matlab: how to save TIFF series?

阅读更多关于 matlab: how to save TIFF series?

Lets say I have a 3D array 'img' (x, y, frame) and want to save it as a TIFF. So far I was doing it by saving one-by-one like this: for K=1:length(img(1, 1, :)) outputFileName = sprintf('img_%d.tif',K); imwrite(img(:, :, K), outputFileName); end cool, but what if I want to save it as a one tiff stack? How to do it? Thanks :) Clement J. The parameter ' append ' seems to correspond to what you want. outputFileName = 'img_stack.tif' for K=1:length(img(1, 1, :)) imwrite(img(:, :, K), outputFileName, 'WriteMode', 'append'); end EDIT: IMAGEJ has problems when opening multipletiffs saved like that.

Using Jquery and Ajax to save a file in ASP.Net

阅读更多关于 Using Jquery and Ajax to save a file in ASP.Net

I have a button that uses jQuery and ajax to call a server side script to create a text file and sends back the following response: Response.ContentType = "csv"; Response.AddHeader("Content-disposition", "attachment; filename=" + fName); Response.ContentType = "application/octet-stream"; Response.BinaryWrite(btFile); Response.End(); However, the save dialog does not appear. If I don't use ajax and perform a full postback with the same code, it works. Any ideas? Here is the jQuery code: $(function() { $('#reportButton').click(function() { $.ajax({ type: "POST", url: "GenerateReport.aspx", data:

阅读更多关于 Saving class-based view formset items with a new “virtual” column

I have a table inside a form, generated by a formset. In this case, my problem is to save all the items after one of them is modified, adding a new "virtual" column as the sum of other two (that is only generated when displaying the table, not saved). I tried different ways, but no one is working. Issues : This save is not working at all. It worked when it was only one form, but not for the formset I tried to generate the column amount as a Sum of box_one and box_two without success. I tried generating the form this way too, but this is not working: formset = modelformset_factory( Item, form

问题 I am developing a Newspaper like application. I'm wondering how to save webpages with the click of a button and display it at a later point in time. I googled for this in vain.
