Vector Processing Tool

Hey guys im looking develop a program that will take a Vector image file, eg .SVG
And will rasterise this image (to bitmap) into an svg intelligently, ie at the minute im trying to use adobe illustrator to do this but it does it terribly. ie when i overlay a pixel by pixel grid onto the image a pixel that is say 1% black 99% white, is made black by illustrator.
so i will probably want to develop my own algotihm. Cant find anything else out there if anyone knows of anything let me know. Is there anything out there that would let me load an SVG and ovlay a grid and interogate the image pixel by pixel.
Even a starting point would be useful
cheers

we are looking to develop a program that will improve the way vector images are rasterised. At present if you try to rasterise an image with anti-aliasing turned off, it does it very poorly and the images will become highly distorted. Ie. if we vectorise an image and overlay a pixel grid and take a pixel that is 20%black and 80% white if we vectorise the image and go to this location, we will find that the pixel has been turned black.
So it has clearly took no notice of the white, now whats im saying if we done this better and analysed every pixel and determined the most common color, in this case white, and made the pixel this color then the rasterising would be much more effective than it currently is.
Currently im using adobe illustrator.

Slow, Blinking, Sluggish, Vector Path Tool

I am having problems with very sluggish tool performance in
both Fireworks and Flash drawing tools. I shyed away from
Macromedia applications in the past due to their sluggish, awkward
interface. I don't think any of that has improved.
So someone give me a clue as to sluggish tool peformance. For
instance, when using the Vector Path tool, it feels heavy and
sluggish and very innacurate and takes forever to update a stroke
let alone it blinks on and off as soon as I select the tool.

Annotation process tools build performance issue

Annotation process tools is taking 85 minutes to compile page flow files. Is there any suggestion to improve performance.

As you probably already have gathered, you have different execution plans in the two environments. There could be different reason why this happens, for instance different profiles of the data. But more likely it is due to that in the slow environment, the
plan was built from some atypical set of input parameters, which causes a performance issue when the procedure is run in a normal fashion.
When you say that the query has a lot of isnull and convert functions I get a little worried. If it is only in the SELECT list, it's not evil, but if functions are used in the WHERE or ON clauses, the query might benefit from a review, and possibly also
the data model. But this is pure speculation at this point.
I would suggest more than one course of action. As a short-term solution, you run UPDATE STATISTICS WITH FULLSCAN on all tables involved, as out-dated statistics can also be explanation for why you got a bad plan. New statistics should trigger a recompilation.
But even if this resolves the issue, it may not be feasible in the long run, because the events indicate that the query is sensitive to something and the bad plan could come back any day. For this reason, it might be a good idea to make sure that the query
does include inappropriate constructs, and you also need to review that there are good indexes in place.

Simple word processing tools

Would someone please tell me how to highlight a selected word with a desired color? I have not been able to find a button and I'm sure it must be there.
Also, is there a way to get Appleworks word processing to underline misspelled words as you go along as is done in Microsoft Word? I can't find that option.
Thanks
Seebie Zoo

I assume by 'highlight a word' you mean enclose it in a coloured box? To do this:
1. Click on the rectangle tool in the toolbar.
2. Click on the 'line weight palette button' (second from the bottom, to the right of the 'T') and select 'none'.
3. Click on the fill button (second above the 'T').
4. In the colour palette (fifth up from the bottom) select a suitable colour.
5. Dragging with the mouse, draw a rectangle over the word concerned.
6. From the 'Arrange' menu select 'move to back'.
Note that if you amend the text prior to this word you will have to move the rectangle to match.

Why does the vector selection tool (white arrow) change layer selection to another vector mask?

I have been continually annoyed, when creating a vector mask-heavy document, with trying to select vector mask points by dragging a rectangle only to find that it instead selects a layer higher up which has a larger vector mask.
The only workaround is to manually select the points of my mask or to drag a rectangle from outside the canvas, meaning I have to zoom out or scroll to the edge - sometimes annoying if I am zoomed in quite far.
Does anyone know any resolution for this?
I know that the move tool can be set to automatically select a layer, depending on what part of the image is clicked, but why is there not an option to turn this off for vector editing?

What version of Photoshop are you using????
The White Arrow tool is the direct selection tool and it work best way you point it at a path segment line and click once. When you do all the control points in a close path segment will be marked with little squares and the two control point adjacent to where you clicked will have handles you can adjust.
You can also drag out a rectangle with the direct selection tool. When you do you may select many closed paths in a path a path may have many sub paths and each has a mode like add, subtract, intersect etc, and each has a stacking order like in a layer stack. So if you drag out a rectangle many paths control points will be marked and control point adjacent to crossing rectangle will have handles. Can be very confusing.
Here are two screen capture the first on shows the layer palette and path palette. You can see many shapes and path with sub paths and modes. I also targeted layer a vector mask. The selected the direct selection tool and in the image window I pointed at the 45 degree oval path near the top right. You cab see the four control points and two with handles. The second screen capture I only captured the image window. I used the direct selection tool and draged out a rectangle and you cab see many segments control points and many have handles. I have no problem selecting what I want to select

Vector path tool question

Is there a way to make an irregular shape with multiple
vector path lines and then fill this shape with color? I tried this
with a shape like a box but with curves and straight lines but it
won't fill correctly. I did join the multiple lines together but
the curved lines fill independently. I know there has got to be a
way to do this, but can't figure it out. I did try different things
with combining/altering the path but was unsuccessful. If there is
a way to fill this shape with color as a single object, can effects
be used such as bevel/emboss on this shape? Any help would be
greatly appreciated.

I suggest you view this tutorial. It will show you the basics
of the Pen
Tool.
http://www.communitymx.com/abstract.cfm?cid=D01EF
In order to join to paths you have to use the Subselect Tool,
select two
points you want to join then go to Modify > Combine >
Join.
You can also use the Subselect Tool to drag an end point
close to the
other end point. As you get close it will snap into place.
The Subselect Tool is the white looking arrow to the right of
the black
one at the top of the Tools Panel.

Vector processing?

I notice the chips in the new Mac Pros include a vector processor (maybe eight of 'em even?)
Just wondering, can this be expected to enhance real-time processing in LP8, or is it just a video thing?

How to count number of vehicles using image processing tools in LabVIEW

anyone can give me idea that how to do counting of vehicles using image processing tools

Hello,
if camera is stationary, first take an image of the background. Then subtract each acquired image from the reference image. Limit the region of interest - build a mask of the area, where you want to detect vehicles. Use only the pixels that are under the mask for further processing. You probably would need to do some morphological operations (for example dilate) to make the detection more noise-free...
Maybe you could get more reference images (different time of day) and compare the average intensities of the acquired and the reference image to select the best image for subtraction.
You could then probably just count the numer of objects to get the number of vehicles.
You can perhaps also use optical flow to track the vehicles, but you would need to compute some features for example strong corners for each vehicle (check good features to track, http://docs.opencv.org/modules/imgproc/doc/feature_detection.html). Or you can use the new mean-shift tracking library (Labview 2013).
Hope this helps a bit.
Best regards,
K

Signal processing tools: spectrum analyzer, equalizer available?

Are there any plug-ins or scripts to perform spectrum analyzing (shows the distribution of frequencies), and an equalizer (multiple band pass filter)?
Why is there a high-pass filter, but no low pass filter?
(using cs4)

Math abstraction notwithstanding, the results are not the same. For one thing I get problems with using blur around the edges of an image.
But even beyond the edge issues...
In the case of my example - preparing for a luminance flattening operation - the blur combines the data from all the background sky glow with that from the stars, and so the result contains pixel values derived from both. A high pass operation then subtraction leaves me with the background sky glow alone and only eliminates the stars (light spots) and dead pixels (dark spots). If I choose to combine so as to allow only darkening then I keep the dark spots and eliminate only the stars.
Am I missing something here? Are you saying the sky glow somehow influences the result from the high pass filter operation as well, so that the resultant sky glow after subtraction is affected?
I guess what you're saying is that High Pass is based on blur under the covers then?

How do I 1)use airbrush type tool in illustrator CS4 or 2) use PS4 airbrush tool on vector line art?

That's basically my question in a nutty nut. I am drawing illustrations in Illustrator,
can't find an airbrush tool there, so I export to Photoshop to use that airbrush and the
lines pixelate. I want the clean, vector lines of Illustrator with the yummy fuzzy airbrush tool. In short, can I go back and forth from Illustrator to Photoshop without the line art ping ponging between pixel and vector?

See this PDF for one approach. The subject was really more about exploring ways to exploit Isolation Mode, but it does so in the context of a poor-man's "airbrush" effect.
I want the clean, vector lines of Illustrator with the yummy fuzzy airbrush tool.
In reality, then, you're not wanting vector artwork to look like vector artwork. Here's the thing:
Vector artwork, is by its fundamental nature "hard edged." That's one of its advantages and one of its disadvantages. Soft-edged fuzzy effect (and its sister, texture) is one of the mainstays of raster imaging. It's one of the main reasons why there are two primary kinds of computer graphics.
Historically, soft edges and graduations are primarily done with Blends and Graduated Fills. A Blend is really just a semi-automated stack of multiple paths with incrementally changing color. Grad fills are mathematically-defined variations of a path's fill color across the path. Generally speaking, grad fills are limited to a small set of geometric shapes. For most of Illustrator's history that was a very limited set: linear or radial. So when you needed to render tonal graduations in more elaborate shapes, you employed Blends.
More recently, programs have acquired a newer construct, which is an elaboration of grad fills: Mesh Grads. Mesh Grads are also mathematically-derived and remain as such up to print time--that is, they are vector. They offer more control over the shape of the color transitions. But that control is quite tedious, and is not at all like painting with an airbrush.
That's about the extent of it when it comes to maintaining "clean, vector edges". With skill and discernment, the results can look just as realistic as airbrush work, and it can be entirely vector. But the interface for doing it is not an emulation of painitng with an airbrush.
Far more common than a purely vector tool in a vector drawing program that tries to act like an airbrush is the workaround of applying filters or effects to vector paths. Doing that is not purely vector: It's actually rasterization that is re-applied whenever you edit the paths. If you set such an effect as the current default, then you can draw paths with the Brush tool, the Pencil Tool, or really, any of the vector path tools, and that's about as close to emulating an airbrush in a vector program as you'll get. The PDF mentioned above employs that kind of approach. But you should understand, you're really creating raster images when you do that. It's just that, rather than the raster images being "nailed down", they are effectively deleted and re-created on-the-fly if you edit the paths to which the effect is applied.
Illustrator isn't great at this. Other programs--Xara Xtreme in particular--do it much faster and responsively. But again, even though it retains the lossless editability advantage of vector art, the soft-edged effects are not really vector art. The are on-the-fly rasterizations of vector art.
Look up Blends, Grads, and Mesh Grad in Illustrator's Help files.

Need to convert to vector format.

I have a document with pictures. I need to convert it to vector format before sending to printer. Not sure how to do it. Using CS5. Is converting to outlines the same?

It must be difficult to convert from illustrator into a vector format since no one has a specific answer.
Soshagayle7,
There is no automagic "conversion" from a raster image to a vector graphic. The artwork represented by a raster image can be redrawn as vector artwork.
You can re-draw the artwork using the vector drawing tools in Illustrator or any similar program. You can even import the raster image and use it as a guide while "tracing" it with vector paths.
Or (and this is where the all-too-common misconception about "conversion" comes in)...
You can use the autotrace feature which exists in Illustrator or any similar program to try to automate the process of "tracing" the raster image with vector paths.
Either way, you end up with what would more accurately be called a "reinterpretation" of the subject, not a "conversion" of the raster image in the sense of "converting" one file format to another.
And that's the key. All that most current autotrace features (including the one in Illustrator) do is detect color differences between pixels of a raster image based upon a user-specified sensitivity setting, and then try to draw vector paths which follow along those detected differences. It's very much a garbage-in-garbage-out process.
And even when the "in" is not garbage, there is no real intelligence involved. The kind of autotrace algorithms in Illustrator and programs like it have no shape-recognition intelligence. For example, in the case of a human face, the autotrace feature doesn't know that the eyes' pupils are round; it just detects a region of similarly-colored pixels and tries to draw a path around them. Similarly, in the case of a geometric logo that obvously (to a human) is supposed to contain a perfect circle, the autotrace feature doesn't "see a circle"; it doesn't go and get the Ellipse tool and draw a circle that fits, as any human would do. Again, it just tries to follow around the regions of similarly-colored pixels.
But that sounds okay, right? Well think about it. Imagine turning the sensitivity of such an algorithm way up to the max. What's going to be the most accurate autotracing of a raster image? The mathematically "most accurate" result would be a perfect vector square for each and every pixel in the image. And the "vector advantage" of that would be absolutely nill. The resolution-independence reason for preferring vector paths would be rendered moot. Such a graphic would be entirely vector, but to absolutely no advantage regarding scaleability. (Thus my comment about the line drawn with a 1-pixel raster image.)
So the reason you haven't received an answer to the "how do I convert" question is because the same thing has been explained in this forum countless times, and to answer it correctly really requires a lengthy explanation (like this one) that tries to clear up the too-common misconception that autotracing is some kind of magic bullet for "converting" a raster image into a vector graphic in some kind of mathematically accurate way that then yields all the advantages of properly drawn vector graphics.
Autotracing is useful to those who understand when it's appropriate and why. But without seeing or at least knowing more about the actual raster image you are dealing with, advising whether it's appropriate in your case is nothing but a guess. Generally speaking, if the image in question is not already of high enough resolution at the size at which it will be printed, then it's probably also not of high enough resolution for good auto-tracing results. And if it is of sufficient resolution for the size at which it will be printed, then there's probably no reason it needs to be vector.
Bottom line: There's a good reason why vector graphics are preferred. But that means properly-drawn vector graphics. The best way to "convert" your raster image to a vector graphic is to re-draw it using the vector tools. The sometimes-acceptable but often sub-standard "cheat" for doing it is to import the graphic and apply the autotrace feature (called LiveTrace in Illustrator). It's use is explained in the online help.
Autotracing--the "conversoin" that such questions are almost always talking about--is not a lossless translation, like converting quarts to gallons or binary to hexidecimal. Entropy always rules. Anytime something is automatically "reprocessed" something is lost, not gained. You see that in everything from repainting a room over and over without removing the old paint, to taking photographs of photographs of photographs. Degradation occurs. You swap one kind of ugliness for another. That's autotracing when used inappropriately.
The drawing tools exist for a reason. If you really need vector paths, you should probably draw them.

What tools would you use to make these kinda pictures/symbols?

Would love to know the simplest way you people can do, step by step illustrations would do more
thanks
markus

Vector-based paths 100% all the way. Raster-based art often stinks for things like logos and symbols.
Photoshop is very good in some respects at creating vector art. I really LOVE the keyboard shortcuts in Photoshop for the vector-based Pen tool. Using Shift, Ctrl, Alt and Spacebar on Windows or Command, Option, Shift and Spacebar on Mac you can manually digitize vector paths over scanned art, make adjustments to those paths and zoom in/out and hand pan the view. I really wish Illustrator (and CorelDRAW) used the same keyboard short cuts. They really speed up the process of manually drawing clean paths over hand-drawn or scanned artwork.
Illustrator is a great tool for this purpose for all the extra vector-based tools it has that Photoshop does not. CorelDRAW is also very good. However, they're best at techie looking things while Photoshop's pen tool strenghs lend themselves to accurately digitzing more "organic" looking shapes.

Is there a way to edit vector data within a placed Ai file?

When I place aa Ai file in InDesign it its seems to be one group and I want to take advantage of the vector content within that group. Group and Ungroup are greyed out.
I'm using cs5.5.
I've only been using it for 2 days and am new to InDesign.
Any suggestions?
Thanks.

The way to edit an AI file is to right-click the image and select "Edit original"
If it's just some simple objects, I find Bob's suggestion of copying them into InDesign worth the effort. Then again, if you have to edit them at a regular base, InDesign's vector editing tools are slightly less advanced than Illustrator's (admittedly, by a narrow margin; but some things are just a bit easier to do in Illustrator).

Bridge CS5.1 Tools are missing and there are no startup scripts available.

Brand new MBP with Creative Suite CS5. Not sure what happened to the Bridge Image Processing Tools that where readily available in CS4. I looked for the Startup Scripts mentioned in other forum posts but this folder is empty: Library > Application Support > Adobe > Bridge CS5.1.
Why make us hunt for Startup Scripts?

I think you may be misunderstanding me.
With many advantages with using mail for this forum the disadvantage sometimes is you don't have oversight in the whole thread.
I was merely reacting on Curt with the CS5 and CS5.5 solution that solved some problems earlier this year but reading the thread again that seems not related to yours.
Shortly before Curt his post I read your post about renaming the default folder name (which to me sounds bad). Hence my reference to a solution of an older problem that was solved by creating a new folder with the 5.1 addition and copy the scripts in there
However I still don't understand why you are not able to have a normal setup after clean install.
Without having experience with Lion I really would try the Recovery Disk for resetting your user account. With Pre Lion you could do an Archive and Install and it seems Lion also has such an option.
