[parfait evouna]

Hi everybody,

I would like to convert a ".tiff" image to a ".jpeg"; is there a possibility in a macro language of ImageJ?

Thank you for the help.

For instance:

run("Input/Output...", "jpeg=100 gif=-1 file=.txt copy_row save_column save_row");
open("D:\\Maria\\temp_image.tif");
saveAs("Jpeg", "D:\\Maria\\temp_image.jpg");

You could also use Process>Batch>Convert (just use Macros>Record to record the macro code).

It is possible. Here is an example:

  setBatchMode(true);
  call("ij.io.FileSaver.setJpegQuality", 85);
  dir = getDirectory("home");
  open(dir+"image.tif");
  saveAs("Jpeg", dir+"image.jpg");

To convert a folder of images to JPEG, use the Process>Batch>Convert command.

As we know, TIFF is a document format, while jpeg is an image form. So, if we want to convert tiff document to jpeg, I think we need to finish an imtermediary step, that is rendering TIFF document into image file. And then, we can take the easy image to image conversion method to convert to jpeg image.


Private Function GetPage(pageIdx As Integer) As BasePage Implements TIFFDocument.GetPage
End Function
Private Function toImage() As BaseImage Implements TIFFPage.toImage
End Function
Private Function toImage(width As Integer, height As Integer) As BaseImage Implements TIFFPage.toImage
End Function
Private Sub New(imagesource As List(Of REImage))
End Sub

Private Sub Convert(s As Stream, format As ImageFormat) Implements Image.Convert
End Sub
