Illustrator is a vector based program that can export raster images.
It is question for Photoshop and Illustrator developers, which tool is from which app but Illustrator have Photoshop raster filters, that's for sure.
Illustrator lacks the extensive raster-based editing tools found in Photoshop, such as advanced photo retouching features and filters specifically designed for pixel manipulation. While Illustrator excels in vector graphics and illustration, it does not offer the same level of functionality for editing photographs or raster images. Additionally, Photoshop includes more sophisticated layer effects and blending options tailored for pixel art.
You can open an eps file in either Photoshop or Illustrator, it helps to know if it is raster (use Photoshop) or vector (use Illustrator).
raster
These are different applications. In general given that Illustrator is a Vector based graphics program and Dreamweaver is a Web editor using raster files for most graphics / images (Flash based files being an exception), the two programs will never have a true round trip editing compatibility.
Photoshop is raster based but you can work with vector objects in Photoshop. Why is raster based is question for founder Mr. Thomas Knoll not for public because we can not answer this question. Maybe because this world need raster based software.
Photoshop for raster images. Illustrator for vector images. These are the industry standards.
You have to use programs which support vector graphics and raster graphics, so you can save them in what format you would like? ex: Adobe Illustrator, CorelDraw you can use...
Adobe Illustrator does not have resolution tool. You can manage resolution settings from Effects > Document Raster Effects Settings.
Yes, partially. PDF encodes fonts and EPS graphics that are vector based. It also encodes images, in JPG format for example, which are raster based.
Illustrator is a vector based program. Photoshop is well... for photos mainly. I've used both hand in hand to create awesome graphics utilizing the 3D capabilities in Illustrator. Vector graphics are basically line drawings that can be used at any size without distorting resolution as would happen in Photoshop.
In Adobe Illustrator, resolution refers to the quality and clarity of images and graphics, typically measured in dots per inch (DPI). Unlike raster graphics, which depend heavily on resolution, Illustrator primarily uses vector graphics that can be scaled without loss of quality. However, when exporting or printing designs, it's important to set an appropriate resolution to ensure the final output meets desired quality standards, especially for raster elements. For print, a common resolution is 300 DPI, while screen displays often use 72 DPI.
