  • IE 8 specifying background-color changes element behavior

    - by Mateo
    I have an absolutely positioned div on which I am trying to trigger mouseenter and mouseleave events. In IE8/7 with the background-color of the div left unspecified (so that it defaults to transparent), the mouseenter/leave events are not firing when the cursor crosses the div's boundary, only somewhere in the middle of the div and when the cursor is over any text within the div. When I attempt to debug the problem by adding a background color to the div (e.g. background-color: green), the problem magically goes away. The div's box model is honored perfectly and mouseenter/leave fire as when expected. It's only when the div's background color is left unspecified (or even explicitly set to transparent) that it doesn't behave correctly. Any ideas? Googling for this IE bug/quirk is coming up with nothing.

  • Xen P2V for large physical hosts with much free space

    - by Sirex
    I need to P2V a rhel5 machine to xen under rhel5. I know I can use dd if=/dev/sda then using virt-install --import on the host, but the downside of this is the original machine has 80% free space on its drive. Does anyone know of (or can document) a quick and easy method which works reliably, to produce a bootable xen image which can run under a hvm in such cases ? I tried clonezilla to make the image, to avoid the free space problem, but it failed to do the clone with "something went wrong" (useless info, i know). At the moment im looking at doing a dd of each partition, and a file level copy of the partition which is mostly empty, then creating a new virtual disk, copying the partitions over to it by mounting both the new image and the virtual drive on a second vm, then copying the boot sectors over, then copying the file level backup..... there must be an easier way ? Oh, and budget is $0. :)

  • Windows 8 Color Settings (Window Title)

    - by xixixao
    In Windows 7, the window title's color (by default black, to see the title in the title bar fire up Windows Media Player for example) is stored in [HKEY_CURRENT_USER\Control Panel\Desktop\Colors] TitleText value. This is not the case in Windows 8, since this value is only used when using high contrast theme. It looks like noone has come up with a way to change this color yet, so my question is, where to look? What tools can I use to see dependencies, what could be the way to find this value (I rightfully hope it's not a constant in code).

  • how many color combinations in a 24 bit image

    - by numerical25
    I am reading a book and I am not sure if its a mistake or I am misunderstanding the quote. It reads... Nowadays every PC you can buy has hardware that can render images with at least 16.7 million individual colors. Rather than have an array with thousands of color entries, the images instead contain explicit color values for each pixel. A 24-bit display, of course, uses 24 bits, or 3 bytes per pixel, for color information. This gives 1 byte, or 256 distinct values each, for red, green, and blue. This is generally called true color, because 256^3 (16.7 million) He says 1 byte is equal to 256 distinct values. 1 byte = 8 bits. 8^2 bits = 64 distinct colors right ?? It's not adding up right to me. I know it might be something simple to understand, but I don't understand.

  • Mac webcam photo application with access to camera settings (resolution, camera selection, color balance, focus)

    - by Pascal T.
    Does anyone know about a webcam photo application (ie an alternative to photo booth) with would allow to change the settings on the camera, such as : Select camera (I.e I want to use an external webcam) Change camera resolution (with photobooth change camera settings (I.e autofocus, aperture, color balance, etc..) I did a lot of research on the internet with no success. I am looking for a very simple app (such as wmcap.exe on Windows) What I tried so far: photo booth: it works with an external camera, however there is no way to change the resolution, or the color/focus settings manycam : a virtual webcam driver. you can add special effects to your camera and transfer those effects to any app, but not change your camera settings... iGlasses : enables you to change the camera settings inside photo booth and other apps. However you cannot control the focus, nor the video resolution macam (did not work on my Mac book Pro) Does anyone know better than me? Note : my only solution now is to launch a virtual machine (with parallels desktop) and take the pictures from there!

  • Serializing System.Drawing.Color in .NET

    - by alankdkd
    Hi all, I've used the default .NET serialization for a class with a System.Drawing.Color member. The code is now in use by people, and I need to add an extra member to the class, but still deserialize older versions. So I tried the standard way of doing this: The ISerializable interface, using SerializationInfo methods to get the int and string members. The problem: My class also has a System.Drawing.Color member, but SerializationInfo doesn't provide a "GetColor" method read this data type. I've tried getting it as an int and as a string, and casting it to System.Drawing.Color, but no luck. Does anyone know how to deserialize a System.Drawing.Color from SerializationInfo? Thanx! Alan

  • Video driver reports 8-bit color depth after Windows Update

    - by user3163
    Windows Update pushed out a new video driver for the Mobile Intel(R) 4 Series Express Chipset Family. One HP 6730b laptop was updated from 8.15.10.1872 to 8.15.10.2021. After the update the color depth is reported as 8-bit even if the setting is 32-bit. This means that Areo effects are disabled. Downgrading to 8.15.10.1872 did not help. Is there any way to force the video driver to report 32-bit color depth?

  • Degrafa color changer

I replaced fill="{bluedream}" with fill="using_variable" and lead to error compiled message: Initializer for 'fill': values of type com.degrafa.core.IGraphicsFill cannot be represented in text. Is there a solution to use this code as a color changer?

  • Multimap Space Issue: Guava

    - by Arpssss
    In my Java code, I am using Guavas Multimap (com.google.common.collect.Multimap) by using this: Multimap< Integer, Integer Index = HashMultimap.create() Here, Multimap key is some portion of URL and value is another portion of URL (converted into integer). Now, I assign my JVM 2560 Mb (2.5 GB) heap space (by using Xmx and Xms). However, it can only store 9 millions of such (key,value) pairs of integers (approx 10 million). But, theoretically (according to memory occupied by int) it should store more. Can anybody help me, 1) Why is this happening (means Multimap is taking lots of space) ? I checked my code with out inserting pairs in Multimap, it takes only 1/2 MB space. 2) Is there any other way or home-baked solution to solve this space issue ? More clearly, how to solve this memory issue ? Thanks in advance and any idea is perfectly OK for me.

  • Cannot open a .tif with color using .Net Image or Bitmap classes

    - by Tom Regan
    I am attempting to open .tif files that have color in them (300 dpi, PixelFormat.Format24bppRgb) using the .Net Image and Bitmap classes. I always get an "invalid parameter" error when the tiffs have color (works fine for black and white tiffs). If anyone has source code on how to open a .tif with color in it I'd deeply appreciate it. Below is what I'm attempting to do; this also fails when calling Bitmap.FromStream: using (FileStream fs = File.OpenRead(fileName)) { using (Image img = Image.FromStream(fs)) {} }

  • Change CkEditor's background color with jQuery methods

    - by user198003
    I need to change background color of CkEditor, on some basic jQuery methods, like ready, change, etc. Tried with things like: $(document).on('click','.change-task-status', function(e){ $(".cke_editable").css("background-color", 'red'); }) ... but nothing happens. Can you help me how to achieve this? Thank you in advance! PS. yes, I do have jQuery adapter loaded on page.

  • How do I determine darker or lighter color variant of a given color?

    - by Nidonocu
    Given a source color of any hue by the system or user, I'd like a simple algorithm I can use to work out a lighter or darker variants of the selected color. Similar to effects used on Windows Live Messenger for styling the user interface. Language is C# with .net 3.5. Responding to comment: Color format is (Alpha)RGB. With values as bytes or floats. Marking answer: For the context of my use (a few simple UI effects), the answer I'm marking as accepted is actually the most simple for this context. However, I've given up votes to the more complex and accurate answers too. Anyone doing more advanced color operations and finding this thread in future should definitely check those out. Thanks SO. :)
