Vector graphics are graphics in which the image is represented in a mathematical fashion. What this allows one to do is to zoom in an image to infinite precision. They are ideal for situations in which an image might be used at various resolutions and dimensions. Raster graphics are of a fixed dimension, somewhat like a grid pattern with specified values at ...

Any time a format isn't available in the Save As dialog, it means that format is invalid for the document in the state it's in. There's no such thing (as Lese and cwedge point out), as a 32-bit (or 16-bit) jpeg, nor a duotone, Lab or 1-bit bitmap jpeg. Photoshop versions prior to CS5 would simply not show jpeg as an available option for 16-bit images, which ...

.ai Contains: Native Illustrator content (unflattened) - used when file is reopened in Illustrator PDF 1.4 content (unflattened) - used when file is opened or placed anywhere else* *In the Illustrator Options dialog that appears when you save a native .ai file, a checkbox called Create PDF Compatible File, marked on by default, determines whether the ...

An .SVG file IS a source file. It isn't layers in the Photoshop/Gimp sense but it absolutely can be picked apart. Use an SVG editor - that would be Illustrator or Inkscape. Alternatively, if you want to get real crazy you can open the .SVG in any text editor and look for the values you want to change which for colors would be in Hex format #nnnnnn

SVG is scalable, if you have a vector-graphic that is a clear advantage. For pixel-graphics PNG is better. A downside is, that the Internet Explorer supports SVG only with the coming version 9 (before with plugin). Mobile browsers may also have limited support for SVG. EDIT: As ClemDesm points out, older IE-versions don't support fully transparent PNG, ...

If you're using a version of Photoshop earlier than CS6 and your document is 16-bit, or if it is in a color mode such as Lab or multichannel that isn't supported in jpeg format, then jpeg won't be offered as an option on save. Image > Mode > RGB Color Image > Mode > 8 Bits/Channel Then Save As. One of the much-welcomed features in CS6 (or ...

@Pearsonartphoto already puts it nicely. In an effort to find the shortest possible definition that is still correct: Vector graphics are a collection of geometrical elements (primitives like circles, squares, triangles... as well as polygons and curves) that you can enlarge to any size. Raster (Pixel) graphics is a collection of coloured dots. You can't ...

I would say PNG simply for the fact it seems to be a more accepted format than SVG.

(that's Illustrator on the left, Photoshop on the right) Raster images are just grids of pixels, like what comes out of a digital camera or a scanner. The file doesn't know what those pixels mean. Web images and digital paintings are most often raster. Adobe Photoshop, GIMP, Krita, Corel Photopaint and Pixelmator are primarily raster (some have a few ...

My first, second and third answers to this question would be "Find a different printer, because the one you have is incompetent." There is no grande format equipment made that requires jpeg as input. Typical spec, this one from the Fuji website: Formats All popular desktop formats including PostScript 3, EPS, TIFF, PDF, both RGB and CMYK color ...

There's a great deal of opinion and frankly false information circulating on this topic. It's pretty safe to say that EPS, being Postscript based, is an obsolescent format just as Postscript is obsolescent. It served the community well back in the day, but it's long been overtaken by PDF and AI. EPS has almost no place in a modern graphics workflow and is ...

A PHP script on the server (which is what the URL causes to be run) returns a response to the browser which contains the header Content-Type: image/jpeg so the browser knows that what is returned is a JPEG image and displays it accordingly. The browser uses the response headers to determine what to do with content. Client operating systems may behave ...

And EPS stands for Encapsulated Post Script and isn't a file format as much as it is a file container. An EPS can all sorts of data. It's been a while since I've done much AI work, but I believe you can save it as a more generic EPS, which any other decent DTP application with PS support should be able to open, or you can save it specifically as an AI EPS, ...

An answer from a different perspective: In our design shop, when we create a logo with text, the original is saved as an AI with live fonts. When the logo is approved by the client, the letters are turned to outlines (so the logo can't be screwed up in another application by having a font missing) and we save that as the EPS version. We always know to ...

Definitely use PNG for a website. SVG is simply not sufficiently widely supported and it has few (if any) significant benefits over PNG for a flattened export. That said, keep all of your working copies in SVG.


5

The simple answer here is use both. The fact that you've named SVG as an option, means we can rule out photo graphics as an intended use case - because SVGs are only good for line-art graphics such as logos, icons and clip-art-like illustrations. If you are considering this choice for photo graphics, there is no choice; PNG will probably always be better. ...

To add to DA01's excellent answer and to provide additional context, OpenType comes in two flavors: TrueType and PostScript. So way back in the day, when Adobe created PostScript, they defined curves in a certain way mathematically. PostScript became wildly popular because it could accurately take things on screen and print them onto paper and it could ...

NOTES: Inkscape would be an example of a Vector Graphics editor, while GIMP/Photoshop/Paint.NET/etc are suited to editing raster images. Ever notice that as you zoom into an image, the quality gets lower? That's a raster image. A raster image is like the one your digital camera takes. They are usually in the formats JPG (lossy), GIF (lossless), PNG (my ...

You probably have the color mode set to 32-bit per channel, but it's hard to tell without knowing what the 5 displayed formats are.

In our graphic design shop with an emphasis on print production, eps is still very alive and well and we follow the same workflow: .ai files are the "native" file format and can only be opened by Illustrator. We keep fonts as fonts in .ai files. This is the master larger file for any project, often with multiple hidden layers containing development artwork ...

What specific advantages or disadvantages can be found in the various font formats in today's technological setting?? As you stated, today's main advantage is with OpenType being able to support a much larger set of glyphs as well as other things like alternate characters and automatic character swapping. Should I be avoiding Type 1 and Type 3 ...

Designing a graphics for a header is not just designing the image, but knowing how the header will look overall. If you provide only the image, there is a chance the other person making the website put just a tini little version, or a deformed one for example. So the first step is to prepare a canvas simulating diferent screen devices, let's say: 1920 ...

I have not seen it mentioned and you also said community so my answer would lead more to a forum based choice instead of a CMS. CMS may be a better solution in regards to a preexisting WordPress site with the installation of BuddyPress/bbpress but I have not had any experience with attachments for it. A free solution also in regards to a community would ...

Quick and easy workaround is to Save a Copy. Hold down Option/Alt when you choose Save As. If there's something about the image specifically preventing a format choice, the save as copy will remove that aspect of the image. Although.... There are very few times when you actually want to save as a jpg and not use Save for Web. Be aware, jpg is a lossy format ...

The tricky thing about favicons is that they are tiny (well, while the classic favicon was 16x16 px, you can now use 24x24 px. Still quite small). Because of this, and just as it happens when working with small icons in general, you need to create a version of it pixel by pixel. Scaling just doesn't do. Check this related question: Tools or methods for ...

For saving the file always use native file formats like EPS for Illustrator. That's for your file back up. For print it is important that you use a CMYK color mode. Now-a-days PDF, TIFF and EPS are used for printing. PDF is increasingly used now among designers. TIFF is used with ease since color management is possible but ask your printer if they accept ...

As long as you are using shapes and the pen tool in Illustrator it really doesn't matter. Letters that are converted to paths are fine too. Not sure about the other tools. Since you are creating vector graphics with those tools (when using Illustrator) they can be enlarged infinitely without loss of quality. Save your files in EPS, AI, PDF or SVG. Those ...

2 bit images 2 bit images are not 2 color images. 2 bits would store 4 colors. Currently the png file format allow several bit depths http://www.w3.org/TR/PNG/#11IHDR. Some good years ago the CGA color mode for monitors displayed a Cyan Magenta Black and White images. Those were 2 bit images. You could convert them to Red Green Black and Yellow. That ...

Your Color Mode (Image > Mode ) could be set to something like Lab or Duo-tone, both of which won't save as JPG.
