问题 I put an image inside an ImageView and have multitouch implemented to resize and move the image inside the ImageView. Now I need to save the resized image to a image file. I have tried the .getDrawingCache() but that image have the size of the ImageView. I want the image to show what the ImageView shows but with full resolution (larger than the ImageView). Any ideas? 回答1: You could hold a Bitmap Object in Background, which you can resize with this piece of code: Matrix matrix = new Matrix();

问题 I'm on a branch (let's say master), and I have some changes in my working dir. I get stuff working, but needing a lot of cleanup - so I'd like to save my current working dir to a branch just in case I need to go back to it. I'll definitely be deleting the branch later. In addition, I want to continue working on master EXACTLY where I was.

问题 Running the code, getting the old results... Indeed, forgot to save one of the edited .m files, again. What's the keyboard shortcut to save ALL open .m files at once? 回答1: You can add a shortcut for the Save All action (at least in R2015a which I am using). I chose CTRL+ALT+S : How you get there is described in the MATLAB documentation: On the Home tab, in the Environment section, click Preferences. Select MATLAB > Keyboard > Shortcuts. 来源： https://stackoverflow.com/questions/31336876/save

问题 I have a script that creates a vCard for members of staff when the 'Add Contact' button is clicked. I have this vCard in a variable, but I'm not really sure what to do with it next.

问题 I have a big array (1024x1024x360) and I want to save it to a mat file.

I'm using Matlab 2012a on Win7-64 machine, Why is that happening? 回答1: Earlier versions of Matlab couldn't save variables larger than 2 GB.

问题 How would you go about opening an .xml file that is within a .jar and edit it? I know that you can do... InputStream myStream = this.getClass().getResourceAsStream("xmlData.xml"); But how would you open the xmlData.xml, edit the file, and save it in the .jar? I would find this useful to know and don't want to edit a file outside of the .jar... and the application needs to stay running the entire time! Thank you! 回答1: Jar files are just .zip files with different file suffix, and naming

问题 I am trying to save each image in an array as a .PNG file (also as the right size, without scaling up because of retina mac dpi issues) and can't seem to find a solution.

问题 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 :) 回答1: 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,
