How to Set Pen Width during Conversion to PLT

PLT is an image format associated with plotters — a type of printing devices that use vector graphics as input files, as opposed to regular printers, which can only print raster images. Plotters can be of different kinds, including pen plotters — printing devices using a pen to draw lines and curves on paper, and cutting plotters — using knives to cut shapes into paper or other types of materials.

Files with the PLT extension usually store maps, posters, detailed designs of machines and other types of monochrome or full-colored graphics. PLTs can be created using computer-aided design software, such as AutoCAD and Adobe Illustrator. Or they can be obtained via conversion from other image formats. The main advantage of PLT over other graphics extensions is that the image can be sent directly to the plotting device.

How to Convert EPS to CMYK

EPS in CMYK

EPS (Encapsulated PostScript) is a vector graphics format particularly associated with Adobe Illustrator, but also compatible with other graphics design software, such as Corel Draw. The format uses the PostScript page description language and includes or “encapsulates” a low-resolution preview, which can be displayed by some programs.

Printing EPS files requires a machine which supports PostScript. For best results in terms of rendering colors and shapes from screen to paper, EPS images should be converted to CMYK color space before printing. In other words, the combination of colors used for representing the image should be changed from the primary colors of light — Red-Green-Blue (RGB), which is typical for TVs, computers and other types of backlit monitors — to the primary colors of pigment — Cyan-Magenta-Yellow and Key/Black, which is more suitable for the printed paper.

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.

Converting 3D STL Models to DWG

There is a variety of 3D graphics formats available out there and they can be created using quite a few types of specialized programs. From Autodesk software to Blitz3D and QuickDraw to Blender, there is a long list of software using over one hundred types of 3D output formats.

However, not all enjoy a lot of popularity and some provide more advantages than others. For this reason, converting between 3D extensions might be a great way to improve the accessibility of your files while at the same time preserving their quality content intact. And it can be done in no more than a few clicks using reaConverter’s latest edition.

For example, conversion from STL to DWG formats can not only be done fast and easy, but also includes a series of handy customizable features. STL is a computer-aided design (CAD) 3D format used in model prototyping through stereolitography, 3D printing and computer-aided manufacturing. While supported by several software packs, STL enjoys less popularity than DWG, which is probably the most widely used format for CAD modeling. A native format for Autodesk software, DWG is supported by most CAD programs, including AutoCAD, Caddie, IntelliCAD and many others.

How to Convert Multi-Layered PSD Files to Multi-Layered SVGs

Multipage PSD to multipage SVG

PSD is a popular format for storing multi-layered images created or edited using Photoshop software. The main advantage of using the PSD extension is that images remain easily editable, as their layered structure allows users to add or change various elements and features, including image effects, transparencies, color adjustments and many more.

To increase accessibility and ease of transfer, PSD files are usually converted to more widely used raster formats, such as JPEG or PNG. This type of conversion, though, implies flattening the image, which means no major editing is possible afterwards. And this might pose problems at times.

The hassle of realizing you still need to make corrections to a PSD image that has already been flattened can be easily avoided by converting to SVG (Scalable Vector Graphics) in the first place. This extension allows you to preserve the image layers and defines the graphics in XML format. SVG also supports animation and lets you index, search or compress the image.

How to Convert WMF Files to JPEGs

”Someone recently sent me a WMF file attached to an e-mail. Is it safe to open it on my computer? What kind of file is this and can I use reaConverter to convert it to JPEG?”

A message including this question was recently received by our Technical Support staff and, since other people might experience similar problems, we thought a blog post on this topic would be helpful.

How to Convert JPG to Lossless TIFF

Professional photographers or image editors often have mixed feelings about the use of JPG. On the one hand, they like this format because it doesn’t take too much space, it is easily compatible with any image viewer you can think of, on any type of device (including smartphones, tablets etc.), and it is the default format used by all image sharing websites, from Google to Facebook.

3D Rotate STL Files During Conversion

XYZ axes

STL is an extension attached to 3D images that use Stereolitography, a technology for creating prototypes or patterns through 3D printing. STL files contain a surface representation of such models and are created using computer-aided design software. There are only a few programs that can open STL files, so for improving accessibility the best option is to convert STLs to more popular extensions, including PDF, CAD document or other vector formats.

How to Create SVG with JPEG compression and Alpha-Channel

SVG + Alpha Channel

While most people describe SVG as a vector format containing vectors, animations or interactive graphics and supported by the largest part of web browsers, few know that SVGs can also store raster images. And the best part is that these raster images can handle alpha-channel and JPEG compression, which makes SVG a great alternative for the larger-sized PNG.

SVG is also a better alternative than WebP, JPEG2000 or JPEG-XR when it comes to web programming, as it is supported by Chrome, Safari, Internet Explorer 9+ and Firefox — thus covering all major browsers.
