android show image in default gallery viewer
Gallery application does not accept URL for an image as part of the Intent. You need to save the image first. Then you can launch the default image viewer with something like this: Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*"); startActivity(intent);

How can I view the output of `git show` in a diff viewer like meld, kdiff3, etc
You can use git difftool to show a single commit. Say you want to see the commit with the sha1 abc123: git difftool abc123~1 abc123 (~1 tells git to move to the previous commit, so abc123~1 is the commit before abc123) If you use this regularly, you could make a custom git command to make it easier: Create a file called git-showtool somewhere on your $PATH with the following contents: git difftool $1~1 $1 Give that file execute permissions: chmod +x ~/path/to/git-showtool Use the command git showtool <sha1 or tag or ...> Profit.

Show converted mouse coordinates of an element with javascript
Here’s how to convert mouse coordinates to cell coordinates and display a tooltip This math calculates which 75x75 cell your mouse is inside: var col=parseInt(mouseX/75); var row=parseInt(mouseY/75); And here is the math to calculate a tip rectangle in the upper-right of that cell: var tipX=tipCol*75+75-tipWidth; var tipY=tipRow*75; You can use canvas to draw the tip inside the cell at your calculated coordinates: function tip(x,y){ var tipX=tipCol*75+75-tipWidth; var tipY=tipRow*75; ctx.beginPath(); ctx.rect(tipX,tipY,tipWidth,tipHeight); ctx.fillStyle="ivory"; ctx.fill(); ctx.fillStyle="blue"; ctx.fillText(tipCol+","+tipRow,tipX+2,tipY+17); } Here is code and a Fiddle: http://jsfiddle.net/m1eri

Finding Coordinates on a Bufferred Image
If you have a 4 x 4 checkerboard that's 400 x 400, then each square is 100 x 100 pixels. When you construct a BufferedImage like this, you save a Rectangle for each square as you're doing the construction. That way, when you do a mouse click later, you can use the contains method of Rectangle to determine which square was clicked. You shouldn't use absolute positioning. If your checker board takes up half the JPanel, FlowLayout or BoxLayout works well.

Assign WCS coordinates to a FITS image
I would advise you to start using astropy. For the purposes of your project the astropy.wcs package can help you write a FITS WCS header, and the astropy.io.fits API is basically identical to the pyfits one you are using now. Moreover the help pages are excellent, and all I'm about to do is translate their WCS building page to match your example. To your question: FITS does not "tag" each pixel with a coordinate. I suppose it is possible to create a pixel lookup table or something like that, but the actual WCS is an algorithmic translation of X,Y pixels to astrometric coordinates (in your case "Galactic"). A nice page is here. The example I would point you to is here: http://docs.astropy.org/en/latest/wcs/index.html#building-a-wcs-structure-programmatically And here is my untested pseu

Translating selection coordinates from a downscaled image
May be i am missunderstanding, but i think you are calculating "proportion" not "scale". The scale is product of the original dimentions with the new ones. May be: $scale_y = $original_height / $croptool_height; $scale_x = $original_width / $croptool_width; $scaled_x1 = $x1 * $scale_x; $scaled_y1 = $y1 * $scale_y; $scaled_x2 = $x2 * $scale_x; $scaled_y2 = $y2 * $scale_y; //Original height = 1000 and Croptool height = 100 ==> scale_y = 10; Pixel (0, 45) on crop space == 45 * 10 == 450 on original image. //Original height = 100 and Croptool height = 1000 ==> scale_y = 0.10; Pixel (0, 450) on crop space == 450 * 0.10 == 45 on original image.

Using scatterplot.density with x-y coordinates causes error in image.default
What I've found is that if the argument num.bins is high enough to seperate each point into a single bin then you will recieve the error. Try scatterplot.density(x, y, num.bins=11) vs. scatterplot.density(x, y, num.bins=10) the default is 64. That means 64 bins in the x axis and y axis. You either need to be lower you're bin number, add more points, or be content with the error. Hope that helps.

Coordinates-based text display upon an image with Django's template system
I ended up using the PIL library.
