This is bizarre. Three weeks ago I ordered some very expensive lockout tags ($16 each) for our linemen to attach to switches while they're working on a line. These are important safety devices, in that they inform anyone near the switch that there is work going on, and if the switch is changed, someone might die. I don't have a problem with the cost.
The problem is that the printer can't figure out how to print the company logo on the tags! They keep saying that they can't separate the colors properly, and need the original file. The original file is a .bmp, lovingly hand crafted in Paint years ago - that won't do. I've had printing done from our logo files for years, on everything from tee shirts to hats to magnetic signs. No one else has ever had such a problem.
I've sent the company our logo in multiple formats - .jpg, .pdf, .bmp, .ai, .gif - and I'm out of ideas. Is there some format that is used by the printing industry that is amenable to making color separations? Preferably one I can 'save as...' from Jasc Paint Shop Pro? We don't have Photoshop or Illustrator available, so that's not an option.
Is there a simple transformation I can use to process an existing file to create a source they can use? I know very little about the printing or graphics industries, so pardon my ignorance. This is getting ridiculous! Any suggestions would be most appreciated...

That is ridiculous. If you created the .bmp file, then that is what they should want. If they can't handle it, they should provide you a list of things they can, so you can convert it.
And, if all else fails, you could print it on paper and have them scan and print it where you want it.

I agree.
I did get some clarification, though. I just got off the phone with the people doing the printing, and what they need is a vector format such as can be created using Adobe products. Apparently, when I used CutePDF to convert the bmp file, it just embedded the raster graphic in a .pdf document. I can understand their problem with that, which the sales rep was unable to explain sensibly.
Now I need a raster to vector conversion tool, if such a thing is possible. A' Googling I will go... 
This has "long day" written all over it.

So they can't print a picture? I would spend 10 minutes finding another printer then.

Actually there are only a couple of vendors for this sort of product. Luckily I found a slick website - RO IT Systems[^] that hosts an online raster-to-vector graphics converter. It's an online implementation of the old sourceforge project, AutoTrace, that offers free conversions. I selected a EPS and a SVG output, and sent both. I'm waiting to hear from the vendor.

Something else you may care to glance at is Inkscape - this is a vector program that can output vector or bitmap formats, as well as having a function to create a vector representation of an imported bitmap.
The program is great for creating the multiple resolutions of an app's icon from a single image - like any vector app is.
Well, well, well worth the $0 rrp it has too. - Inkscape[^]

Hi
I m using Directx.Capture library in C#. In capture.cs one function named as GrapImg() which is used to capture image from video. When I call the method GrapImg() from button click event it works fine. Now I need to call it within thread from the main form. But it gives an error
Unable to cast COM object of type 'System.__ComObject' to interface
type 'DShowNET.ISampleGrabber'
public void GrapImg()
{
Trace.Write("IMG");
if (savedArray == null)
{
int size = videoInfoHeader.BmiHeader.ImageSize;
if ((size < 1000) || (size > 16000000))
return;
savedArray = new byte[size + 64000];
}
sampGrabber.SetCallback(this, 1);
}
Error comes from the line
sampGrabber.SetCallback(this, 1);
Plz help me to solve this problem.
Thanks in Advance

I just had the same issue. You have to call capture.GrapImg() in the same thread where the DirectX.Capture object was created. If you created it within the main form thread try using this.Invoke, that fixed it for me.
Best,

Hiii...
I wanna create a Gui like windows operating system for Linux. The latest Linux versions are user friendly .But I want to do this as a mini project just for practice. So my aim is a simple gui for Linux.
And there are so many gui development tools like gtk, Kdevelopr, Qt/...etc.
Which one I've to select , which one is better for my need. Presently I use Fedora 11.
Wait for a reply...
thanking you

Writing Window Manager for Linux is a very big project. It is not going to be a mini project, it is a life time project.
To write a Window Manager you will need to understand Linux at the lower level, you will need to read about Linux kernel, system calls, X-server and many other things. You cannot use Qt, KDevelop, GTK or any other library because they assume that a Window Manager is already running.
If this is only for learning then I will suggest that you write a program in top of an existing Window Manager and you can use Qt for that purpose. This means that your GUI manager will be an application in an existing window manager.

Sorry if repost.
What is the performance like of Managed DirectX vs Unmanaged DirectX, similarly how is the performance of the XNA framework vs home brewing everything? Is it worth investing anytime in learning something like XNA?

It all depends on what you are attempting to do, and what you already know how to do:
Reasons to Use XNA:
Don't know DirectX, or are not a control freek(XNA is just shorthand Managed DirectX..Basically). -Caviat You won't be able to modify meshes and models easily(at least as easily as if everything is done in DirectX.
Reasons to used Managed DirectX:
You want to be able to do things on the fly with your graphics, in managed code;
Reasons to Use DirectX:
You are my Idol.
If your going to be using c++ I would recoment Managed DirectX, you will be able to find a lot of resources.
If C# Use XNA Lots of resources and samples..
---Don't use XNA if you want to "Make" models... even Microsoft doesn't attempt to do this.
If you only want to display models..(move em arround etc...) use XNA.
If you wnat to blend between poses.. Use managed/unmanaged DirectX;I'd blame it on the Brain farts.. But lets be honest, it really is more like a Methane factory between my ears some days then it is anything else...

Hey there
I've got a strange problem... basicly I am writing an .NET (C#) application to render some stuff. By default the rendering works in an panel (Means the device uses the handle of the panel to render stuff there). So now I want to switch to fullscreen mode. Therefor I am creating a window with the size of my test resolution (800x600), release the pointers to the DirectX ressources and reinitialize the device with the window's handle and the fitting presentation parameters (.Windowed = FALSE, .BackBufferWidth/Height = ...). So far so good. It works fine!
Now I want to leave fullscreen mode after the user presses the escape key. I am catching the user input and close the window. The OnFormClosing-Event is connected to an method which does the same procedure descriped above in the other direction. It releases the device ressources and the device, reinitializes it with the panel handle and the presentation parameters (.Windowed = TRUE, BackBufferWidth/Height = 0). And this is the problem! I can see the cursor and how it changes if I am moving it around (and about window borders) but the display stays cleared and the resolution does not change. I don't know whats going wrong there, because if I am using Alt+Tab to select my window containing the panel used for rendering and closing the fullscreen window then everything works fine! (And no the problem also isn't the escape-key or the way it gets checked... this part is working, because the FormClosing-event gets fired.)
Any ideas what could go wrong?
Thanks in advance! http://www.aschratt.com

No. It sounds too complex for me, why don't you use a Panel in full size too? Just make your window full size, and fill it with the Panel, possibly by setting panel.Dock=DockStyle.Fill?

Allright... problem solved. I simply forgot to release all references to the device

I found a book on Geometric Algebra and from the introduction it seems interesting and promising. Supposedly, it extends linear algebra and then simplifies and makes intuitive all sorts of transformations commonly found in graphics, robotics, vision, etc. However, before I spend a lot of time plowing through another 600 pages of math, I thought I'd see if anyone is using it to benefit or has any opinion on it. I've been promised simple and intuitive by mathematicians before. 
For the uninitiated, the premise seems to be that you can produce a 5D space and use that to work with your 3D transformations somewhat analogously to the 4D homogeneous coordinates commonly found in projective transformations and everything is lovely.You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

Hi Guys,
I am not a web/graphic designer, but I would like to know if it is true that the web/graphic designs will affect the seo? Let's say for example if I have a lot of graphics, images in my website, does it affects the seo negatively?
Looking for the best answers from you Guys.
Thanks,

Yes in so far as the search engines look at things like file size, page load times, etc... But a large amount of images also give you several SEO advantages like img file names, alt tags, etc... The biggest thing you need to pay attention to though is that you don't use your keywords in your images, always make them text or your wasting your time, always optimize your images for the web, and pay attention to layout so your page is laid out in the following order usability/SEO layout/artistic design (which is different than good graphic design)
SEO layout is basically the SE only read the first 350-550 words on a page, so don't create a layout where a bunch of junk comes before your real content.
Hope these basics help

Hello,
I need to render the mesh.It is given by set of its surfaces
each surface is presented by its vertexes(x,y,z)
The camera and light source has to be placed at the same place.
I use this code:
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
GLdouble diam = m_allModels.getDiam();
GLdouble left = m_allModels.getCenter()[0] - diam;
GLdouble right = m_allModels.getCenter()[0] + diam;
GLdouble bottom = m_allModels.getCenter()[1] - diam;
GLdouble top = m_allModels.getCenter()[1] + diam;
glFrustum(left,right,bottom,top,diam,diam*3.5);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt (0.0, 0.0,2*m_allModels.getDiam(),
m_allModels.getCenter()[0],m_allModels.getCenter()[1],m_allModels.getCenter()[2],
0.0, 1.0, 0.0);
GLfloat light_position[] = {0.0, 0.0,0.0, 1.0 };
GLfloat white_light[] = { 0.7, 0.3, 0.2, 1.0 };
glEnable(GL_DEPTH_TEST);
glEnable(GL_LIGHTING);
glLightfv(GL_LIGHT1, GL_POSITION, light_position);
glLightfv(GL_LIGHT1, GL_DIFFUSE, white_light);
glEnable(GL_LIGHT1);
glShadeModel(GL_FLAT);
glEnable(GL_NORMALIZE);
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
for(unsigned int modelIdx = 0;modelIdx < m_allModels.zise();++modelIdx)
{
model curModel = m_allModels.getModel(modelIdx);
for(unsigned int modelSurfIdx = 0;modelSurfIdx <curModel.surfNum();
++modelSurfIdx)
{
surface curSurf = curModel.getSurface(modelSurfIdx);
glLineWidth(2);
glBegin( GL_POLYGON );
glNormal3f(curSurf.getN_x(),curSurf.getN_y(),curSurf.getN_z());
for(unsigned int vertIdx = 0;vertIdx< curSurf.size();++vertIdx)
{
unsigned int curVertIdx = curSurf.getSurfVertices()[vertIdx];
vertex curVert = curModel.getVertex(curVertIdx);
glVertex3f((GLfloat)curVert.getX(),(GLfloat)curVert.getY(),(GLfloat)curVert.getZ());
}
glEnd();
}
}
And I get this

So what is it supposed to look like? Can't read minds, you know...
I'll take a wild guess and say that, as is often the case with 3rd party models, the winding direction of the polygons is probably inconsistent. If you want to see the entire model, either enable double-sided rendering, or run the model through PoseRay (or some other model cleaner) and fix the polygon winding.L u n a t i c F r i n g e

If i have multiple child windows, each with it's own gl context, and I load up a texture with glGenTextures(), what's the correct way to go about being able to share the same texture with multiple contexts? Do I need to manually load in the image/texture for each context?

The fullscreen mode should be simply used for "viewing" (and only for viewing). The windowed mode should be some kind of editor. Anyway I do have to reinitialize the device after switching back from fullscreen mode (since this is set using the presentation parameters). And so this should not solve my problem, I guess...
