Hi,
I'm writing an app that downloads images. It rejects images that are
under a certain size - whithout downloading them completely. I've
implemented this using PIL, by downloading the first K and trying to
create a PIL image with it. PIL raises an exception because the file is
incomplete, but the image object is initialised with the image
dimensions, which is what I need. It actualy works well enough, but I'm
concerened about...

Hi all,
I'm in search of a fast solution to reading image dimensions. I know
you can get the image dimensions by loading a file into an image
object, and then reading the height/width properties, but this is
really slow (relatively speaking).
Another poster suggested I could read the image headers manually by
streaming the first X number of bytes of the file, but this is fairly
consuming approach and hoping there's another option.

I am rotating images at one location of my web site. My problem is if
I set the width and height of the new image before I show the new
image, the old image is stretched first to the new image dimensions,
and if I show the new image before setting its dimensions, the new
image is stretched first to the old image dimension before it is
adjusted to its own dimension.
I would like to load a new image with its own dimension at the same
time....

Hello,
I have an ole object field (Access XP/2002) which I store images in. I have
a couple of questions regarding this; is it possible to determine the image
dimensions? Secondly, is there any way to determine what application is
associated with the stored OLE Object and is there a way to associate that
object programmatically with another application?
Thanks!

Is there a way in javascript to find out the size of an image you've just
preloaded?
I have the following object:
function tourImage(imgName) {
// used for passing image details to a function.
this.name=imgName;
//this.imgLoadImg = document.getElementById("imgLoadImg");
function preload(callback) {

I am building a photo gallery using code which creates thumbnails of a specific size from any image. When clicked the thumbnail expands dynamically to a pre-determined size.
The sizes of the thumbnails and the enlarged image are set via variables. To work properly, all the original images must be the same dimensions which means a great deal of editing and cropping before the images can be posted. And portrait images sometimes cannot be cropped...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
