I have a sequence of text binary images (matrix of 0 and 1) and I would
like to convert them to JPG or Tif, etc, but I could not find the way using ImageJ. Can anyone help me with this task? Thank you.

Waldir,
did you have a look at the ImageJ-Manual? <rsb.info.nih.gov/ij/docs/guide/user-guide.pdf> Although it doesn't cover the latest development it helps in your case. Have a look at the "Import Text Image"- and "Batch Processing"-section. The latter is quite convenient for format conversions. There is no sense to convert a binary image to JEPG because the JEPG-compression isn't made for binary images. Use the PNG-format (lossless compression) instead or simply zipped TIFF (lossless but less compressed) if you need compressed images. TIFF per se is OK if compression isn't required.

Hi,
You can use the File >Import > Text Image... command to import your binary matrix, and then save the result image using File > Save As > Jpeg... or File > Save As > Tiff... commands. Do this with the command recorder activated, and see the recorded macro statements. They will look like this : run("Text Image... ", "open=/Users/jmutterer/Desktop/binary.txt"); saveAs("Tiff", "/Users/jmutterer/Desktop/binary.tif"); You can use these to modify the example http://rsb.info.nih.gov/ij/macros/BatchProcessFolders.txt macro to sequentially import and save your images. In the latter macro, modify the processFile(path) function so that it looks like this : function processFile(path) { run("Text Image... ", "open=["+path+"]"); saveAs("Tiff", path); close(); } Jerome On 12 September 2014 14:47, Waldir Leite Roque <[hidden email]> wrote: > I have a sequence of text binary images (matrix of 0 and 1) and I would > like to convert them to JPG or Tif, etc, but I could not find the way using > ImageJ.

Thanks Herbie and Jerome,
I think I did not state the question appropriately. In fact, I have a binary matrix (text file not a text image) that I can load in ImageJ using Import>Text file. Now I would like to convert it to an image file (any format). Perhaps there is a plugin to do so, but I could not find one. Thanks again.

Waldir,
a text file is imported as readable text, a text image consisting of an array of numbers is imported as an image. The respective import options are "Import > Text File" and "Import > Text Image". Gabriel thanks for the confirmation!

Hi, Waldir.
Thanks for your nice sharing. As for me, I have seldom tried to deal with that. It is of great help. I wonder whether you have any exprience about pdf conversion process. Because there is something wrong with my pdf reader. I need convert pdf to text or other formats. Any suggestion will be appreciated. Thanks in advance. Lee |
