Define	Value	Description
ANNCALIBRATE_EXISTING	[0x0002]	Calibrates the hObject Ruler, and calibrates all other rulers and polyrulers in the container to have a matching calibration.
ANNCALIBRATE_NEW	[0x0004]	Any new ruler and polyruler created through automation will have a matching calibration to hObject Ruler.
ANNCALIBRATE_THIS	[0x0001]	Calibrates the hObject Ruler to be dCalibrateLength and uCalibrateUnit. All existing and new rulers are unaffected.
DOCWRT_ALTOXML_PlainText	[0x00000002]	If set, the font information will be discarded and all the text will use the same font.
DOCWRT_ALTOXML_ShowGlyphInfo	[0x00000004]	If set, extra information is displayed for each glyph (position, bounding rectangle).
DOCWRT_ALTOXML_ShowGlyphVariants	[0x00000008]	If set, text from OCR will display variants for some glyphs.
DOCWRT_ALTOXML_Sort	[0x00000001]	If set, the text will be sorted.
ELO2_IGNORE_EMBEDDED_ICC_PROFILE	[0x00000020]	Ignore the ICC profile embedded in the file (if any) - useful mainly for loading TIFF/JPEG CMYK/LAB files.
ESO2_PDF_LINEARIZED	[0x00080000]	Linearize the PDF file after save.
EXOBJ_8_CONNECTIVITY	[0x0001]	Pass to enable 8-way connectivity (diagonals), otherwise 4-way (only NSEW).
EXOBJ_CHECK_CONTAINER_SUBCHILDREN	[0x0080]	(Requires _IGNORE_CONTAINERS) Check the number of children in a container by recursing to lower objects (not just immediate children).
EXOBJ_CHECK_FOR_TABLES	[0x0100]	(Requires _CHECK_CONTAINER_SUBCHILDREN) When filtering out a container, attempt to preserve the cell containers as children (refer to dTableMaxBorderPercent).
EXOBJ_CONTENTBOUND_OPTIMIZED_FOR_REPETITION	[0x1]	Cache certain calculations from this iteration for use in consecutive calls.
EXOBJ_DETECT_CHILDREN	[0x0004]	Detect the children for each object, and output as a tree of nested objects.
EXOBJ_DIRECTION_EAST	[0]	The next outline point is to the right
EXOBJ_DIRECTION_NORTH	[1]	The next outline point is above
EXOBJ_DIRECTION_SOUTH	[3]	The next outline point is below
EXOBJ_DIRECTION_WEST	[2]	The next outline point is to the left
EXOBJ_FILTER_INVERT_RANGE	[0x2]	Invert the range (min <= filtered out <= max [instead of: filtered out < min or max < filtered out]).
EXOBJ_FILTER_REPORT_REMOVED_OBJECTS	[0x1]	Return a new list containing the filtered out objects (refer to pRemoved).
EXOBJ_FLATTEN	[0x0800]	(Requires _DETECT_CHILDREN) Flatten the final lists to store the children of an object immediately after the parent, rather than in a tree structure. Note: Using _SORT_TOPLEFT is applied after the flattening and will remove the parent-child ordering.
EXOBJ_IGNORE_CONTAINERS	[0x0040]	(Requires _DETECT_CHILDREN) Ignore containers during extraction (refer to uContainerMinCount).
EXOBJ_IGNORE_LARGE_NOISE	[0x0020]	Ignore large noise during extraction (refer to nLargeNoiseThreshold).
EXOBJ_IGNORE_SMALL_NOISE	[0x0010]	Ignore small noise during extraction (refer to nSmallNoiseThreshold).
EXOBJ_LOCATION_AFTER	[0]	Add pObject to pTargetList after pObjectNeighbor.
EXOBJ_LOCATION_BEFORE	[1]	Add pObject to pTargetList before pObjectNeighbor.
EXOBJ_LOCATION_CHILD	[2]	Add pObject to the end of pObjectNeighbor->pChildren.
EXOBJ_LOCATION_SIBLING	[3]	Add pObject to the end of pObjectNeighbor->pSiblings.
EXOBJ_OUTLINE	[0x0002]	Extract pixels along each object's outline.
EXOBJ_REGION_HORIZONTAL	[0x1]	Extract the region as horizontal segments.
EXOBJ_REGION_VERTICAL	[0x2]	Extract the region as vertical segments.
EXOBJ_REPORT_IGNORED	[0x0008]	Return ignored noise/containers in their respective lists.
EXOBJ_SORT_TOPLEFT	[0x0400]	Sort the object lists in each EXOBJ_RESULT structure (sub-lists not sorted).
EXOBJ_USE_MULTICOLORS	[0x0200]	Extract objects for each specified color level (instead of just 1 BPP).
FILEINFO_GRAY8_ALPHA	[0x00400000]	This file contains 8-bit grayscale data + alpha.
FILEINFO_PALETTE8_ALPHA	[0x00800000]	This file contains 8-bit color palette data + alpha.
FILEINFO_PORTFOLIO	[0x01000000]	This file is portfolio (such as a PDF with collection schema).
MSE_DONTUSE_MULTITHREADING	[0x0040]	Do not use multi-threading (Use this with single-core CPUs).
PDF_ENHANCE_THIN_LINES	[0x00000004]	If set, enhance thin lines (this is the default). If not set, thin lines are not enhanced.
XLS_FLAGS_SHOWGRIDLINES	[0x00000040]	When set, the sheet's grid lines will be rendered.
