  • How To Adjust Properly Brightness And Contrast On Monitor

    - by Johannes
    This days, it seems that I either go worse with my eyes or some settings with contrast and brightness have been changed. However, I have been searching now for some tutorial on how to adjust contrast and brightness, and I have found already some, on how to use Microsoft Win7 Calibrate Display Color program, but some people don't recommend it.. My monitor control menu shows settings (which are by default) that contrast is set to 80, contrast to 90 and sharpnes to 45, for which I belive are pretty dam high. I'm usually every day in front of my PC about 6-10h. The biggest problem is, when the night comes, and I have to read some word document, after a 10-15m of reading, eyes starts hurting. I'm using ASUS VW198 and Nvidia 9800 GT graphic card. So please suggest me, what should I decrease, contrast or brightness or both?

  • How to increase contrast of Windows 7 Menu Item highlight

    - by Barry Kelly
    The Windows 7 menu item highlight effect is quite subtle - on my machine, menu items go from light grey to having a light blue shading. This makes it quite hard to tell at a glance which exact menu item is highlighted at any one time. You can see an example (from Firefox) here: Is there an easy way to increase the contrast of the menu item highlight effect, without having to go all-out to an over the top high-contrast color scheme?

  • looking for dark, high contrast theme

    - by d3pd
    I am looking for a dark, contrast theme. Most dark, high-contrast themes I have tried do not give sufficient contrast to many edges, such as the edges of buttons, tabs, windows and other borders. Could you recommend themes that would provide such features? Alternatively, could you recommend a guide to changing a fairly dark theme, such as Numix-Cyanogen, such that it would feature light button, tab, window and other borders? Roughly visually, what I mean is to from this: to something like this:

  • Change the contrast of Image like Adobe Photoshop in ASP.net C#

    - by Hoque
    While I was trying to change the brightness and contrast of Image using C#, but I could not get success in changing the contrast of the Image. May I expect any support from here. I am using ColorMatrix to do that. Here are the code that I am using for brightness(works fine) and contrast(does not work properly). public static ColorMatrix CreateBrightnessMatrix(float Brightness) { if (Brightness < -1 || Brightness > 1) throw new ArgumentOutOfRangeException("Brightness value is out of range"); ColorMatrix cm = new ColorMatrix(new float[][]{ new float[] { 1f, 0, 0, 0, 0}, new float[] { 0, 1f, 0, 0, 0}, new float[] { 0, 0, 1f, 0, 0}, new float[] { 0, 0, 0, 1f, 0}, new float[] {Brightness, Brightness, Brightness, 1f, 1f}}); return cm; } public static ColorMatrix CreateContrastMatrix(float Contrast) { if (Contrast < 0 || Contrast > 3) throw new ArgumentOutOfRangeException("Contrast value is out of range"); float Trans = (1f - Contrast) / 2f; ColorMatrix cm = new ColorMatrix(new float[][]{ new float[] {Contrast, 0f, 0f, 0f, 0f}, new float[] { 0f, Contrast, 0f, 0f, 0f}, new float[] { 0f, 0f, Contrast, 0f, 0f}, new float[] { 0f, 0f, 0f, 1f, 0f}, new float[] { Trans, Trans, Trans, 0f, 1f}}); return cm; } Thanks.

  • Hue, saturation, brightness, contrast effect in hlsl

    - by Vibhore Tanwer
    I am new to pixel shader, and I am trying to write a simple brightness, contrast, hue, saturation effect. I have written a shader for it but I doubt that my shader is not providing me correct result, Brightness, contrast, saturation is working fine, problem is with hue. if I apply hue between -1 to 1, it seems to be working fine, but to make things more sharp, I need to apply hue value between -180 and 180, like we can apply hue in Paint.NET. Here is my code. // Amount to shift the Hue, range 0 to 6 float Hue; float Brightness; float Contrast; float Saturation; float Alpha; sampler Samp : register(S0); // Converts the rgb value to hsv, where H's range is -1 to 5 float3 rgb_to_hsv(float3 RGB) { float r = RGB.x; float g = RGB.y; float b = RGB.z; float minChannel = min(r, min(g, b)); float maxChannel = max(r, max(g, b)); float h = 0; float s = 0; float v = maxChannel; float delta = maxChannel - minChannel; if (delta != 0) { s = delta / v; if (r == v) h = (g - b) / delta; else if (g == v) h = 2 + (b - r) / delta; else if (b == v) h = 4 + (r - g) / delta; } return float3(h, s, v); } float3 hsv_to_rgb(float3 HSV) { float3 RGB = HSV.z; float h = HSV.x; float s = HSV.y; float v = HSV.z; float i = floor(h); float f = h - i; float p = (1.0 - s); float q = (1.0 - s * f); float t = (1.0 - s * (1 - f)); if (i == 0) { RGB = float3(1, t, p); } else if (i == 1) { RGB = float3(q, 1, p); } else if (i == 2) { RGB = float3(p, 1, t); } else if (i == 3) { RGB = float3(p, q, 1); } else if (i == 4) { RGB = float3(t, p, 1); } else /* i == -1 */ { RGB = float3(1, p, q); } RGB *= v; return RGB; } float4 mainPS(float2 uv : TEXCOORD) : COLOR { float4 col = tex2D(Samp, uv); float3 hsv = rgb_to_hsv(col.xyz); hsv.x += Hue; // Put the hue back to the -1 to 5 range //if (hsv.x > 5) { hsv.x -= 6.0; } hsv = hsv_to_rgb(hsv); float4 newColor = float4(hsv,col.w); float4 colorWithBrightnessAndContrast = newColor; colorWithBrightnessAndContrast.rgb /= colorWithBrightnessAndContrast.a; colorWithBrightnessAndContrast.rgb = colorWithBrightnessAndContrast.rgb + Brightness; colorWithBrightnessAndContrast.rgb = ((colorWithBrightnessAndContrast.rgb - 0.5f) * max(Contrast + 1.0, 0)) + 0.5f; colorWithBrightnessAndContrast.rgb *= colorWithBrightnessAndContrast.a; float greyscale = dot(colorWithBrightnessAndContrast.rgb, float3(0.3, 0.59, 0.11)); colorWithBrightnessAndContrast.rgb = lerp(greyscale, colorWithBrightnessAndContrast.rgb, col.a * (Saturation + 1.0)); return colorWithBrightnessAndContrast; } technique TransformTexture { pass p0 { PixelShader = compile ps_2_0 mainPS(); } } Please If anyone can help me learning what am I doing wrong or any suggestions? Any help will be of great value. EDIT: Images of the effect at hue 180: On the left hand side, the effect I got with @teodron answer. On the right hand side, The effect Paint.NET gives and I'm trying to reproduce.

  • How do I detect if a display is in High Contrast mode?

    - by banjollity
    I'm testing my company's established Swing application for accessibility issues. With high contrast mode enabled on my PC certain parts of this application are rendered properly (white-on-black) and some incorrectly (black-on-white). The bits that are correct are the native components (JButton, JLabel and whatnot) and third party components from the likes of JIDE. The incorrect bits are custom components and renderers developed in-house without consideration for high-contrast mode. Clearly it's possible to detect when high-contrast mode is enabled. How do I do this?

  • High contrast theme Firefox problem

    - by user87239
    I am using the high contrast inverse theme in 12.04 as I am visually impaired. This generally works great but causes a problem in Firefox as entered text e.g into a Google search is white. As the text background is also white you cannot see what you are typing. I have read through a good thirty websites with similar issues but thus far nothing works. I have tried all the settings in Firefox like un-checking "Use System Defaults" as well as manually telling Firefox what colours to use and these setting have absolutely no effect on anything.

  • deactivate dynamic contrast on dell xps

    - by Rock
    I am experiencing annoying automatic backlight brightness changes under ubuntu 12.04 LTS on my Dell XPS ultrabook. It seems to be connected to the amount of white pixels on the screen (switching back an forth between dark/light application windows makes the effect noticable, but also just scrolling through a website.) So I think it is the dynamic contrast feature of the notebook screen. How do I turn this off in Ubuntu? Windows offers specific Intel driver options for this, but I can't find any for Ubuntu. EDIT: Model: Dell XPS 14 Ultrabook and currently running Unity

  • Adjust brightness and contrast?

    - by Anon58
    I have an acer aspire as5750. With the intel hd 3000 graphics. When i use the adjustment function keys the dial moves but it doesn't translate to the screen diming. Same with the dial in linux settings. Also in colour settings it seems there is no colour file or icc profile available for this laptop. Do you think if i can get a working icc profile then it will fix this or not? I have found something that could work:Argyll but it looks complicated to use, has anyone here used it? Would it allow me to dim? Or is there any other work around? I have searched lots but can't find a solution.

  • Configuring a monitor's contrast/brightess/colours/etc

    - by DMA57361
    I have recently bought myself a new monitor, now I'd had my previous screen well over 5 years now so I'm looking at this one thinking the picture doesn't quite look right (not bad, just different). Rather than just wait until I'm used to the new picture I'd rather get it fine tuned, then get used to it - so I can reap the maximum benefit. So, can you please suggest reliable ways of configuring an LCD monitor's brightness/contrast/colour/etc to provide the optimum possibly quality image?

  • Help with Pixel Shader effect for brightness and contrast

    - by Hans
    What is a simple pixel shader script effect to apply brightness and contrast? I found this one, but it doesn't seem to be correct: sampler2D input : register(s0); float brightness : register(c0); float contrast : register(c1); float4 main(float2 uv : TEXCOORD) : COLOR { float4 color = tex2D(input, uv); float4 result = color; result = color + brightness; result = result * (1.0+contrast)/1.0; return result; } thanks!

  • LCD problems: brightness / contrast blown out, can't bring up menu

    - by davr
    Yesterday, when I turned on my LCD monitor, the colors were very very bright. It looks as if someone had gone into the monitor on-screen-display and turned up brightness & contrast all the way to the max. Colors were washed out, and it's almost painful to look at. So I tried to go into the menu and see if the settings were wrong somehow...and I found that I cannot bring up the menu. All the buttons on the front of the monitor now do nothing, except the power button. I was able to go into my graphics card settings, and turn the brightness way down to compensate, so it's at least usable for now, but it's not quite right, there is definitely some loss of color resolution or something from the two extreme settings canceling each other out. Any ideas what kind of failure in the LCD might cause this? According to the control panel, the model number is: KL2490DW-D It's a 24" 1920x1200 with the brand "synaps".

  • Is there a way to adjust colors of a specific window?

    - by Synetech
    Is there a (Windows) program or something that will allow the user to adjust the brightness/contrast/gamma of a specific window rather than the whole screen? As a use-case scenario, imagine having a web-page showing on one half of the screen, and another program taking up the rest of the screen. This other program uses the default Windows colors (e.g., white background), so it may be glaringly bright. Alternately, the web-page may be too dark to see. Adjusting the monitor or video-card settings would affect everything which will be no good. Adjusting the default Windows colors is, at best, inconvenient. Instead, there needs to be a way to set the colors of one of the windows to equalize the whole screen.

  • Set the Image brightness and contrast using OpenGL ES.

    - by Viral
    hi friends, I want to set Image Brightness and contras of images that are in my photo library, I got the code from http://developer.apple.com/iphone/library/samplecode/GLImageProcessing/Introduction/Intro.html, but that will work on the EAGL layer i.e. all the effects are provided on image that is put initially not on the image that are selected from the photo library ,as this function will work on the view(EAGLview) and not on the image view. so how to change the brightness and contras of any images that are selected from the photo library?? if any one know this please let me know.. regards viral.

  • Git and Mercurial - Compare and Contrast

    - by TM
    For a while now I've been using subversion for my personal projects. More and more I keep hearing great things about Git and Mercurial, and DVCS in general. I'd like to give the whole DVCS thing a whirl, but I'm not too familiar with either option. What are some of the differences between Mercurial and Git? Note that I'm not trying to find out which one is "best" or even which one I should start with. I'm mainly looking for key areas where they are similar and where they are different, because I am interested to know how they differ in terms of implementation and philosophy.

  • Counting down to zero in contrast to counting up to length - 1

    - by Helper Method
    Is it recommended to count in small loops (where possible) down from length - 1 to zero instead of counting up to length - 1? 1.) Counting down for (int i = a.length - 1; i >= 0; i--) { if (a[i] == key) return i; } 2.) Counting up for (int i = 0; i < a.length; i++) { if (a[i] == key) return i; } The first one is slightly faster that the second one (because comparing to zero is faster) but is a little more error-prone in my opinion. Besides, the first one could maybe not be optimized by future improvements of the JVM. Any ideas on that?

  • How to remove contrast from recaptcha?

    I know the idea is to make the text somehow hard to read for the users but still they complain and I've seen how the control used here in stackoverflow doesn't have the dark circles contrasting with the text in recaptcha. How can I replicate this? Thanks.

  • Constructing colours for maximum contrast

    - by Martin
    I want to draw some items on screen, each item is in one of N sets. The number of sets changes all the time, so I need to calculate N different colours which are as different as possible (to make it easy to identify what is in which set). So, for example with N = 2 my results would be black and white. With three I guess I would get all red, all green, all blue. For all four, it's less obvious what the correct answer is, and this is where I'm having trouble.

  • Why do some programmers think there is a contrast between theory and practice?

    - by Giorgio
    Comparing software engineering with civil engineering, I was surprised to observe a different way of thinking: any civil engineer knows that if you want to build a small hut in the garden you can just get the materials and go build it whereas if you want to build a 10-storey house you need to do quite some maths to be sure that it won't fall apart. In contrast, speaking with some programmers or reading blogs or forums I often find a wide-spread opinion that can be formulated more or less as follows: theory and formal methods are for mathematicians / scientists while programming is more about getting things done. What is normally implied here is that programming is something very practical and that even though formal methods, mathematics, algorithm theory, clean / coherent programming languages, etc, may be interesting topics, they are often not needed if all one wants is to get things done. According to my experience, I would say that while you do not need much theory to put together a 100-line script (the hut), in order to develop a complex application (the 10-storey building) you need a structured design, well-defined methods, a good programming language, good text books where you can look up algorithms, etc. So IMO (the right amount of) theory is one of the tools for getting things done. So my question is why do some programmers think that there is a contrast between theory (formal methods) and practice (getting things done)? Is software engineering (building software) perceived by many as easy compared to, say, civil engineering (building houses)? Or are these two disciplines really different (apart from mission-critical software, software failure is much more acceptable than building failure)?

  • How to use JavaScript to measure how bright a users monitor is ?

    - by HankV
    I've noticed that the brightness of computer monitors drastically varies between computers. As such, this changes the look of web pages greatly. Is there a way to use JavaScript to automatically detect how bright (or dark) a users monitor is so that I can adjust my web page colors accordingly? UPDATE Please note that I do not want manual user involvement. I want this detection to be automatic so that users don't realize I dynamically change the color palette automatically based on the brightness/darkness of their monitor.

  • Combine Two Shader Program

    - by Siddharth
    For my android application, I want to apply brightness and contrast shader on same image. At present I am using gpuimage plugin. In that I found two separate program for brightness and contrast as per the following. Contrast shader: varying highp vec2 textureCoordinate; uniform sampler2D inputImageTexture; uniform lowp float contrast; void main() { lowp vec4 textureColor = texture2D(inputImageTexture, textureCoordinate); gl_FragColor = vec4(((textureColor.rgb - vec3(0.5)) * contrast + vec3(0.5)), textureColor.w); } Brightness shader: varying highp vec2 textureCoordinate; uniform sampler2D inputImageTexture; uniform lowp float brightness; void main() { lowp vec4 textureColor = texture2D(inputImageTexture, textureCoordinate); gl_FragColor = vec4((textureColor.rgb + vec3(brightness)), textureColor.w); } Now applying both of the effects I write following code varying highp vec2 textureCoordinate; uniform sampler2D inputImageTexture; varying highp vec2 textureCoordinate2; uniform sampler2D inputImageTexture2; uniform lowp float contrast; uniform lowp float brightness; void main() { lowp vec4 textureColorForContrast = texture2D(inputImageTexture, textureCoordinate); lowp vec4 contastVec4 = vec4(((textureColorForContrast.rgb - vec3(0.5)) * contrast + vec3(0.5)), textureColorForContrast.w); lowp vec4 textureColorForBrightness = texture2D(inputImageTexture2, textureCoordinate2); lowp vec4 brightnessVec4 = vec4((textureColorForBrightness.rgb + vec3(brightness)), textureColorForBrightness.w); gl_FragColor = contastVec4 + brightnessVec4; } Doesn't able to get desire result. I can't able to figure out what I have to do next? So please friends help me in this. What program I have to write?
