![]() Reduce the number of contours and/or inter-contour spacing to minimize file size.Crop/expand figures as needed so to minimize blank space around the figure.Add/manipulate text and annotations in vector format – change fonts as required.Import the file into software that can edit vector graphics files (Adobe Illustrator, Inkscape).From the NMR program, output the spectrum in scalable vector format (usually PS or PDF).If a full spectrum is to be shown, minimize blank space, and ensure that peak labels do not overlap.This usually means zooming-in on a region of interest, at the expense of the full spectrum Be sure to simplify the figure to focus the reader’s attention to the spectral features of interest – do not expect a reader to interpret the spectrum on their own.Use black and white unless color is necessary to illustrate a point.Figures should be prepared separately, including annotations/labels, then embedded intact into a text document – do not try to edit a figure within a word processing program!.When possible, prepare figures using vector format, not raster/bitmap.Do not allow figure elements to clash/overlap (annotations, lines, images, legends).Use sufficiently large text so that it can be clearly read when printed at the intended size.Image manipulation: Graphic Converter (Mac), GIMP (LINUX), Photoshop.Alternatives: LibreOffice Presenter, Keynote, Inkscape.Graphics anotating: Powerpoint, Illustrator.The resolution of the image is set by the number of pixels (e.g., 150 dpi) Raster or bitmat format: Images composed of a grid of pixels in which each pixel has a different color.This format can be scaled infinitely with no loss of resolution. Vector format: a graphics format in which images are produced via commands (draw line from x1,y1 to x2,y2).Now gracefully handles the situation of not having enough background area selected to extract gradient information.Preparing scientific figures for manuscripts, presentations and grant applications Glossary.(Please convert other images to one of these modes to use the plug-in.) Disabled the plug-in for images in modes other than RGB and. ![]() Revised licensing system to be more robust (permanent keys will not require re-entry.) Ported plug-in to work on both Windows and Macintosh computers. Made registration email address case-insensitive.Ĭhanged registration reminder (nag screen) to only show up once per day.įixed registration issue on PowerPC-based Macs. Fixed the “strength” parameter reversal on the Mac version. Ported plug-in to work on 64-bit Windows Photoshop installations (XP 64 or Vista 64). Ported plug-in to work in 64-bit mode with Photoshop CS5 on Mac OS X 10.6 (Snow Leopard). The Mac version is now also signed with an Apple Developer ID and notarized by Apple, eliminating security warnings on MacOS Catalina and later. Settings, including license information, are now saved in a manner that is compatible with both Photoshop and Affinity Photo. (Mac-only update) Apple M1 silicon Mac compatibility.Īffinity Photo compatibility. Updated the MacOS and Windows installers to add installation for Affinity Photo 2. They can sometimes be made to work, but tens or even hundreds of background points must be marked for the tool to build an adequate mathematical model of the gradients.įor more details, check out the GradientXTerminator tutorials and manual.Įnabled 32-bit image processing for Affinity Photo 2. But for complex gradients that arise from multiple stray light sources and flat-field calibration errors, these tools are less than convenient. This was a great leap forward and produced much improved results. More recently, tools have become available that allow the user to tell the software what parts of the image are background by placing small markers on the image. ![]() A bright galaxy in the center of an image, for example, would “fool” the software, resulting in a dark halo around the galaxy. This was usually detrimental, since the software could not easily differentiate between background areas and actual objects. In the past, image processing programs have tried to correct gradients by automatically determining how they affected an image. Gradients, whether caused by light pollution or image calibration errors, have always been a problem with amateur astronomical imaging. And assuming you already use Photoshop in your work flow, you may now have one less program to transfer your image into. It easily tackles large-scale gradients from light pollution, but can also handle vignetting and even tricky edge, corner, and circular gradients that are very hard to deal with otherwise. It can process 32-bit, 16-bit, or 8-bit images, grayscale or RGB color. ![]() GradientXTerminator is a gradient removal plug-in for Photoshop and Affinity Photo that is fast and easy to use.
