How to Customize Precision during Vectorization

The automated conversion of a raster image made up of pixels into scalable vector graphics is a complicated process that often has mixed results. The accuracy of the output vector depends on several things, including the quality of the input raster, on how detailed or “cleaned up” of noise is the image, on conversion algorithms etc. Common problems are the incorrect shape and color rendering.

To prevent the issues that might come up during vectorization, reaConverter’s latest edition offers several ways to customize the raster-to-vector conversion process. Opting for an outline or centerline algorithm and ignoring raster data when the input vector includes mixed vector-raster content are among the available possibilities.

Ignore Raster Data when Converting from Vector Formats

Vector files are sometimes complex layered image structures that can contain both vector and raster data. For example, you can have a detailed scalable map made up of lines and curves also including raster representations of some map elements, such as an aerial photograph or satellite image.

When converting PDF, EPS, CDR, XPS, SVG and other vector formats with mixed raster-vector content to raster formats such as JPEG or PNG, a fair representation of colors and quality will be ensured. But when you convert to another vector format, image quality might become an issue.

How to Set Default Units when Converting from Raster to Vector DXF/DWG

Do you have a scanned drawing, a map or some other type of raster image that you would like to turn into a DWG or DXF vector? Supporting most existing raster formats as input files, reaConverter makes this process easier than ever and provides you with a handy scaling tool too.
Set DWG/DXF default units
Vectorization can be done using the two available methods: outlining (creating lines / curves along the borders of linked pixels) or centerlining (generating lines / arcs along the center of linked pixels). And because vector files can contain drawings at any scale set by the designer, when you convert from raster reaConverter allows you to pick the desired scaling unit for the output DXF or DWG image. Available options are: millimeters (set as default), inches and pixels.

Convert EPS to PDF Retaining Vectors

Converting a vector image format to PDF usually implies that some of the information used to compress the image is lost and, hence, the quality of the image is affected. However, when you use a powerful converter such as reaConverter, which fits the needs of both professional and amateur graphic designers, you no longer need to compromise when it comes to preserving image quality.

How to Convert JPEG into DXF Vectors

JPEG is the most popular format for storing and sharing decent quality images or uploading them online. But in case you want to process a JPG file via a computer-aided design program such as AutoCAD, you will need to vectorize it. Or, in other words, turn it from a raster file made up of pixels — into a vector file made up of points, lines and curves.

How to Convert AI to PDF and Maintain Image Quality

Have you ever thought of converting an AI vector file to PDF, but were worried about image quality loss? AI is the native format of Adobe Illustrator and is preferred by many graphics designers for storing and editing vector-based drawings. However, handling an AI file might pose some difficulties. Why? Firstly, vector files tend to be very large in size. So transferring them by e-mail, for example, might be an issue. Secondly, viewing and editing such files requires having Adobe Illustrator or a similar advanced graphics editing software installed on your computer. These types of programs are difficult to use for non-professionals and are quite expensive.

Do you have an AI, a CDR or some other type of vector file that you would like to convert to a different vector format? Perhaps you have CAD vector format files, such as DWG, DXF, PLT or Windows Metafiles: EMF/WMF and you would like to convert them to another accessible vector formats such as SVG or PDF? In any situations above, reaConverter allows you to process this operation fast and easy through its vector to vector direct conversion feature.

How to Convert SWF Files to Images?

How to extract raster images from SWF file?

The SWF format is one that you’ll find commonly used for browser games, vector animations and other types of multimedia that imply video, sound and/or user interaction. Initially developed by Macromedia, SWFs are currently Adobe Flash files and their name is an acronym for ShockWave Flash or Small Web File.

SWF files can contain a collection of images, including both vectors and bitmaps, as well as ActionScript content — a scripting language that facilitates user interaction. A SWF file can contain from few images to more than a hundred pictures with text, animation, and scripts in various combinations. For example, one page with text and several raster images inside it. Extracting all raster images by converting a SWF file to one or more image files can be a tricky operation and requires using a software program that can process multi-page image files, such as reaConverter.

Convert NVA eBooks to More Accessible Formats: PDF, JPG, TIF, PNG

NVA is a new and popular file format used particularly for storing ebooks and associated with a piece of software called NVA Reader. This program is optimized to work on all types of platforms, including Windows, Mac, Nexus phones and tablets, iPhones and iPads, the Samsung Galaxy series etc.

Some of the main advantages of using NVA files are the possibility to select, highlight and underline text, make notes and add bookmarks. NVA files simulate the appearance of the print book really well and they preserve the structure, format and objects on each page. They also include handy search tools and features that facilitate sharing notes or quotes on social networks.

But if you have just downloaded or received by email an NVA file, you might notice it is not compatible with many other programs apart from NVA Reader. In case you want to convert it to a more accessible format, such as PDF, reaConverter can make this happen in a few seconds and without any quality loss. Additionally, reaConverter supports conversion from NVA to raster image formats, such as JPG, PNG or TIFF.

Do I Need GhostScript When I Convert a PDF?

We recently received this question from a ReaConverter user who tried to convert a PDF document into an AI (Adobe Illustrator) image format and was slightly puzzled by a message that popped up before conversion, saying GhostScript is required. He also mentioned a GhostScript driver was already installed on his computer, so he couldn’t figure out why the conversion wouldn’t work.
