Type Topic Plugin Version macOS Windows Linux iOS Targets
method TIFF MBS Images Plugin 4.2 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Reads a picture from a TIFF file.
Example 
dim f as FolderItem
dim t as TiffPictureMBS

f=SpecialFolder.Desktop.Child("008.tiff")
t=f.OpenAsTiffMBS(true)

if t<>Nil then
  msgbox str(t.width)+" x "+str(t.height)
else
  MsgBox "Problem?"
end if

This method is not depending on any library! It works without QuickTime even on System 7, but as it contains everything needed this method is around 270 KB big!
The plugin supports even more stuff like zlib compressed picture data or JPEGs embedded into TIFFs.

If the function returns nil, you can use a TiffPictureMBS subclass and use the methods there so you get error messages in the error event.

Setting HeaderOnly to true will ignore the actual picture data and load only the header data.

This function works with most Tiff formats, but has problems with some like 16 bit CMYK.
