DrawFlags

Values

DIRECTLY_IMPOSED

Directly imposed page.

DISPLAY_OVER_PRINT_PREVIEW

Display overprint preview.

DO_LAZY_ERASE

Erase the page while rendering only as needed.

DO_NOT_DOWNLOAD_FONTS

Do not download fonts during rendering.

Use this flag to prevent fonts from being downloaded/named to the output. Active when writing GDI output, such as to a metafile or printer on Windows.

DO_NOT_SUBSTITUTE_WORKING_SPACES

Do not substitute working spaces.

EMIT_PAGE_GROUP

Emit a page group.

FORCE_GDIPORT

If set, this forces the window draw code to attempt to use GDI instructions internally instead of assuming the incoming Platform device context contains enough information to allow APDFL to make a useful determination. Only honored on Windows. Useful when drawing to a window during print preview, when the supplied hDC is for the screen and does not allow APDFL to adequately instantiate drawing bounds.

IS_PRINT_PREVIEWING

Same as ForceGDIPort.

IS_PRINTING

The page is being printed.

IS_PSPRINTING

PostScript printing.

OPTIMIZE_FOR_INTERACTIVE

Set this flag for interactive viewers where the same PDF page may be re-drawn multiple times for viewing. This flag will allow re-drawing a PDF page (to change the positioning, zoom level or active smoothing & antialiasing, for example) to reuse some data elements from previous drawing operations, and will invoke a separate runtime thread for page operator parsing. However, this will increase the memory used for page display if enabled.

PASS_METADATATO_AGMPORT

Pass metadata to AGM port.

PASS_OCTO_AGMPORT

Pass optional content to AGM port.

PASS_OPITO_AGMPORT

Pass open prepress interface (OPI) to AGM port.

PRESERVE_PRIMARIES_K

Preserve the K channel of CMYK colors when rendering to a CMYK target colorspace. NOTE: The target colorspace must be CMYK and the source color must be CMYK or have an Alternate ColorSpace of CMYK in order for this flag to have an effect.

SUPPRESS_RASTER_ALPHA

Suppress raster alpha.

SWAP_COMPONENTS

Render colors in BGR order rather than RGB. It is only valid for calls to Page.DrawContents and only when outputing to an RGB colorspace.

USE_ANNOT_FACES

Draw annotation appearances.

USE_PRINTER_MARK_ANNOTS

Use printer's mark annotations.

USE_STAMP_ANNOTS_ONLY

If set, only consider Stamp annotations. This overrides UseAnnotFaces.

USE_TRAP_ANNOTS

Use trap network annotations.

WORKING_SPACES_ONLY_FOR_CHANGE

If this is set, only use a working space instead of a device space if the process color model of the target device is different than that of the source.

WRITING_TO_EMF

Indicate that the drawing is writing to an Enhanced MetaFile.

This prevents fonts from being downloaded, but may advise other flags in the future.
