  • I want to be able to save a customized color scheme in Vista

    - by Mel
    I know how to change my color scheme in Vista. What I despair about is that after I change it, if I switch to another scheme (such as back to Aero), my customized scheme is gone. If I want, I can take another 30 minutes to customize it so it doesn't burn out my eyes. Is there any way to save this scheme? I tried doing the color scheme change, then trying to save the whole thing as a theme, all to no avail.

  • iPhone: How to Determine Average Light/Dark of an Area of an UIImage

    - by TechZen
    I need to place labels with a transparent background over a variable-content UIImage. Readability will vary significantly depending on the relationship between the color of the label's text and the color/luminosity of the area of the image displayed under the label. Since the image will be constantly changing, the color of the label's text needs to change in sync. I have found several techniques for determining the color, perceived luminosity etc of a single pixel. However, I need to rather quickly (while a view loads) determine the rough perceived color/luminosity of an area of the UIImage under the frame of the UILabel. I presume I will also need to measure the alpha because the same color/luminosity looks different at different alpha values. Is there a way to calculate such a value for an area? Will I be reduced to simply summing pixels? If it comes to that, is there an algorithm to accomplish this? I've thought of two possible approaches: Perform some "folding" operations i.e. combining pixels from one half of the area to the other half. Then repeat until I get a single value. Would this be practical? How would you logically combine pixels to average their perceived color/luminosity? Sample a statistically significant number of pixels in the area and then combine them (somehow) to get a rough measure. I think this problem comes up a lot these days with people being so found of customizing backgrounds. Seems like something that would be worth my time to bang out a category or class to handle this and then share it around.

  • How to disable horizontal scrolling within virtualbox on Ubuntu guest, Windows 7 host?

    - by Steven Rosato
    I am using Windows 7 as Host, Ubuntu Karmic as guest OS with guest tools installed and I get an annoying glitch when switching from host to the guest machine: Vertical scrolling switches to horizontal! (using the mouse wheel). Since I don't really care about horizontal scrolling, how can I disable this? I have checked the web and the only thing I found was to play in the xorg.conf file and adding in the section "InputDevice" Option "ZAxisMapping" "4 5" which would enable vertical scrolling only. The thing is, I don't have that section in my config file so I guessed that I would need to add Section "InputDevice" Identifier "VBoxMouse" Driver "vboxmouse" Option "ZAxisMapping" "4 5" EndSection But that does not seem to work after restarting xserver. Any workaround for this?

  • Scrolling mouse sets windows sound volume

    - by Ikke
    Suddenly, when I use the scroll wheel of my mouse, it changes the windows sound volume level. I have a HP DV6-2030SD laptop with Windows 7 64 bit and a Zolid p50622 mouse. When I use the scroll function of the mouse pad of the laptop, it does not adjust the sound level. I don't have any special mouse drivers installed, just the standard windows drivers. When I scroll, I see the HP sound level screen: It doesn't do it always, but when it does, it prevents the current window to scroll, which is really annoying. Rebooting doesn't help. I've tried to put the USB dongle in a different port, but this doesn't help either. Any advise on how I can fix this?

  • How to find the average color of an image.

    - by Edward Boyle
    Years ago I was the lead developer of a large Scrapbook Web Site. One of the things I implemented was to allow shoppers to find Scrapbook papers and embellishments of like colors (“more like this color”). Below is the base algorithm I wrote to extract the color from an image. It worked out pretty well. I took the returned values and stored them in an associated table for the products. Yet another algorithm was used to SELECT near matches. This algorithm has turned out to be very handy for me. I have used it for borders and subtle outlined text overlays. I am sure you will find more creative uses for it. Enjoy… private Color GetColor(Bitmap bmp) { int r = 0; int g = 0; int b = 0; Color mColor = System.Drawing.Color.White; for (int i = 1; i < bmp.Width; i++) { for (int x = 1; x < bmp.Height; x++) { mColor = bmp.GetPixel(i, x); r += mColor.R; g += mColor.G; b += mColor.B; } } r = (r / (bmp.Height * bmp.Width)); g = (g / (bmp.Height * bmp.Width)); b = (b / (bmp.Height * bmp.Width)); return System.Drawing.Color.FromArgb(r, g, b); } You could also get the RGB values by passing in the RGB by ref private Color GetColor(ref int r, ref int g, ref int b, Bitmap bmp) but that is a bit much as you can simply get it from the return value: mReturnedColor.R; mReturnedColor.G; mReturnedColor.B;

  • pagination with css

    - by bsandrabr
    Hi I've tried every combination I can think of but I can't get this to work. Can you help? I'm trying to put some css onto my pagination and have read all the examples but they all contain so many backslashes and concatenation that I just dont know how to apply it Here is my pagination code (which works fine) along with my feeble attempt at styling it if ($st > 0) { $st3=$st; print "< Previous Page "; } $f=$st+3; for($i2=$st+1;$i2<=$f;$i2++) { $i3=$i2-3; if ($i3 0) { print "$i3 "; if($i2 % 3 == 0) { print ""; } } } $g=$st+3; for($i=$st+1;$i<=$g;$i++) { print "$i "; if($i % 3 == 0) { print ""; } } $st2=$st+2; print " Next Page "; Here is the css that I took from the website /* CSS Document */ body { background: #2D2D2D; font-family:Verdana, fantasy; font-size:13px; color: white; scrollbar-base-color: black; scrollbar-arrow-color: red; scrollbar-DarkShadow-Color: black; } a:visited,a:active,a:link { color: white;text-decoration: none; } a:hover { color: red;text-decoration: overline underline;background: none; } table,tr,td { font-family:Palatino Linotype; color: #FFFFFF;font-size: 12px; } .button { font-family:Verdana, fantasy; font-size:13; color:#FFFFFF; background-color: red; } input,textarea,dropdown{ font-family:Verdana, fantasy; font-size:13; color: #FFFFFF; background-color: #000000; border: 1px solid; } textarea,.submit input{ font-family:Verdana, fantasy; font-size:13; color:#ffffff; background-color: black; } .table { background-color:#000000; } .table3 { background-color:#000000; } .table td { color: #000000; background-color:#DEDEDE; height:22px; } .table3 td { background-color:#CCCCCC; } td .alt { background-color:#EEEEEE; height:22px; } td .h { background-image:url(tablehgrad.png); background-repeat:repeat-x; font-weight: bold; background-color: #D6D6D6; } .table th { background-image:url(tablehgrad.png); background-repeat:repeat-x; color: #000000; font-weight: bold; background-color: #D6D6D6; } .menu th { font-font-size: 12px; color: silver; background-image:url(th.png); background-repeat:repeat-x; font-weight: bold; background-color: #4B4B4B; } .stats td { font-font-size: 12px; color: white; font-weight: bold; } .menu td { font-size: 12px; text-align: center; color: white; background-image:url(tdover.png); background-repeat:repeat-x; font-weight: bold; background-color: #4B4B4B; } .menu td:hover{ color: white; background-image:url(td.png); div.pagination { padding: 3px; margin: 3px; } div.pagination a { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #AAAADD; text-decoration: none; /* no underline */ color: #000099; } div.pagination a:hover, div.pagination a:active { border: 1px solid #000099; color: #000; } div.pagination span.current { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #000099; font-weight: bold; background-color: #000099; color: #FFF; } div.pagination span.disabled { padding: 2px 5px 2px 5px; margin: 2px; border: 1px solid #EEE; color: #DDD; } thanks

  • Color Printer: Laser vs Inkjet

    - by Mike
    I am about to buy a color printer. I had a B&W Laserjet printer in the past but since then I've used inkjets for decades. I need a printer that can deliver high quality as these photo inkjet printers, but I'm tired of paying for ink that costs $9,000 per gallon (1 gallon = 3.785 liters = 300 cartridges = $9,000). So, I was thinking about buying a color laser printer, but I'm not sure these printers can deliver the same quality and are worth the investment in terms of toner consumption. I remembered that my old Laserjet printer was able to print 1100 pages per toner cartridge. The inkjet printers I have can print 500 pages per cartridge. Price by price, 2 inkjet cartridges have more or less the same cost as one toner cartridge and in theory prints almost the same. I am not sure if this is true for color lasers. What can you guys tell me about quality, toner cost and cost per page for laser or inkjet printer? Is it worth the change? (Keep in mind that an inkjet printer costs $50 and a laser printer costs $200.) Thanks.

  • Can someone explain this color wheel code to me?

    - by user1869438
    I just started doing java and i need some help with understanding this code. I got it from a this website. This is supposed to be code for a color wheel but i don't really understand how it works, especially the final ints STEPS and SLICES. import java.awt.Color; import objectdraw.*; public class ColorWheel extends WindowController { private double brightness; private Text text; private FilledRect swatch; private Location center; private int size; private FilledRect brightnessOverlay; private static final int SLICES = 96; private static final int STEPS = 16; public void begin() { canvas.setBackground(Color.BLACK); brightness = 1.; size = Math.min(canvas.getWidth(), canvas.getHeight() - 20); center = new Location(canvas.getWidth() / 2, size / 2); for(int j = STEPS; j >= 1; j--) { int arcSize = size * j / STEPS; int x = center.getX() - arcSize / 2; int y = center.getY() - arcSize / 2; for(int i = 0; i < SLICES; i++) { Color c = Color.getHSBColor((float)i / SLICES, (float)j / STEPS, (float)brightness); new FilledArc(x, y, arcSize, arcSize, i * 360. / SLICES, 360. / SLICES + .5, c, canvas); } } swatch = new FilledRect(0, canvas.getHeight() - 20, canvas.getWidth(), 20, Color.BLACK, canvas); brightnessOverlay = new FilledRect(0, 0, canvas.getWidth(), canvas.getHeight() - 20, new Color(0, 0, 0, 0), canvas); text = new Text("", canvas.getWidth() / 2, canvas.getHeight() - 18, canvas); text.setAlignment(Text.CENTER, Text.TOP); text.setBold(true); } public void onMouseDrag(Location point) { brightness = (canvas.getHeight() - point.getY()) / (double)(canvas.getHeight()); if(brightness < 0) { brightness = 0; } else if(brightness > 1) { brightness = 1; } if(brightness < .5) { text.setColor(Color.WHITE); } else { text.setColor(Color.BLACK); } brightnessOverlay.setColor(new Color(0f, 0f, 0f, (float)(1 - brightness))); } public void onMouseMove(Location point) { double saturation = 2 * center.distanceTo(point) / size; if(saturation > 1) { text.setText(""); swatch.setColor(Color.BLACK); return; } double hue = -Math.atan2(point.getY() - center.getY(), point.getX() - center.getX()) / (2 * Math.PI); if(hue < 0) { hue += 1; } swatch.setColor(Color.getHSBColor((float)hue, (float)saturation, (float)brightness)); text.setText("Color.getHSBColor(" + Text.formatDecimal(hue, 2) + "f, " + Text.formatDecimal(saturation, 2) + "f, " + Text.formatDecimal(brightness, 2) + "f)"); } }

  • WPF Binding to change fill color of ellipse

    - by user294382
    Probably a simple question but: How do I programmatically change the color of an ellipse that is defined in XAML based on a variable? Everything I've read on binding is based on collections and lists -can't I set it simply (and literally) based on the value of a string variable? string color = "red" color = "#FF0000"

  • UITableViewCell with custom gradient background, with another gradient as highlight color

    - by Rich
    I have a custom UITableViewCell with a custom layout. I wanted a gradient background, so in my UITableViewDelegate cellForRowAtIndexPath: method, I create a CAGradientLayer and add it to the cell's layer with insertSubLayer:atIndex: (using index 0). This works just fine except for two things: Most importantly, I can't figure out how to change to a different gradient color when the row is highlighted. I have tried a couple things, but I'm just not familiar enough with the framework to get it working. Where would be the ideal place to put that code, inside the table delegate or the cell itself? Also, there's a 1px white space in between each cell in the table. I have a background color on the main view, a background color on the table, and a background color on the cell. Is there some kind of padding or spacer by default in a UITableView?

  • Silverlight 4 Setting background color of textbox on focus

    - by Sean Riedel
    I am trying to set the background color of a Textbox to white on focus using a Style. My enabled Textbox has a Linear Gradient background by default: <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="#e8e8e8" Offset="0.0" /> <GradientStop Color="#f3f3f3" Offset="0.25" /> <GradientStop Color="#f4f4f4" Offset="0.75" /> <GradientStop Color="#f4f4f4" Offset="1.0" /> </LinearGradientBrush> </Setter.Value> </Setter> I have a focus visual state defined: <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"> <Storyboard> <DoubleAnimation Storyboard.TargetName="FocusVisualElement" Storyboard.TargetProperty="Opacity" To="1" Duration="0"/> </Storyboard> </VisualState> Here is the rest of the Control Template: <Border x:Name="Border" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="1" Opacity="1" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}"> <Grid> <Border x:Name="ReadOnlyVisualElement" Opacity="0" Background="#5EC9C9C9"/> <Border x:Name="MouseOverBorder" BorderThickness="1" BorderBrush="Transparent"> <ScrollViewer x:Name="ContentElement" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/> </Border> </Grid> </Border> <Border x:Name="DisabledVisualElement" Background="#A5D7D7D7" BorderBrush="#A5D7D7D7" BorderThickness="{TemplateBinding BorderThickness}" Opacity="0" IsHitTestVisible="False"/> <Border x:Name="FocusVisualElement" Background="#A5ffffff" BorderBrush="#FF72c1ec" BorderThickness="{TemplateBinding BorderThickness}" Margin="1" Opacity="0" IsHitTestVisible="False"/> On the last Border tag is where I am trying to set the background to white (#ffffff). Right now I have the opacity at A5 which does turn the background white, however it also starts to obscure the text in the box. Any higher opacity makes the text invisible so I am pretty sure that setting the background of that border is not the right way to do this. Can I set the Background color of the ContentElement somehow through a StoryBoard? Thanks.

  • Qt: Background color on QStandardItem using StyleSheet

    - by Johan
    Hi I have a class that inherits QStandardItem and I put the elements in a QTreeWidget. The class receive notifications from the outside and I want to change the background color of the item based on what happened. If I do not use stylesheets it works just fine, like this: void myClass::onExternalEvent() { setBackground(0, QColor(255,0,0))); } However as soon as I put a stylesheet on the QTreeWidget this has no effect, the stylesheet seems to override the setBackground call. So I tried : void myClass::onExternalEvent() { this-setStyleSheet("background-color: red"); } but this is probably all wrong, it changed the color of some other element on my screen, not sure why. So anyone have an idea on how I can alter the background color like with setBackgroundColor but still be able to use stylesheet on my QTreeWidget?

  • Use jQuery to find div by background color

    - by maxsilver
    I'm trying to use jQuery to find the number of divs that are both visible, and have a background color of Green. (Normally I'd just add a class to the div, style it green, and check for that class in jQuery but in this instance, I can't actually change the markup of the page itself in any way) I currently have the visible div part working as : if( // if there are more than one visible div $('div.progressContainer:visible').length > 0 ){ I'd like to throw some kind of "and background color is green" selector in there. // not legit javascript if( // if there are more than one visible div, and its color is green $('div.progressContainer:visible[background-color:green]').length > 0 ){ Is it possible to do this?

  • Calculating the average color between two colors in PHP, using an index number as reference value

    - by Roel Krottje
    Hi all! In PHP, I am trying to calculate the average color (in hex) between to different hex colors.. However, I also need to be able to supply an index number between 0.0 and 1.0. So for example: I have $color1 = "#ffffff" and $color2 = "#0066CC" .. If I would write a function to get the average color and I would supply 0.0 as the index number, the function would need to return "#ffffff". If I would supply 1.0 as the index number, the function would need to return "#0066CC".. However if I would supply 0.2, the function would need to return an average color between the two colors, but still closer to color1 than to color2.. If I would supply index number 0.5, I would get the exact average color of both colors.. I have been trying to accomplish this for several days now but I can't seem to figure it out..! Any help would therefor be greatly appreciated!.. Thanks!

  • HTML <select> selected option background-color CSS style

In the style I expected something like "selected-color", but it doesn't exist.

  • Graph coloring Algorithm

    - by Amitd
    From wiki In its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color; this is called a vertex coloring. Similarly, an edge coloring assigns a color to each edge so that no two adjacent edges share the same color, and a face coloring of a planar graph assigns a color to each face or region so that no two faces that share a boundary have the same color. Given 'n' colors and m vertices, how easily can a graph coloring algorithm be implemented? Lan

  • over Windows terminal change cursor width or color in Vim depending on mode

    - by INTPnerd
    I am using PuTTY to connect over SSH to an Ubuntu server from my Windows 7 workstation. Once connected I am using the Vim installation from the Ubuntu server to edit files. I want the cursor to change when I go into and out of insert mode. Part of my .vimrc file is like this but it is not changing the cursor: if &term =~ "xterm" echo "xTerm!!inate!" let &t_SI = "\<Esc>]12;purple\x7" let &t_EI = "\<Esc>]12;blue\x7" endif I know that the if statement is executing because of the echo. EDIT: Actually I would prefer to change the cursor to be a vertical line like you can in the PuTTY settings rather than change the color, or maybe even do both. But just changing the color would be a lot better than nothing. Also I am willing to change terminals if there is another Windows 7 Professionsal 64 bit compatible terminal that can do this (preferably something free). Maybe Poderosa can do this?
