W3C liability, trademark, document use and software licensing rules apply. Abstract This specification defines the features and syntax for Scalable Vector Graphics (SVG), a language for describing two-dimensional vector and mixed vector/raster graphics in XML. Status of this document The Scalable Vector Graphics (SVG) 1.0 specification is still in the Candidate Recommendation phase. This new draft specification is being published to reflect minor changes to the specification and editorial updates resulting from implementation feedback. The SVG Working Group (Members-only) considers the specification to be stable and encourages implementation and comment on the specification during this period. The Candidate Recommendation review period ends when there exists at least one SVG implementation which passes each of the Basic Effectivity (BE) tests in the SVG test suite. The implementation status of SVG is already very good, and at this point, most of the test are passed by one or multiple implementations, but as yet the exit criteria have not been met. It is anticipated that implementation status will be such that the exit criteria will be met in approximately one month. Please send review comments before the review period ends to [email protected]. Should this specification prove very difficult or impossible to implement, the Working Group will return the document to Working Draft status and make necessary changes. Otherwise, the Working Group anticipates asking the W3C Director to advance this document to Proposed Recommendation. This is a W3C Working Draft for review by W3C Members and other interested parties. It is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to use W3C Working Drafts as reference material or to cite them as other than "work in progress". This is work in progress and does not imply endorsement by, or the consensus of, the W3C Membership. This document has been produced as part of the Graphics Activity. The authors of this document are the SVG WG members. The editor is Jon Ferraiolo. A list of current W3C Recommendations and other technical documents can be found at http://www.w3.org/TR/.

  • Using GIMP to Create an Artistic Regional RPG Map – Part 5
    Using GIMP to Create an Artistic Regional RPG Map – Part 5 This tutorial series is an updated and revised edition of an original tutorial created by RobA for the Cartographer’s Guild (www.cartographersguild.com). Updates and revisions to the instructions, along with new screenshots, were created by Megan Wiseman (“wisemoon” on Cartographer’s Guild). Part 1 gave instructions on how to create the basic landmass outline for your map, including some ideas on how to randomly generate a landmass shape if you don’t have a sketch to start with. Part 2 gave instructions on how to color your ocean/sea, and how to color your landmass with textured grass and dirt. Part 3 gave instructions on how to create mountains and forests on your map. Part 4 gave instructions for how to create rivers and lakes on your map, and also showed you how to create cities and roads. This part of the tutorial will show you how to label your geographical features and cities. Then we’ll show you how to create a nifty title for your map. You can create a legend for your map in the same basic way you create the title. You can also add a compass rose. We’ll finish it off with a simple border. Adding Labels to Your Map Every map has labels for various geographical features, as well as labels for cities, towns and other settlements. Most of the horizontal text labels will be made using the text tool, just like the city icons were done in Part 4.

  • Decomposing Images Into Layers with Advanced Color Blending
    Pacific Graphics 2018 Volume 37 (2018), Number 7 H. Fu, A. Ghosh, and J. Kopf (Guest Editors) Decomposing Images into Layers with Advanced Color Blending Yuki Koyama and Masataka Goto National Institute of Advanced Industrial Science and Technology (AIST), Japan Boom layer Top layer (N/A) normal hard-light multiply Input image Decomposed layers Edited image Figure 1: Our method decomposes an input image (Left) into layers that can reproduce the image by composition with advanced color-blend modes such as hard-light and multiply (Middle). Users can specify the color-blend mode and desired color distribution for each layer, as well as the number of layers. Output layers are useful for non-trivial image manipulation such as lighting-aware color editing (Right). Input image courtesy of David Revoy. Abstract Digital paintings are often created by compositing semi-transparent layers using various advanced color-blend modes, such as “color-burn,” “multiply,” and “screen,” which can produce interesting non-linear color effects. We propose a method of decomposing an input image into layers with such advanced color blending. Unlike previous layer-decomposition methods, which typically support only linear color-blend modes, ours can handle any user-specified color-blend modes. To enable this, we generalize a previous color-unblending formulation, in which only a specific layering model was considered. We also introduce several techniques for adapting our generalized formulation to practical use, such as the post-processing for refining smoothness. Our method lets users explore possible decompositions to find the one that matches for their purposes by manipulating the target color-blend mode and desired color distribution for each layer, as well as the number of layers.

  • Layer Blending Modes
    Layer Blending Modes lend Modes can be used to tell layers how to interact with layers beneath them in dif- ferent ways. By setting Blend Modes you can make paint darken paint below, tint it, or oth- erwise adjust it. ArtRage provides a number of Blend Modes, including the standard ones from Adobe Photoshop and some of its own. The default Blend Mode applied to each Layer is “Normal”, which means that paint will sit on top of paint on the layer beneath and cover it like normal paint on a surface. To use layer blend modes you have to have two or more layers. The blend mode will react with the layer below it. For this tutorial I will be using an image with two layers. The blending mode will be applied to the top layer and we'll look at the way they both interact. The background layer is a picture I took on a holiday in one of my favourite places in Bel- gium. The one I will use for the layer modes is made of some grayscale and colour sam- ples. The tint mode takes the color of the paint on your lay- er and tints the paint underneath it. In this example the blue sample has applied a blue tint to the Photo beneath. Use this mode if you want to apply color to something in gray scale, or tint the color below with a new color above. The highlight blend lightens paint beneath it, allowing you to make paint brighter by applying paint above it without washing it out to plain white.

  • Blend Modes Explained
    Search PHOTOSHOP TUTORIALS Beginners | Intermediate BLENDING MODES NOTE (The majority of the following information can also be found in the program's Help files, and I take no personal credit for writing it. I have converted it to HTML and posted it here simply as a convenience for my visitors, and to supplement other content.) Please give the image samples a few extra seconds to download, this is a long page. But the information needs to be all on one page so you can compare the Blend Modes against each other. Read the following while you're waiting... Layers You use layer blending modes to determine how the pixels in a layer are blended with underlying pixels on other layers. By applying specific blend modes to individual layers, you can create a wide variety of special effects. NOTE There is no Clear blending mode for layers; as is found in the 'Stroke' filter for instance. In addition, the Color Dodge, Color Burn, Darken, Lighten, Difference, and Exclusion modes are unavailable for Lab images. Painting & Editing Tools The blending mode specified in the Options palette for each tool controls how pixels in the image will be affected by tools. It’s helpful to think in terms of the following colors when visualizing a blending mode’s effect: The 'Base color' is the original color in the image. The 'Blend color' is the color being applied with the painting or editing tools. The 'Result color' is the color resulting from the blend mode used. Blend Mode Descriptions Page 1 These mode types are based on the latest version of Photoshop, but their effects are universal in all versions.
