  • What is the target color profile in Image.FromFile?

    - by Jan Zich
    I am curious what the useEmbeddedColorManagement parameter in System.Drawing.Image.FromFile actually does. This parameter directory corresponds to a GDI+ parameter in the same method of the same class. So debugging .NET source does not lead anywhere. If my understanding of color profiles is correct, a color profile is basically a mapping which describes how particular RGB triples (or CMYK or something else) map into the so called Profile Connection Space (CIELAB or CIEXYZ). Now, if I open an image with embedded color in .NET setting useEmbeddedColorManagement to true, my experience is I get an image whose RGB values are not exactly the same as the original values in the file, i.e. is transformed. Since the original image was an RGB and the new is also an RGB, there must have been a transformation from the embedded color profile to a Profile Connection Space and the back to RGB. The thing which I don’t understand is what is the target color system? Is it some default Windows color profile? Is the current monitor profile? Is it sRGB?

  • How do I make my page respect h1 css addition? [migrated]

    - by Adobe
    I add h1 { margin-top:100px; } to the end of the css, but the page doesn't change. But if I add to the html of some h1: <h1 style="margin-top:100px;"><a class="toc-backref" href="#id4">KHotKeys</a><a class="headerlink" href="#khotkeys" title="Permalink to this headline">¶</a></h1> Then it does. I'm not css pro, and I guess the problem is somewhere in the css file. Here it is: div.clearer { clear: both; } /* -- relbar ---------------------------------------------------------------- */ div.related { width: 100%; font-size: 90%; } div.related h3 { display: none; } div.related ul { margin: 0;

  • Find and free disk space that is unused but unavailable (due to file system error, etc.)

    - by Voyagerfan5761
    Sometimes I get the feeling that if an app such as μTorrent allocates files on my FAT32-formatted flash drive, but then is killed or crashes (as happens more than a few times a month), that space just disappears from my file system. Whether or not that is the case, sometimes I do get a chill from wondering if I've lost hundreds of MB in available storage due to carelessness or malfunctions. Checking my disk with WinDirStat just makes it worse, because I see the huge "<Unknown>" item at the disk root staring at me, eating up well over a gigabyte. It might be FS inefficiency (due to 32 or 64kb sector/cluster size and a lot of tiny files) or it might be a glitch... Is there a tool I can download and run to check my file system and make sure that there aren't any unused allocated blocks on the disk? I want to make sure I'm not losing any disk space to I/O errors, etc.

  • How can I free up some space in my C: drive?

    - by Faraaz
    Each time I try to save a file, I get a message from my computer (with Windows 7) that asks me to free up some space in my Drive C before being able to save my intended file. But the more I search for extraneous files to delete, the more I get frustrated. I simply can't find out what "extra" file(s) I have that are occupying about 20 gigs of my C drive. As far as I know I save all the downloadable stuff to my other drives, and the most part of what I do with my computer is just Internet browsing. Would you please help me find the file or files that have occupied so much space in my Drive C so that I can remove them?

  • How to change image to this color?

    - by askmoo
    I have this image And I need to change it to the color #D21108 (type of RED). Of course, I do not want to paint it to this color, but to change the color to #D21108 and its shades (like I do in Photoshop via Brush Colour Replacement). I have all info about this color, values of RGB, CMYK, Lab and HSV if you need them. Now, I guess I can easily change it via GIMP's menu "Colors". I tried options Color Balance, Hue-Saturation, Colorize, but I did not find a way to enter the starting color I need. I was closest to my aim via Hue-Saturation, but I could not get this red value, no matter what I tried. As I am not a graphics expert, please tell me how to accomplish this task. PS. What's the meaning of Lab and HSV in the color scheme? I know the meaning of RGB and CMYK.

  • Why can't I extend the C: drive on Vista? Because I have Free Space to its right instead of Unalloca

    - by tzup
    Okay this is annoying! I have a C: drive that is the primary partition (bootable) that I would like to extend. In order to do that it seems like I need to have Unallocated Space to the right of the partition. Right now, I have "Free Space" to the right. How in the world do I make it Unallocated (not formatted)? There must be some command line utility to be able to do this. Please help!

  • Reclaim Vertical UI Space by Moving Your Tabs to the Side in Firefox

    - by Asian Angel
    Are you looking for a way to move your tabs to the side in Firefox and gain access to more vertical UI space? The Vertical Tabs extension for Firefox lets you accomplish both in a matter of moments. As soon as you install the extension and restart Firefox the Tab Bar will be automatically converted into a shiny new Vertical Tabs Sidebar. All that you have to do is start enjoying the extra vertical UI space. Some things to keep in mind when using the extension are: You can easily adjust the width of the sidebar to suit your needs using the mouse (very nice!) The Firefox Menu Button, Panorama Button, and Tab Control controls move to the bottom of the sidebar (see screenshot above) You can group tabs if needed or desired There is no option available to move the sidebar to the right side of the browser at the moment The use of Personas themes (or other themes) may affect how the text for the tabs will look (i.e. a slightly fuzzy shadow effect when not selected as seen in the screenshot above) Note: Works with Firefox 4.0b7 – 4.0.* Install the Vertical Tabs Extension [Mozilla Add-ons] Latest Features How-To Geek ETC Should You Delete Windows 7 Service Pack Backup Files to Save Space?

  • "Failed to create swap space" error during installation

    - by Welsh Heron
    I've been trying to install Ubuntu for the past two days or so, but I've been running into a problem: every time I run the installation program on the LiveCD, I always get the same (or a very similar) error: "Failed to create Swap space The creation of swap space in partition #3 of SCSI5 (0,0,0)(sda) failed." So far, I've run DBAN (Darik's Boot and Nuke) on my HDD once, to make absolutely sure that everything on it had been erased. Then, I simply put in the LiveCD, and let it run the automated install. I get the above error directly after I tell it to automatically partition the HDD (it will work for a second or so, then this will pop up), forcing me back to the screen that lets me choose whether I want to automatically or manually partition the HDD. Well, after failing to install the software manually, I did a little research and learned enough about partitioning Linux to use the 'Manual partitioning' option. I partitioned the HDD as follows (it's a 1TB drive): /home - (the rest)- ext2, / - 20GB - ext2, /boot - 100MB - ext2, /swap - 8GB /EFIboot - 40MB The only difference when I tried this method was that I got THIS message: "Failed to create Swap space The creation of swap space in partition #2 of SCSI5 (0,0,0)(sda) failed." Basically, the only difference was that there was now a '2' instead of a '3'. If I may ask, what exactly am I doing wrong? I've tried looking around the internet (that's basically all I've done for the last two days), but no one seems to have the same problem that I have, and I've tried most of the solutions for similar problems (DBAN, formatting partitions in ext2 format, etc). The only thing I haven't tried is using the terminal to manually partition the HDD...and I actually DID try to do this, but I wasn't able to get past 'su' 's password demand, so I wasn't able to use the terminal. Thank you for your help in advance. ~Welsh

  • XNA C# How to draw fonts in different color

    - by XNA newbie
    I'm doing a simple chat system with XNA C#. It is a chatbox that contains 5 lines of chat typed by the users. Something like a MMORPG chatting system. [User1name] says: Hi [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. When the user pressed 'ENTER', the text he entered will be added inside an ArrayList chatList.Add(s); For displaying the text he entered, I used for (int i = 0; i < chatList.Count(); i++) { spriteBatch.DrawString(font, chatList[i], new Vector2(40, arr1[i]), Color.Yellow); } *arr1[i] contains 5 y-axis points to print my 5 line of chats in the chatbox Question1: What if I have another type of message which will be added into ChatList (something like a system message). I need the System Message to be printed out in red color. And if the user keeps on chatting, the chat box will be updated according: (MAX 5 LINES) The newest chat will be shown below, and the oldest one will be deleted if they reached the max 5 lines. [User2name] says: Hello [User1name] says: What are you doing? [User2name] says: I'm fine [System] The time is now 1:03AM. [User1name] says: Ok, great to hear that! I'm having trouble to print each line color according to their msg type. For normal msg, it should be yellow. For system msg, it should be red. Question2: And for the next problem, I need the chat texts to be white color, while the names of the user is yellow (like warcraft3 chat system). How do I do that? I have a hard time thinking of a solution for these to work. Advise needed.

  • Color sprite tint with opacity in MonoGame/XNA

    - by Piotr Walat
    In MonoGame I am using SpriteBatch to draw sprites. I want to create a semi transparent overlay that would 'tint' the sprite with a given color. SpriteBatch.Draw accepts Color parameter that allows to specify the tint, however the alpha channel seems to make the whole sprite transparent (not the tint only). To address the problem i am overlaying my sprites with another white, semitransparent sprite tinted to a given color. It works as expected, but I am not sure if that is the correct (ie. most optimal) approach. Can you suggest better/faster technique?

  • SpaceX’s Dragon Spacecraft Docks with the ISS [Video]

    - by Jason Fitzpatrick
    This weekend was the first time a commercial space craft successfully rendezvoused with the International Space Station. Check out this video to see the opening of the hatch. From the notes on NASA’s video release: Aboard the International Space Station, Expedition 31 Flight Engineer Don Pettit and Joe Acaba of NASA and European Space Agency Flight Engineer Andre Kuipers opened the hatch to SpaceX’s Dragon cargo craft and entered the vehicle May 26, one day after the world’s first commercial cargo spacecraft was berthed to the Earth-facing port of the Harmony module. Dragon will remain berthed to Harmony until May 31, enabling the crew to unload supplies for the station’s residents before it is re-grappled and released to return to Earth for a parachute-assisted splashdown in the Pacific Ocean off the coast of southern California.

    Most digital cameras have the ability to set the “color temperature” based on the condition, but what exactly does that mean? This simple cheat sheet highlights the differences between various lighting situations and what settings you should use. Courtesy of Digital Camera World, the above chart shows where on the scale various color temperatures fall, how the automatic white balance works, and which presets you should use if available.

  • Ubuntu Installation-Allocate drive space/Boot Loader

    - by user10134
    When I try to install ubuntu 10.10 from the official livedisc I got in the mail, when I get to the "Allocate Disk Space" step I cannot get it to work. I shrank my win7 partition so I have unallocated space, then I tried using the space while it is formatted in NTFS, but the partitions will not show up in the box. /dev/sda is selected under boot loader, and I can't select anything else, but the partition box is blank so when I click "install ubuntu" it just says: "No root file system is defined. Please correct this from the partitioning menu." -I am trying to dual-boot win7 and ubuntu, but I was never asked in the install process whether I would like to install just ubuntu or dual-boot?

  • Blank space on right side of screen with XMonad/Gnome

    - by Andrew
    Fresh install of 11.10 x64. I set up XMonad with gnome-session as I did before on 11.04, following the guide on the Arch wiki. Everything works, but there's this weird vertical space about the size of a scrollbar on the side of the screen. The space is also above xmobar (the battery system tray icon is hidden behind it and I can't click it). XMonad weird space (since I can't post images) Is there some weird XMonad or Gnome option I'm missing? I don't even know where to begin to look.

  • How to make the working environment of a programmer less shiny?

    - by Roflcoptr
    Last year I had a sport accident and since then my left eye is a little bit sensitive. Especially if looking in bright and shiny colors, I get tired very fast and can't literally focus on anything. White is the worst color ever! Unfortunately most application that I use in my work environment (Firefox, Eclipse, Visual Studio, Tetris) have a very bright white background. This really hurts my eye. So is there an easy way to generally use color schemes on the laptop so that everything isn't that bright? Obviously I could everywhere change the default color scheme, but isn't there a simpler solution to do that? Or any recommendations what are good color schemes to be less bright but still clearly readable?

  • Nicest way to map rgb colors from html to led

    - by back_ache
    I have attached an rgb led to a color picker on a webpage and have hit the obvious problem that though the led is 8-bit like html the color rendition is very different so with the more subtle shades the led values for the color are wildly different to the html values. The brute-force method would be for me to have a lookup-table on the webserver to map the two sets of values but would ideally like to do it more elegantly Before I start listing all my 101 ideas for doing this I wondered if anyone else had come across the issue, the end-game would be to be able to abstract the color-rendition of different leds and make it available as a webservice (html value and device id in, led value out)

  • LWJGL - OpenGL - Texture shading

    - by Trixmix
    I want to use LWJGL to create a shader that all it does is change the color of the given texture. For example I tell it to draw the letter A using a sprite sheet then I can tell the shader to draw the letter in a certain color. How would you do something like this without needed to create different colored letter sprite sheets? Task for the shader: Simply change all pixels to a certain color in the texture. Input: Color , texture. Output: it draws onto the screen the new colored texture. How do i accomplish such a thing?

  • Problems installing Ubuntu on unallocated space

    - by Adam
    I've been trying to install Ubuntu on some unallocated space, but I'm getting confused with the manual partition setup. I didn't want to try the other options for it suggested that everything on my drive would be erased (but I might be wrong) I have an old(ish) laptop with a 60GB hard-drive. Theres a Windows 7 partition of 30GB, followed by 20GB of unallocated space, then HP's Windows recovery partition of under 10GB. Do I need to format the empty space in windows first? What's the recommended method in this case?

  • Oh Unity Launcher scrambled with color dots after log on or restart

    - by Cominatyalive
    The left hand side Unity launch bar is color scrambled after reboot, or log on. When touching it with the mouse arrow, it comes back to normal. I installed gnome shell color before this started happening. I will uninstall gnome shell color & see if this problem goes away. Any one ever see this happen. I run a Nvidia 550ti ge-force graphic card. I have the latest 295.33 driver from Nvidia installed and it does show activated in my restricted driver window. Oh yeah, before you inform me, I can tell you that yes, I do see the instructions to report bugs to the correct source. But I really don't know if this is a bug or not. Could be something else.

  • Mouse pointer position to screen space

    - by Ylisar
    If I have a mouse pointer position in pixels of canvas, I can easily convert it to the -1..1 range for both X & Y by lerping by dividing with canvas dimensions. However, the problem is what I should put in Z & W if I want my screen space position to be on the near plane? The step afterwards would be for me to multiply by the inverse of view-projection to take me to world space, where I easily can construct a ray from the cameras world space position.
