• SCI Drawing Knowledge: Bitmap & Vector Graphics

  Mar 20, 2025

  When drawing scientific illustrations, we often face the choice between bitmap and vector graphics. This article will focus on exploring their definitions and differences for reference.   1. Image Types and Definitions Vector Graphics: Composed of mathematically defined curves, with anchor points and paths as their basic components.     Bitmap Graphics: Also known as raster or pixel graphics, they are composed of individual pixels. When magnified, it becomes evident that the image consists of tiny square pixels.     2. Image Types and Resolution Vector Graphics: They are resolution-independent, meaning they can be scaled to any size and printed at any resolution without losing clarity. Bitmap Graphics: Composed of pixels, so when an image is enlarged, the pixels also get bigger. Since each pixel has a single color, enlarging a bitmap image results in the well-known pixelation effect.   3. Image Types and Color Representation Bitmap Graphics: Capable of displaying rich and detailed colors, making them ideal for realistic images of natural objects. Vector Graphics: Due to mathematical constraints, they have limited color representation and cannot effectively depict realistic objects. Instead, vector graphics are often used for icons, logos, illustrations and other simple, clear designs. In the following images, you can see that bitmap graphics display a wider range of colors.   Bitmap Graphics Vector Graphics   4. Image Types and File Formats Common Bitmap Formats: bmp, pcx, gif, jpg, tif, psd of photoshop etc. Common Vector Formats: AI, EPS, SVG (AdobeIllustrator), dwg, dxf (AutoCAD), cdr (CorelDRAW), etc.   5. Image Type Conversion Vector graphics can be converted into bitmap images using graphic design software. However, converting a bitmap image into a vector graphic requires complex and extensive data processing, and the quality of the resulting vector image may vary significantly.

• SCI Drawing Knowledge: An Introduction to Cover Layout Using the RSC as an Example

  Sep 24, 2024

  A cover article is a way for every scholar to recognise his or her efforts and research results. Scholars generally pay more attention to the cover. When designing a journal cover, the first thing we need to consider is the layout (size), which is usually shown on the journal's website or in the editor's invitation letter. Let's take the cover of a RSC journal as an example, and discuss with you how to deal with the layout issues in the cover design process. The figure below shows the cover invitation letter for RSC journals, which is divided into two cases: Cover artwork and Back Cover artwork. Let's first focus on Back Cover artwork, generally speaking, the size required by Back Cover artwork is 188mm wide x 136mm high, that is to say, we need to submit the final cover manuscript to the editor, it needs to be such a size (layout). There are 4 details we need to pay attention to here: Firstly, there will be a 168mm wide x 166mm high safe area included in the total size of 188mm wide x 136mm high, we need to put the most important content into this safe area. Try to avoid important content in the outermost 20mm, such as molecular formula, text, key structures, etc. Secondly, the cover image should not be too empty or biased to one side, as shown in the picture below, which is a typical substandard work. Secondly, the colour of the half-ring logo will be specifically adjusted by the editor according to the Cover artwork we submit, and we can make it without having to think about it during the production process, as shown below.
