I’m encountering an issue with publishing PDFs using VBA. Despite having bitmaps in CorelDRAW with lower resolutions, the published PDF is converting all bitmaps to a higher resolution. How can I resolve this problem?
With ActiveDocument.PDFSettings .PublishRange = 1 ' CdrPDFVBA.pdfCurrentPage .PageRange = "1" .Author = "CorelDraw" .Subject = "" .Keywords = "" .BitmapCompression = 2 ' CdrPDFVBA.pdfJPEG .JPEGQualityFactor = 2 .TextAsCurves = True .EmbedFonts = True .EmbedBaseFonts = True .TrueTypeToType1 = True .SubsetFonts = True .SubsetPct = 80 .CompressText = True .Encoding = 1 ' CdrPDFVBA.pdfBinary .DownsampleColor = True .DownsampleGray = True .DownsampleMono = True .ColorResolution = 1200 'Resolution .MonoResolution = 2400 'Resolution * 2 .GrayResolution = 1200 ' Resolution .Hyperlinks = False .Bookmarks = False .Thumbnails = False .Startup = 0 ' CdrPDFVBA.pdfPageOnly .ComplexFillsAsBitmaps = False .Overprints = True .Halftones = False .MaintainOPILinks = False .FountainSteps = 999 .EPSAs = 0 ' CdrPDFVBA.pdfPostscript .pdfVersion = 0 ' CdrPDFVBA.pdfVersion12 .IncludeBleed = False .Bleed = 31750 .Linearize = False .CropMarks = False .RegistrationMarks = False .DensitometerScales = False .FileInformation = False .ColorMode = ColorSpace ' CdrPDFVBA.pdfNative '.UseColorProfile = True .ColorProfile = 1 ' CdrPDFVBA.pdfSeparationProfile .EmbedFilename = FileNameText.text '"" .EmbedFile = False .JP2QualityFactor = 2 .TextExportMode = 0 ' CdrPDFVBA.pdfTextAsUnicode .PrintPermissions = 0 ' CdrPDFVBA.pdfPrintPermissionNone .EditPermissions = 0 ' CdrPDFVBA.pdfEditPermissionNone .ContentCopyingAllowed = False .OpenPassword = "" .PermissionPassword = "" .EncryptType = 2 ' CdrPDFVBA.pdfEncryptTypeAES .OutputSpotColorsAs = OutputSpace ' CdrPDFVBA.pdfSpotAsSpot .OverprintBlackLimit = 100 .ProtectedTextAsCurves = True End With
understand these parameters and correct them to the ones you need
.ColorResolution = 1200 'Resolution.MonoResolution = 2400 'Resolution * 2.GrayResolution = 1200 ' Resolution
This is the DPI for color, gray and monochrome rasters
I understand it.
Those were defined for downsampling purposes but not for resampling purposes. Downsampling means if the image resolution is greater than "Resolution" then downsample to the resolution else unchanged.
this is also producing 72 dpi image to 300 dpi
although you have designed such an excellent UI.
Can I ask for your file - where such amazing things happen - for analysis? Just a few raster samples in the document that change the resolution from 72 to 300 as a result of the PDF conversion.
