Vector vs. raster

Hi, Experts
Why does this happen?
I used MapViewer to define basemaps: two base map: one is Vector, the other is Raster; both base map use same parameter, however, the tile width/height are different?
Any idea?
Why can not add Raster theme on top Vector theme if I use MapViewer - AJAX ?
No error shows up, and also no raster map shows up.
Thanks. If anyone could give a hand.

When you put the images in a vector slideshow overlay you change the display experience. You'll see a low-res version of each image show up first, then the high-res version snap in. Many publishers don't like that experience. You make the overal folio side larger too, as we have to embed both the full-size image and the lower-quality thumbnail images.
Unless you are creating a single edition application you should publish two renditions, one SD and one HD. Create your designs as 1024x768 InDesign documents and place images in your slideshows that are large enough to be nice on a retina ipad. Use a raster slideshow.
Then use that source InDesign document to create articles in two folios: one at 1024x768 and one at 2048x1536. We'll be smart and scale the images in the slideshow based on the size of the folio. If you have a sidecar.xml file the work to create the second rendition in Folio Builder Panel is very fast. You can create an empty 2048x1536 PDF folio and import all the finished InDesign articles at once.
Publish both folios and you're done. Beautiful content on SD, beautiful content on HD.

Vector and raster within one unflattened PS file?

Is there a way to save and submit a Photoshop file containing both vestor and raster art-unflattened-so that it stays vector and raster when the client opens it? The issue is: client wants to be able to zoom in on the whole file and not lose sharpness of the type. Seems like a reasonable request. So the finished, unflattened file needs to include both types of layers. Someone suggested using Indesign. Could that work? Didn't Deneba Canvas used to work that way? Can someone point me to a Knowledgebase article that covers it? I posed this question in the Illustrator Forum as well.

Thanks, Semaphoric. I lost track of saving as a .PSD file.I usually save as TIFF. That should work.

Vector with raster edges in Fireworks.. Why?

I am new to Fireworks so I have one newbie question :)
If Fireworks is vector / raster program, why when I draw
something that is complete vector in it with a pen tool I get
pixelazation ?

I'm betting your screen displays things in pixels just like
mine does.
Fireworks is designed to display things as you will see them
on the
screen when they are exported. Aside from that, do you have
anti-aliasing turned on?

Vector to Raster?

This may sound odd, but i was wondering if it's possible to export my .ind as a pdf and have the text rasterized rather than vector.
This is because the mag in question is more or less online distrib only, and is largely read on Issuu, which doesn't render vector text with anti-aliasing. Thus the text becomes quite dificult to read
I have not found any setting or answers in the FAQ of Issuu. Peaking at other magazines, the majority had their text rasterized and it was much easier to read.
Any tips?
Thanks either way!

If you export to jpg, with compression set to a minimal setting, you would get a fully rasterized page and the text could still be quite readable. You can choose the ppi of the raster, too, in that dialog box. As a second step, those jpgs could be saved as PDF, if need be.
But, no, Smallest File Size won't tend to rasterize text.

Vector to Raster Conversion

I am looking for a solution to batch rasterize vector images inside of a large library of multi-page pdf documents while leaving text and links untouched.
Also,
I produce technical manuals using FrameMaker 7.2. The vector images are primarily created with Illustrator CS2. I would like to be able to leave my native files in tact and rasterize the vector images when I distill the FrameMaker documents.
Can anyone suggest solutions for these two situations please?
Thanks,
Mark

Mark,
Importing the Illustrator .ai files into FM is really a no-no since FM
doesn't actually support the .ai format. This is an accidental
conversion in that the .ai format is a pseudo-pdf. FM's internal PDF
filter is recognizing that component and rendering it. You may
actually be losing content without knowing it. If you are editing in
Illustrator, then you can save in image format, but this would require
re-importing into FM. You could automate this using FrameScript.
As far as changing things in existing PDFs, you may be better off
asking in the Acrobat Forums. However, I don't think this will be an
easy one, as a vector is a vector, and any line on a page (a footnote
separator, table rules, etc.) would be a candidate for a conversion.
You'll need an operator to mark the area of the drawing that needs to
be rasterized.
You may want to consider other security measures to lock down the PDF
to prevent copying the contents and/or build in a print function via
the scripting that forces the hardcopy to print as an image (see
Advanced functions in the Acrobat print dialogue). The benefit to this
would be that your users get to see the highest resolution possible
(the scalable vector drawing) and there is minimal impact on your
workflow.

Enlarging raster vs vector Objects

as i understand it vector objects should enlarge without losses, while
raster objects pixilate on enlargement.
In this image
http://img212.imageshack.us/img212/6178/triangleswithrastercz0.gif the
top triangle is raster. The bottom one is vector. Otherwise the two
are identical. I stretched both about 15 fold using transform. They
are identical. If you magnify them to 800 times actual size the
pixilation is the same. So, the raster image enlarged exactly the
same as the vector image??????

Somehow I'm not being clear. I understand the difference between
vector and raster objects/images. My point is, theoretically upsizing
a vector image should give a different (better/cleaner/smoother )
result than resizing a raster image. Yet, in my example upsampling
by a factor of 15 times showed no difference.

Photoshop CS6 Scaling issues: Vector/Raster smart objects

My team and I have noticed some strange issues when affecting the overall interpolation of a .psd via scaling, cropping, or canvas resize.
Test:
Original .psd is even x even overall pixel dimensions.
Original vector and raster smart object assets are all proportionally scaled with width x height percentages equal.
Preferences: "Snap vector tools and transforms to pixel grid" is turned off
Resize .psd via Image > Image Size palette.
Scale styles, constrain proportions selected.
Every interpolation style tested.
Resize the .psd to 50%
Result: All smart objects (both types) no longer are proportionately scaled. Usually off by a minor amount under 1/10th of a percent.
Some objects' center point shift a half pixel to the right or left.
This also occurs if we use the crop tool or resize the canvas.
Is this a known bug and if so, is there:
1) any setting to truly lock proportions?
2) any resolution being pursued currently?
Though the shift and the disproproptions seem minor, the overall quality of items such as icons, hairlines, and other things that should be more crisp become far more degraded in CS6 vs CS5.
We have over 100 users and need to evaluate if we should drop back down to CS5, where we weren't having any of these issues, as our work demands a lot of precision, so you can see why this is worrisome.
Thanks!

I'm not going to say anything about the abysmal rendering of Vector Smart Objects in CS6 because it'll be beating a dead horse but I can explain the issues you see with measurements after scaling.
The slightly disproportionate scaling and half-pixel shift of the centre is unavoidable when it happens because the resulting Smart Object/Vector Smart Object must measure an integer number of pixels in height and width and be perfectly aligned to the document pixel grid. That's true in CS5 and CS6.
Say a SO/VSO originally measures 102 x 103 pixels and you scale it by 50%. The Options bar may say the result is 51 x 51.5 px but the result will really be 51 x 52 px, and therefore the new height will really be 50.49% of the old height.
The original SO/VSO is an even number of pixels wide and an odd number of pixels high, therefore its centre will be halfway down a pixel. The 50%-scaled SO/VSO is an odd number of pixels wide and an even number of pixels high, therefore its centre will be halfway across a pixel.

Layered vector AI file with raster (Photoshop) layers included as vector layers?

I've been using Illustrator since the late 80's but this request just now came up for the first time, twice in one day: the clients each want me to send them layered files (OK-no problem) wherein all the layers, even the raster layers, register as vector layers. Or at least all the layers, regardless of file-type (vector or raster) are contained within an unflattened Illustrator file. One of the clients specifically asked that the Type layer (No problem-all the type is on one layer) be "vector mapped", whatever that means, while all the other layers can be Photoshop layers, if necessary. So how do I hand them an open, unflattened Illustrator file containing both vector art and raster art? Can someone point me to a Knowledgebase article or a previous post that addresses it? Can it be done in Acrobat, as a PDF? I'm working in AI and PS CS5, but I can and will upgrade if I have to.

I read your post in the PS forum as well.
Point is, just send them the unflattened AI or PS file with live type--type that one could double-click on the text layer in PS or use the type tool in AI to edit the text. That's the gist of it. Hopefully they have those fonts. If they do not have the fonts, you can outline the type in AI and it is still vector, just not editable as type.
And you likely have some client education needed. They need to understand the ramifications of using live type insofar as they need to own the exact same fonts you are using (you cannot legally just supply the fonts, they need to purchase the fonts) in order to prevent issues if they want to edit the type.
And yes, you can export as a PDF and keep the text live depending upon the effects used, else it could be rasterized. Something they evidently do not want.
Good luck. Mike

How do I move a pattern layer independent of its vector mask?

I've created a pattern fill layer and assigned a vector mask to it. How do I move the pattern around without affecting the mask? I realize if I want to rotate the pattern I'd need to convert it to a smart object, but if I only need to adjust the pattern location there must be some way to do that without moving the vector mask along with it. A traditional layer shows the vector and raster mask layer with a lock icon, but fill pattern layers are different for some reason. Can someone "fill" me in?

rcraighead wrote:
Yes, I understand that. I am working with pattern layers, not layers filled with a bitmap pattern.
That is not what your showing above in red above your showing a shape layer in CS6 a pattern fill layer with a vector mask is a cs6 shape layer. Even the icon on the layer's content in the layers palette shows its a shape layer. You can edit the vector mask you can not unlink it. For its a cs6 shape layer. As you noted you can first convert pattern fill layer into a smart object layer. It then acts like a normal pixel layer with an associated transform to the canvas size. Your no longer dealing with a pattern fill layer. When you rotate it you will have the same problem with the layers corners areas. CS6 changed shape layers design they have more options then prior versions of Photoshop and prior versions of Photoshop can not handle CS6 shape layers that used cs6 shape options like stroke, line type, and pattern fills.

How do I save a JPEG that includes text as a Vector image in photoshop?

I have a design that includes some text. I need it to be saved as a vector image , photoshop pdf to send off to print. They keep telling me there is an embedded jpeg in the file. how do I fix this?
note: Im using photoshop CC, I do not have access to illustrator, indesign etc...

A pdf can contain both vector and raster data. Any images in your design would be raster. The settings for the pdf determine how to handle the raster data. One way it can compress the images is to store the images as jpg.
If the service is expecting a vector file, then there can not be any raster data in that file.
The only true way to make sure the entire file is vector is to use illustrator.
Just an fyi, even if you import an illustrator file into Photoshop, that data will be raster, because Photoshop rasterizes the data when importing it.

Does illustrator cs4 draw in vector?

Hello I am looking to buy what adobe program I need, I was told adobe illustrator is a vector drawing program. Ok so my question is does that mean it is only capable of converting to vector or does that mean that if i start a new document (ANY TYPE OF DOCUMENT) and create a design will the design be in vector format?
Reason I am asking, I am currently the owner of a small sign, banner and decal business and I am running FlexiSign for my Cutting Machine. For My banners I subcontract the jobs to a bigger outfit who has proper machines to print. They need all designs to be in vector, .pdf format. So instead of having to convert everything all the time I want a program that can make the design and it is already in vector, than if i need to import a raster image I understand that I will than need to convert to vector and that is fine, but for the backround and font and whatever else I put in the design does illustrator draw in vector, like my flexi sign does, because if I create a job in flexi sign and send it to him it is already in vector, I would rather be using a adobe product...........PLEASE HELPPPPP

Matthew,
Illustrator is primarily a vector drawing program.
That does not mean that everything in a given Illustrator document is all vector artwork. An Illustrator document can contain vector paths, text objects, and raster images. It contains features that perform rasterization on-the-fly in order to apply effects to vector paths.
Nor does something being "vector" necessarily mean it is suitable for vinyl cutting. For example, you can apply gradients and blends to paths, and everything is "vector"; but you would not be able to render it on a vinyl cutter. For an even more basic example, you can apply strokes of any weight (thickness) to a vector path; but that by itself does not make it suitable for cutting--if you sent it to a cutter, you would just get a single cut along the center of the path.
So yes, you can use Illustrator to draw the kinds of paths that you need for your vinyl cutter. Many people do. (Corel Draw is more popuplar among sign shops.) But you need to know what you're doing; which features to use, which to avoid, and how to properly optimize the vector paths for cutting (removing overlaps, merging cross-cuts, outlining strokes, etc.)
You'll most likely need to back-save the properly-prepared artwork to an earlier version. Most vinyl cutting software can import .ai format, but not usually the current version.
Your designer is working against you by building artwork in Photoshop, if that artwork is intended for
cutting. For vinyl cutting, the artwork should be drawn as clean vector paths.
Except for certain "special cases", autotracing raster images should not be used for vinyl cutting. And in those cases, you need to fully understand what you are doing. Give up on the misconceived idea that you can just create any artwork you want, willy-nilly in Photoshop, and then use autotracing to magically "convert" it to vector artwork. That is a myth. Usually, you'll just be substituting one kind of jaggedness for another. (I've seen many sign shops do this, thinking the resulting roughness is "normal", and turn out garbage.)
You say you contract out your "banner" work to an outfit that has a large-format
printer. Yet you say that outfit insists on everything being vector. That is rather contradictory. You need all vector paths for
cutting. But any decent large format
printer can print artwork consisting of vector paths, raster images, or a combination of both.

Adobe CS5 - How can I place vector shapes behind a mask?

Hello,
I am creating a logo in Photoshop which will have rows of horizontal lines that form the shape of a hexagon.
This is what part of the logo will look like:
I used the Vector Shapes tool to create the lines, because I will need to re-size the logo without distorting it.
I want to use a mask shaped as a hexagon to cover the edges of the lines. Here is how I created the hexagon mask:
New layer
Polygon tool
Changed the setting to Paths
Created the hexagon
Went to Layer > Vector Mask > Current Path.
After I created the mask I tried to see if I could copy and paste the lines (still vector shapes) into the blank area of the mask, but when this happened the lines were converted from vector to raster form.
What is the best way to mask multiple vector shapes without changing them into rasterized images?
Here are the screenshots:

AFTER:

Did you try clipping the two layers? Place cursor between layers, hold down the alt/opt key and click.

Vector smart object? Big deal.

My primary use for Photoshop is for producing illustrations rather than manipulating photographs. With that in mind, I don't understand the revolutionary nature of "Vector" Smart Objects, since once they land in Photoshop they cease to have any "vector" qualities. They can be resized, distorted, and made more or less transparent, which is fine, but all those things can be done to any raster Photoshop layer. So my feature request is: since Photoshop's Path tool can deal in vector art within Photoshop, why can't that facility be extended to the Smart Objects? I realize that what I am asking amounts to asking for Illustrator to be installed inside Photoshop, but why not? I think there was an app that worked that way-Deneba Canvas? I don't know, maybe only illustrators who work in both Photoshop and Illustrator would care about this, but I do a lot of it-produce an item in Adobe Illustrator for use in a picture, then copy and paste it into a scanned figure opened in Photoshop, then add shadows and tones. It would be helpful to be able to manipulate the vector art as vector art in Photoshop.

ya, you have to open it up in ai like the above post said if you want to edit it. but also one of the advantages to smart objects is that when you resize it, the quality remains unchanged as long as it is equal to or smaller than the original size. for example, if you design a button in illustrator, then you put it on a web page in photoshop and scale it down and hit enter, you can always make it bigger (up to original size) without losing quality. if you did this with a regular raster image you cannot size it up without losing quality.
the reason you cannot edit the vectors in photoshop is that vector and raster are different types of files. it's kindof like trying to edit videos in photoshop. just wont work. it'd be cool if you could though because i am in your shoes too.

How to convert all white - alpha for vector image?

I'm attempting to make a new font. Currently I've been saving all the png -> vector images that I work with as .AI files, so that I can import them into my font program later, and they open fine in illustrator. The problem is, I usually save my vector images with a white background instead of alpha. Now, I need to replace white with alpha, but I can't find a magic wand in illustrator . Any help?

function(){return A.apply(null,[this].concat($A(arguments)))}
I only knew the most fundamental differences between raster and vector: that raster images are saved in dots while vector images are saved in, at the simpliest, lines.
Not "dots"; pixels. Pixels are simply color values. That's all. Raster programs arrange color values in a rectangular grid of same-size rectangles (usually squares).
Not "lines"; paths. Paths are discrete individual objects. Paths are stacked, independently moved, freely arranged, scaled, filled, stroked, and otherwise manipulated as individual objects.
function(){return A.apply(null,[this].concat($A(arguments)))}
But I'd have thought there was a way to quickly delete the white lines
There is no "vector image" with a background. Where there are no objects, there is no "background." If a path is there, regardless of whether it has a white fill, a white stroke, or fill(s) and/or stroke(s) of any other color or no color at all, the path is there and can be deleted. (Again, there is no substitute for learning to use the program from the documentation.)
Technically, paths are mathematically-defined curves. So even a "straight line" is a path, and is technically a curve. The specific kind of mathematically-defined curve used in programs like Illustrator is called a Bezier curve.
function(){return A.apply(null,[this].concat($A(arguments)))}
I have no idea how hard it is to create a vector image from scratch.
It's not rocket science. Anyone can learn it. But again, you have to learn it. There is no substitute for learning to use the program from the documentation.
function(){return A.apply(null,[this].concat($A(arguments)))}
I myself am mostly a newbie in both hemispheres of the graphic design world.
It shows. And there's certainly nothing wrong with that. We all started as beginners. I'm not trying to belittle you: I'm offering you sound advice that will serve as a very valuable shortcut to becoming more than a beginner (if you will accept it) without an unnecessary amount of fumbling around with bad practices.
Just don't ever claim to a client or in a job interview to know anything at all about any mainstream general-purpose vector drawing program (of which Illustrator is just one) until you are proficient at drawing Bezier curves. That's prerequisite. It's lesson one in chapter one. Might as well start there. Start at the correct beginning and you'll know all the answers to the questions you have asked in this thread. Your understanding of "background" and things like why a region with no objects is not the same thing as an alpha channel in a raster image will come very early if you just start at the beginning. You've got to learn the lay of the land. Start at the beginning.
function(){return A.apply(null,[this].concat($A(arguments)))}
In any case, I use a program called vectormagic that does the work for me pretty well, so you might want to check it out.
Trust me; I'm familiar with it. It's just another autotrace program. I know what it does. I know how "well" it does it. Everything I said in the previous post stands.
Vector drawing programs are not the kind of program you learn by just launching it and poking around. Not if you want to avoid endless confusion and frustration. Asking random questions in an online user forum (in which wrong "answers" are just as common as right answers) everytime you encounter a point of confusion is just as inefficient. Read the documentation.
