Image Locator Feature

(1/4) > >>

John Donovan:
We've added a new "image locator" feature to PictureSnapApp which we think is pretty cool.

It allows one to load a stage calibrated image into PictureSnapApp and display its location on another image, say a map of your sample holder like this:



One can click an image in the image list to display it (or check the display all checkbox to display all the images). And one can double-click the image in the list to move the instrument stage to the center of the displayed image.

In addition, using the the mouse wheel one can zoom in on the selected image for a better view and then click/drag the zoomed image to move it around as seen here:

John Donovan:
I should also point out that when one moves these PSA images to another instrument, the stage units and orientations are automatically converted (the files are appropriately renamed), and after one recalibrates the main image, all annotations and (sub) images are automatically calibrated to the new instrument stage.

The idea being that by using PictureSnapApp one can easily move one's folder of images to another instrument, re-calibrate the main image and be navigating your sample on the new instrument in minutes.

John Donovan:
I realized last night that I had forgotten to save the current screen DPI for modified sub images in their corresponding ACQ files, so that is now fixed.   This only matters if one moves a set of images from one computer to another and they have different DPI values for the screens.

If you downloaded or updated PictureSnapApp in the last few days, please update again.  Sorry and thanks.

John Donovan:
I also wanted to show what happens when one moves their PictureSnapApp image files from one instrument to another.

In this case I moved images I acquired on the Cameca SX100 on a thin section sample, to our FEI Quanta and the software automatically transformed the stage coordinates from um to mm (the stages on both instruments are cartesian, so no need to transform the stage orientation), as seen here:



Once the images are on the new instrument, we simply re-calibrate the two (or three) calibration points using the SEM imaging/stage system and we can now accurately navigate to the areas of interest previously located on the EPMA (or visa versa!).

John Donovan:
Here's another example of the Image Locator feature showing multiple imported images displayed:



One can also display just the image outlines so one can see "underneath" them:
