PIL Question: Inverse of <image>.load( )?

I'm doing some image processing that requires accessing the individual
pixels of the image. I'm using PIL 1.1.6 and creating a 2D array of
pixel RGB tuples using the Image class instance load() method.
Unfortunately, I can't seem to find a reciprocal function that
converts the 2D array of RGB tuples back to an image. I've gone
through all of the online documentation and can't seem to find what
should be an obvious solution.

Any thoughts?

load returns an access object that's attached to the image; to modify
the image, just assign to the object:

pix = im.load()

v = pix[x, y]
pix[x, y] = v

to do bulk loads, you can use the getdata/putdata methods instead.

Ah - I didn't realize from the docs that the results of load() is an
in situ edit to the original buffer. Thanks!

I want to be able to programatically click on the center of an <INPUT type=image ...> element (I only care about IE 5.5+). This should work regardless of whether IE has focus. Normally you would do myDomElement.click and the mouse doesn't matter, but in the case of an input image element, what happens is the submitted url has something like "?x=12&y=7" appended to it (the numbers vary per mouse position on the clicked element). If you hit...

When I click on the image form element <INPUT type=image name=point src="map.png"> point.x and point.y values get submitted to the server specifying where on the image I have clicked. Is there any (simple) way to get ahold of that point.x and point.y BEFORE they are sent to the server (and prevent that from happening)? Ie. I just want the points where someone clicks on an image and not interested in a submission to the server.

Hi, today i found out some browsers (at least Mozilla and IE) support the <image> tag, its usage seems to be the same as for the <img> tag (IMDB.com uses it for example).

I found some old reference that this tag at least already existed in...

Hello, Does anyone know of a way to handle broken href image tags either by using the html img tag or the asp:image server control? For example, if my src attribute is broken, I would like to display an alternate image, ie one that blends in with the background instead of the standard eye sore x. I would imagine I could use the <asp:image> server controls events to check the src and then change it if it is broken, i am just not clear...

I have HTML web page with <asp:Image id=img_L runat=server ImageAlign=Top Visible=True Width=y Height=x></asp:Image>. For some images, less than 128K I can view image. Other image files > 128K, image is not viewable - comes up with X in picture box. Is there size restriction. How can I remove this - or how can I show images > 128K in web page. NOTE: x & y in asp:Image spec are distinct values - say 128 x 128 or 64 x 64 image sizes

Hello! I'm taking a file name from a database and using the <asp:imagetag in GridView to show the image.
