IGPalette Object PlatformDIBImport Method	Imports a platform-specific DIB into the page.
ImagePtrGet Method	This method returns a pointer to the image's pixel data as stored internally in memory.
PalettePtrGet Method	This method returns a pointer to the palette of an image. It should only be used if the image is indexed.
PlatformDIBExport Method	This method exports an image as a platform-specific DIB.
PlatformDIBExportSizeCalc Method	Returns the size of a DIB (in bytes) that would be exported by PlatformDIBExport if the same parameters were used.
Rasterize Method	This method converts vector data associated with a page to the page DIB.
RasterPtrGet Method	This method returns a pointer to the beginning of pixel data for a given raster.
RemoveAllAlpha Method	This method removes all alpha channels from the IGPage.
RemoveAlpha Method	This method removes specified channel from the IGPage and shifts the remaining alpha channels.
SwapAlphas Method	This method swaps 2 alpha channels associated with IGPage.
UpdateExtraChannelInfoFrom Method	Creates a copy of the info array specified by ExtraChannelInfoand attaches it to IGPage's extra channel info array, replacing the old value.
UpdateGrayscaleLUTFrom Method	Creates or updates IGPage's grayscale LUT with values from the specified LUT.
