I create a picture (kp) and set the dpi to 300 in Xojo code.
If I save it as a PNG, its correct.
ff is a folderitem.
If I save it with TiffPictureMBS as a TIFF file, I end up with the right number of pixels, but the image is 72dpi and thus way too large when printed by people who have no interest in being told how big it needs to be.
I get the same result when I use GMImageMBS methods
This is my TiffPictureMBS code:
Dim t As New TiffPictureMBS t.Pict = kp t.Copyright = szCopyRite t.DocumentName = szTitle t.HorizontalResolution = 300 //issue occurs whether these lines are present or not t.VerticalResolution = 300 t.ResolutionUnit = t.kResUnitInch If t.Create(ff) Then If t.WriteRGB Then t.Close // ok Else Break End If Else Break End If
Oddly, if I use this method, I get the right dpi, (but no access to other TIFF properties)
(Q: Why doesn’t Xojo use this to save in TIFF format?)
dim bs as BinaryStream bs = BinaryStream.Create(ff,true) bs.Write(kp.GetData(Picture.FormatTIFF)) bs.Close
