I've made a really basic drawing program in Python with Pygame. The program has a square window, in which you draw. How could I save the area inside the window as an image?
As downshift commented, use pygame.image.save
win = pygame.display.set_mode(...)
# your stuff
pygame.image.save(win, "screenshot.jpg")

How to locate JLabels to an absolute position on Java GUI
(3 answers)
Closed 7 years ago.
Is there any way to put JLabels one top on other? Trying to make a card hand representation in Netbeans. I am using JLabel icon for each card. Like you have 1st card (label) on top, then next one a bit right and down from the 1st card and etc. Netbeans form designer does not allow to make intersections of JLabels. Just put the label next to another one.
I found the solution in JLayeredPane

How to upload and store files in Cocoa with Core Data?
(3 answers)
Closed 8 years ago.
I am creating a custom NSValueTransformer subclass to save a file as a Transformable attribute in Core Data. I am using [NSData dataWithContentsOfURL:value]; to transform one way, but how do I get the file back?
This is an arbitrary file, so how can I determine what kind it is so I can display the images or open it with a proper application?
Thanks

Save the URL and/or mime type as we'll so you can examine it (the extension) later to decide what to do.

I am trying this feed http://servicios.elpais.com.uy/formatos/rss/index.asp?seccion=ultmom
throw the simplepie demo page and it works great.
I can get a lot of info of this feed, but I dont know how to get the images and if you try the demo it is possible.
How can I get this images?
PS: I dont mean the feed image, I mean each news image

Some versions of RSS/Atom have a thumbnail others don't. If you want to get images all images from a feed you'll need to use something like simple_html_dom.
This question gets asked all the time, someone who knows how StackOverflow and SimplePie work should merge these answers.
