PDFEdit_Layer.PDEColorSpace (PDFL)

	Typedef
	PDEColorSpace A reference to a color space used on a page in a PDF file. The color space is part of the graphics state attributes of a PDEElement.

	Union
	PDEColorSpaceStruct A color space structure for PDEColorSpaceCreate(). See Section 4.5 in the PDF Reference for information on color spaces.

	Method
	PDEColorSpace PDEColorSpaceCreate(ASAtom family, PDEColorSpaceStruct* csStruct) Creates a new color space object of the specified type.
	PDEColorSpace PDEColorSpaceCreateFromCosObj(const CosObj* cosObjP) Creates a new color space object from a Cos object.
	PDEColorSpace PDEColorSpaceCreateFromName(INASAtom name) Creates a new color space object.
	PDEColorSpace PDEColorSpaceCreateInCosDoc(INASAtom family, INPDEColorSpaceStruct* csStruct, INCosDoc cosDoc) Creates a color space object like PDEColorSpaceCreate(), except that the client can specify the CosDoc in which the color space object is created.

PDEColorSpaceGetBase

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASAtom PDEColorSpaceGetBase(INPDEColorSpace colorSpace)

Gets the name of the base color space. This is a helper routine for indexed color spaces.

Call this method to obtain the base color space and color values for an uncolored pattern in PDFEdit.

Parameters

colorSpace —

The base color space.

Returns

The ASAtom for the name of the base color space. Use ASAtomGetString() to obtain a C string for the ASAtom.

See Also

PDEColorSpaceGetBaseNumCompsNote that the base color values are in the color array in the PDEColorValue field for stroke and fill of a PDEGraphicStateP. Or, they are in the colorObj2 object if the base color space is DeviceN. To get the color values, a client gets the base color space, determines the type and number of components of the value, and looks them up in the PDEColorValue field.

Exceptions

peErrUnknownPDEColorSpace
peErrWrongPDEObjectType

Since

PI_PDFEDIT_READ_VERSION >= 0x00040000

Examples

if (PDEColorSpaceGetBase(srcColorSpace) == ASAtomFromString("DeviceRGB"))

File: PERProcs.h

Line: 1291

PDEColorSpaceGetBaseNumComps

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASInt32 PDEColorSpaceGetBaseNumComps(INPDEColorSpace colorSpace)

Gets the number of components in the base color space of an indexed color space.

For example, for [/ Indexed / DeviceRGB...], the number of components is 3.

Parameters

colorSpace —

IN/OUT The indexed color space.

Returns

The number of components in colorSpace.

Exceptions

peErrUnknownPDEColorSpace
peErrWrongPDEObjectType

Since

PI_PDFEDIT_READ_VERSION >= 0x00040000

Examples

ASInt32 baseNumComps = PDEColorSpaceGetBaseNumComps(srcColorSpace);

File: PERProcs.h

Line: 1612

PDEColorSpaceGetCosObj

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





void PDEColorSpaceGetCosObj(INPDEColorSpace colorSpace, OUTCosObj* cosObjP)

Gets the CosObj representation of the color space object.

For image masks, use PDEElementGetGState() to obtain color information.

Parameters

	`colorSpace` —	IN/OUT The color space whose Cos object is obtained.

	`cosObjP` —	IN/OUT (Filled by the method) The Cos object for the color space.

Exceptions

peErrWrongPDEObjectType

Since

PI_PDFEDIT_READ_VERSION >= 0x00040000

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 refer to it no further in your code.

File: PERProcs.h

Line: 1236

PDEColorSpaceGetCTable

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





void PDEColorSpaceGetCTable(INPDEColorSpace colorSpace, OUTASUns8* colorTableP)

Gets the component information for an indexed color space.

Parameters

	`colorSpace` —	IN/OUT The color space whose component information table is obtained.

	`colorTableP` —	IN/OUT (Filled by the method) The color lookup table, which is `numComps * (hiVal + 1)` bytes long, where `numComps` is the number of components in the base `colorSpace`. Each entry in the table contains `numComps` bytes, and the table is indexed from `0` to `hiVal`, where `hiVal` is the highest index in the color table. The table is indexed from `0` to `hival`, thus the table contains `hival + 1` entries.

Exceptions

peErrUnknownPDEColorSpace
peErrWrongPDEObjectType

Since

PI_PDFEDIT_READ_VERSION >= 0x00040000

Examples

PDEColorSpaceGetCTable (srcColorSpace, bufLUT);

File: PERProcs.h

Line: 1326

PDEColorSpaceGetHiVal

()

Product availability: PDFL

Platform availability: Macintosh, Windows, UNIX

Syntax





ASInt32 PDEColorSpaceGetHiVal(INPDEColorSpace colorSpace)

Gets the highest index for the color lookup table for an indexed color space. Since the color table is indexed from zero to hiVal, the actual number of entries is hiVal + 1.
