FW: Saving Tiff files
Locked

Hi All,
Could anyone help with the issue below? Thanks, Daniel ________________________________ From: Daniel Devlin Sent: 11 February 2013 13:26 To: [hidden email] Subject: Saving Tiff files Hi All, I am a university student in Northern Ireland. I have created an application with the purpose of trying to extract vessel maps from retinal images. I am using the ImageJ library to open a tiff file as I didn't have the resources to do this myself. I now have a greyscale image that is a 2D integer array and I would like to save this. I have tried to assign an Image to the ImageProcessor and save this but I keep getting an Access Denied message. Any help would be greatly appreciated. Thanks, Daniel P.S Here is the code to attempt the save. //load.pc.getImage returns buffered image Image image = load.pc.getImage(); ImagePlus imagePlus = new ImagePlus(); imagePlus.setImage(image); imagePlus.setTitle(fileName); FileSaver saver = new FileSaver(imagePlus); saver.saveAsTiff(picker.getSaveDirectory()); -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |

Hi Daniel,
It sounds like the user of the code does not have user permissions to write data to the directory returned by picker.getSaveDirectory(). To test this try hardcoding a directory you know you can save to (like your user directory on the machine) and see what happens.

Hi Daniel,
> I keep getting an Access Denied message If you attempt to open a directory for writing as a regular file, "access denied" is a typical error message. So it may be that FileSaver.saveAsTiff(String) does not support directory arguments. Try something like: saver.saveAsTiff(new File(picker.getSaveDirectory(), myFileName).getAbsolutePath()); where "myFileName" is the desired file name.
