A filtragem de dados é essencial ao trabalhar com informações. É difícil imaginar ferramentas analíticas sem tal opção. Na maioria das vezes, filtros e classificação são usados para: acessar dados rapidamente; tornar dados mais fáceis de usar; edição facilitada de dados; estruturação da informação. ...

Images with transparency are often called images with an alpha channel. What does this mean? The alpha channel contains information about partial or full transparency of the image. It is mainly used in computer animation. RGB images can have up to 24 alpha channels. Each of them contains information about the transparency of a part of the image. Managing these channels can make parts of the image transparent at the right time. This creates an animation effect. The most common raster formats of images with support for transparency: PSD - the native format of Adobe Photoshop. Supports full and partial transparency; TIFF - most often used to store scanned images, because it allows you to store information about the great depth of color. This quality has made the format of tiff popular in printing. Supports partial and full transparency; GIF - this format is most popular in the Web graphics, because the file has a very small size. Allows you to ...

In FastReport, the Matrix object allows us to filter data. This is one of the most popular functionalities and many users like to use it. However, sometimes filtering the original data is not an option. Let's take a look at the matrix below. As you can see, these are sales statistics by employees for 5 years. There are no statistics for Steven Buchanan employee for 2011, 2012 and 2015. This means that Steven will disappear from the matrix if we filter the matrix by year and count out 2013 and 2014. To complete the picture, you need to count all employees, even if they did not have sale ...

"Drill Down" or "deepening into data" is a concept with many sides, which can refer to actions in tables or in something else that encapsulates information. And plain and simple, it's a drop-down list! One of the most important operations is Drill-Down, for example, in OLAP with cubes, and, in principle, many places. After all, it greatly simplifies the analysis of information. A "careful dive" into the layers of data. Let's "take a closer look at the data"! This is normally done by clicking on the data we want to drill down into. You can do a drop-down list in FastReport VCL and this is the feature we will talk about in this article. About Drill-down properties in FastReport VCL and its connection: The group header itself has a DrillDown property ("DrillDown" item on the menu). When DrillDown is enabled, it will be possible to make the group interactive. In simple terms, the group will begin to respond to a mouse click in t ...

Each report designer encounters a situation where it is necessary to arrange controls at the same level, or to stretch a group of elements at once. It is necessary to adjust each member to each other. It takes time, and sometimes nerves. In previous FR VCL versions we were offered a grid that facilitated the positioning of objects, as well as lines that help to expose the object in parallel to others. In Fast Report VCL 6, there is another tool for positioning objects - Guide line. It allows you to add to the grid arbitrary vertical and horizontal lines, which help to align objects in parallel. But their main feature is that the objects are attached to the boundaries of lines. By moving the attached lines, you can scale or move objects. Thus, to stretch a whole group of objects, we need to move just one line. These guide lines are visible only in the report designer. They can be added, deleted, moved and hidden. To enable Guides (guides) we open the View menu ...
