Studiohack has the "thorough" approach but heres a short hack: Enter the domain name like http://superuser.com/ Add favicon.ico to the end Press enter (this should be in url: http://superuser.com/favicon.ico Right click on image and save as
I decided to write a bit about the programming aspect and how components talk to each other. Maybe it'll shed some light on certain areas. The Presentation What does it take to even have that single image, that you posted in your question, drawn on the screen? There are many ways to draw a triangle on the screen. For simplicity, let's assume no vertex ...
It's hard to understand exactly what it is you don't understand. The GPU has a series of registers that the BIOS maps. These permit the CPU to access the GPU's memory and instruct the GPU to perform operations. The CPU plugs values into those registers to map some of the GPU's memory so that the CPU can access it. Then it loads instructions into that ...
First I must apologise as in my haste to find out just what your card was, I missed the nuance in your question that stated (quite clearly, now I look at it again): I am trying to use the card for certain games, and although the graphics seem fine, cinematics within the game stutter badly. It would appear that it is not the actual horsepower of the ...
I always say Raster records the pixels in the picture. Vector records the steps it took to draw the picture. So if you enlarge Raster you get a big picture with big pixels. If you enlarge Vector the computer follows the steps to redraw at higher resolution. If you have a chance to demo it for them, load up Word and put in 1 small (raster) ...
That's (partly) the role of the BIOS. The Basic Input Output System of the computer is responsible for providing a common interface to operating systems, despite such differences between actual computers. That said, for graphics specifically, there are different ways of drawing to the screen. There are TTY commands that you can send to the BIOS, but that's ...
From the early days of the IBM PC and its clones, the display adapter hardware was very simple: a small block of memory was dedicated to a grid of character cells (80x25 characters in the standard mode), with two bytes of memory for each cell. One byte selected the character, and the other selected its "attributes" - foreground and background colors plus ...
by reading http://en.wikipedia.org/wiki/Favicon you can also find that: The following format is cross-browser compatible and is supported by Internet Explorer, Firefox, Chrome, and Opera. <link rel="shortcut icon" href="http://www.example.com/myicon.ico" /> Additionally the following is also acceptable: <link rel="shortcut icon" ...
PngOptimizer 165KB in about 2 seconds. Image quality is untouched.
The ffmpeg command line tool does this: ffmpeg -y -i "image_%03d.jpg" output.m4v ffmpeg will, in this example, look for files matching the pattern image_xxx.jpg in the current directory where the xxx part is a zero-padded decimal number, like 003. ffmpeg automatically chooses the output format based on the suffix of the output file, e.g., m4v. I suggest ...
Here is an annotated list of alternatives to MS Visio. SmartDraw is considered a close match to Visio. Otherwise it includes: Inspiration TeamFlow iGrafx FlowCharter Kivio Edge Designer FlowBiz PathMaker RFFlow Patton & Patton Flow Charting Graham Process Charting Software allCLEAR OmniGraffle
At least for documents created directly in Inkscape, File > Export Bitmap... works as expected. If the document has transparent background, the exported PNG becomes transparent. If it was white, then PNG becomes white. Please check File > Document Properties > Page > Background and check the aplpha channel (A). On RGB tab set all values to 255, including ...
Inkscape can export SVG to bitmap formats.
I'm the guy behind Glyphish. There's a few ways to change the color. Easiest is go to Edit > Fill, then choose Color from the first dropdown, ensure Preserve Transparency is checked, and hit OK. Happy to explain in more detail; let me know if you get that to work.
I've only ever used pngcrush but it works well and has plenty of options.
Yes, the PAL standard does have a vertical resolution and we can estimate the horizontal one. PAL is analogue but in most cases we can safely use the standard digital resolution 704×576 to represent a PAL picture. The details are below. The vertical resolution is truly discrete PAL is an analogue signal however it is defined to have 625 discrete lines in a ...

I had the same issue. To edit the background: Click on View -> Slide Master Click on View -> Slide Master again. All the background images will become editable and copy-pasteable. Definitely not intuitive.
If you are on the command, line I recommend that you use "convert", a command from the ImageMagick Package. try: $ convert -enhance -equalize -contrast image.jpg image_enhanced.jpg
The problem is unfortunately an old bug with ATI cards under some multi-monitor setups that is being reported since at least 2009. I experienced it with an HD 4770. It was particularly recurring when I would host a virtual machine in fullscreen mode on my secondary monitor. But would also happen without it when I moved between screens. Just not so often. ...
It looks like the problem is that Photoshop doesn't support part of the PNG-8 standard. PNG-8 like GIF uses a 256 color pallet. Both formats support using one of those 256 indexed colors to represent transparency, PNG-8 also supports setting an alpha-value for each of those 256 colors on the pallete. Photoshop (apparently CS3 and CS4) doesn't support this ...
It is a somewhat old question but I have just found it and I think it needs some clarification. (Update: Now it is a somewhat old answer - please note that it is specifically about HDTV and signals and resolutions that can be transferred with a standard HDMI cable. When I say "there is no 720i" I don't mean that it's impossible but that standard HD TV sets ...
Just for a quick benchmark, I downloaded 170 random PNGs from different websites on the internet, totaling about 8MB. Here are the results: Original: 8,403,619 bytes total PNGCrush: 7,398,194 bytes total Optipng: 7,340,167 bytes total PNGOUT: 6,938,205 bytes total So it seems PNGOUT (or any GUI based on it) is the best choice if size is your primary ...
There is a freeware AppleScript-based application by the name of Sequimago which should fulfill your requirements admirably. It is available from this page at MacScripter, a forum site where Martin Michel, Sequimago's author, is an administrator. This is his description of the program: Requirements Mac OS X 10.5 Leopard • QuickTime 7.2.1 ...
Also check out Inkscape. It's a free vector/image program, good for logo work and design.
I am not sure at what level of curiosity you are asking this question, But, in general I'd refer you to the Wikipedia Computer Graphics page. There is also A Critical History of Computer Graphics and Animation link there. You could jump to the section of interest from their contents page. Update: I wonder if your question is based on concepts related ...
Screen size has nothing to do with video performance. Resolution does: the higher resolution, the slower (which is logical since you have to calculate/draw more pixels). Of course, bigger screens usually allow higher resolutions.
During boot the system BIOS looks for the video adapter. In particular, it looks for the video adapter's built in BIOS program and runs it. This BIOS is normally found at location C000h in memory. The system BIOS executes the video BIOS, which initializes the video adapter. Which levels or modes of video/graphics the BIOS can display natively, without an OS ...
