false for XObject images; XObject image data can be obtained from PDEImageGetData() or PDEImageGetDataStm(), either encoded or decoded.

If an inline image is obtained via PDEContentCreateFromCosObj() or related methods, the inline image data is always decoded. That is, if PDFEdit parses the stream, the data is always decoded. Only if PDEImageCreate() is used to explicitly create a new image using encoded data does PDEImageDataIsEncoded() return true.

Parameters

	`image` —	IN/OUT The image to examine.

	`encodedLenP` —	IN/OUT (Filled by the method) The length of the encoded data. If the data is encoded, the method returns `true`.

Returns

true if PDEImageGetData returns encoded data, false otherwise. It returns false for XObject images.

Note

(For the Adobe PDF Library v1 only) If you get the PDEColorSpace for an inline image and then get the CosObj for that color space with PDEColorSpaceGetCosObj(), this CosObj is limited. Cos objects that are the result of parsing inline dictionaries in the PDF page contents are a special class of Cos objects. You should never depend on these objects to last for the lifetime of the document. You should extract the information you need from the object immediately, and no longer refer to it in your code.
This method does not change the reference count of the returned PDEColorSpace.
