Description

COMM.PATH

AM_TID_LP | AM_TID_CHAR

<Path to the folder where ImageGear Core module is located>

Any string

Specifies the path to the folder containing ImageGear component modules. See IG_comm_comp_attach.

CPM.CMYK_PROFILE_PATH

AM_TID_LP | AM_TID_CHAR

<Path to the default CMYK profile; located in the same directory as ImageGear Core module.>

Any string

Specifies the path to the default CMYK color profile. See Using Color Profile Manager.

CPM.ENABLE_PROFILES

AM_TID_AT_BOOL

FALSE

FALSE, TRUE

Enables or disables the color profile manager. See Using Color Profile Manager.

CPM.ENABLE_RENDERING_INTENTS

AM_TID_AT_BOOL

FALSE

FALSE, TRUE

Enables or disables the usage of rendering intents in color profiles. By default, ImageGear uses Relative Colorimetric rendering intent. See Using Color Profile Manager.

CPM.RGB_PROFILE_PATH

AM_TID_LP | AM_TID_CHAR

<Path to the default RGB profile; located in the same directory as ImageGear Core module.>

Any string

Specifies the path to the default RGB color profile. See Using Color Profile Manager.

DIB.FILE_MAPPING.FLUSH_SIZE

AM_TID_INT

200

Any non-negative integer

Specifies the maximum size of a memory block in a DIB that can be processed without flushing the memory mapped file, in megabytes. Only used when "DIB.FILE_MAPPING.THRESHOLD"  is greater than zero. Does not affect 1-bit images. See Working with Gigabyte-Sized Images.

DIB.FILE_MAPPING.PATH

AM_TID_LP | AM_TID_CHAR

<Empty string. ImageGear uses the system temporary folder for memory mapped files.>

Any string

Specifies the path to a folder where memory mapped files will be stored. Only used when "DIB.FILE_MAPPING.THRESHOLD" is greater than zero. Does not affect 1-bit images. See Working with Gigabyte-Sized Images.

DIB.FILE_MAPPING.THRESHOLD

AM_TID_INT

0

Any non-negative integer

Specifies minimum DIB size, in megabytes, for which the memory mapped file shall be used. Zero means that the use of memory mapped files is disabled. Does not affect 1-bit images. See Working with Gigabyte-Sized Images.

DIB.PIX_ACCESS_USE_LEGACY_MODE

AM_TID_AT_LMODE

IG_PIX_ACCESS_MODE_LEGACY

IG_PIX_ACCESS_MODE_LEGACY = 0, IG_PIX_ACCESS_MODE_NEW = 1

Switches between “legacy” (14.4 and earlier) and “new” pixel access modes. See Pixel Access Modes.

FLTR.METADATA_FORMAT

AM_TID_LP | AM_TID_CHAR

“binary”

“binary”, “text”

Switches between binary and text representations for accessing metadata values. See Non-Image Data Format.

IO.BUFFER_SIZE

AM_TID_DWORD

262144

Any non-negative integer

Specifies the size of the internal buffer used for image reading. Set to 0 to disable bufferization. See Internal Stream Bufferization.

MULT.PREFER_DIRECTSHOW_FOR_AVI_MPEG

AM_TID_AT_BOOL

TRUE

FALSE, TRUE

If TRUE, DirectShow is preferred for *.avi,*.mpg,*.mpeg files over QuickTime. If FALSE, the application that is used to load the file depends on which component was attached first and detects the file. See MULT.PREFER_DIRECTSHOW_FOR_AVI_MPEG.

PDF.ENABLE_POSTSCRIPT

AM_TID_AT_BOOL

TRUE

FALSE, TRUE

Enables or disables PostScript support in PDF component. See Attaching the PDF Component to Core ImageGear.

PDF.HOST_FONT_PATH

AM_TID_LP | AM_TID_CHAR

<Parameter is not set. ImageGear uses the system fonts directory.>

Any string

Specifies path to the system font directory. See IG_PDF_initialize.

PDF.PDF_RESOURCE_PATH

AM_TID_LP | AM_TID_CHAR

<Parameter is not set. ImageGear looks for PDF resources in <COMM.PATH>\ Resources\PDF>

Any string

Specifies the path to the PDF resources directory. See IG_PDF_initialize.

PDF.PS_RESOURCE_PATH

AM_TID_LP | AM_TID_CHAR

<Parameter is not set. ImageGear looks for PDF resources in <COMM.PATH>\ Resources\PS>

Any string

Specifies the path to the PostScript resources directory. See IG_PDF_initialize.

PDF.TMP_PATH

AM_TID_LP | AM_TID_CHAR

<Parameter is not set. ImageGear selects PDF/PS temporary directory according to system settings.>

Any string

Specifies the path to the temporary directory for PDF component. See IG_PDF_initialize.

This parameter specifies the location where temp objects such as scratch PDF files, scratch PS files, and PS font cache are created. This parameter should be set before the PDF component is initialized with IG_PDF_initialize.

REC.RESOURCE_PATH

AM_TID_LP | AM_TID_CHAR

<Parameter is not set. ImageGear looks for Recognition component resources in <COMM.PATH>\ Resources\Recognition>

Any string

Specifies the path to the Recognition component’s resources directory. See IG_REC_initialize.

Specifies the typeface name of TrueType font used to display text objects, if the typeface is not defined in the source image.

The default font chosen by the system may not support the full range of Unicode characters, such as Chinese, Japanese, or Korean. In order to display such characters correctly, specify a font that supports them, e.g., Arial Unicode MS.

XMP.Parse

AM_TID_AT_BOOL

TRUE

FALSE, TRUE

Enables or disables the parsing of XMP stream when reading and writing metadata from/to image files. See Working with XMP Metadata.
