The IGIF interface is designed to configure output files to be saved in GIF format.
Properties
Enum ColorSpace
Defines the bit depth of the resulting image measured as the number of bits representing each pixel. It is both readable and writable.
Constant
Value
Description
CS_BLACKWHITE
1
Black and white image (1 bit per pixel)
CS_16COLORS
4
Color image, 16 colors (4 bits per pixel)
CS_16GRAYSCALE
132
Grayscale image (16 hues, 4 bits per pixel)
CS_256COLORS
8
Color image, 256 colors (8 bits per pixel)
CS_256GRAYSCALE
136
Grayscale image (256 hues, 8 bits per pixel)
Float FrameDelay
Defines the delay (in seconds) between frames in multi-page (animated) GIF files. It is both readable and writable.
Enum Multipage
Helps manage the process of creating multi-page output files. It is both readable and writable.
Constant
Value
Description
MM_SINGLE
0
Each page of the source document and every one-page document are saved as separate files
MM_MULTI
2
Each multi-page source document is saved as a single multi-page file
MM_APPEND
3
The content of all documents processed is saved in a single multi-page file
Enum Smoothing
Defines the dithering mode applied to half-tone transitions and used to reduce stepwise rendering when representing downsampled images. Dithering is applied only if the ColorSpace property has one of the following values: CS_BLACKWHITE, CS_16COLORS, CS_16GRAYSCALE, CS_256COLORS. It is both readable and writable.
Constant
Value
Description
SM_HQ
1
High-quality dithering is enabled to optimize for output image quality
SM_FAST
0
Fast dithering is used to optimize for conversion speed
Examples
Visual Basic 6
Dim objUDC As IUDC
Dim itfPrinter As IUDCPrinter
Dim itfProfile As IProfile
Set objUDC = New UDC.APIWrapper
Set itfPrinter = objUDC.Printers("Universal Document Converter")
Set itfProfile = itfPrinter.Profile
' Set GIF as current output file format
itfProfile.FileFormat.ActualFormat = FMT_GIF
itfProfile.FileFormat.GIF.ColorSpace = CS_COLOR_256
itfProfile.FileFormat.GIF.Smoothing = SM_HQ
itfProfile.FileFormat.GIF.Multipage = MM_MULTI
itfProfile.FileFormat.GIF.FrameDelay = 10
