Synfig: Introduction to Layers

CH.4 Introduction to Layers

• To create animation on a 'sunrise scene', mountains, the sun, birds, and trees are required.
• In Synfig, a layer refers to different levels on which drawing objects or pictures are placed, stacked above and below each other.
• Layers give the freedom to work with each object individually.
• Modifying layers does not disturb other objects either above or below it.
• Layers can be rearranged, allowing for changing the order in which objects are displayed.
• In Synfig, each individual element is broken down into layers.
• Layers in Synfig are different from other animation software.
• Every element has its own layer.
• A layer represents a single primitive such as an object, outline, or image.
• The upper layer can change the behavior of the layers below it and can distort or modify the layers beneath using effect or filter layers.
• In Synfig, there are different types of layers such as Gradient, blur, or distortion.
• Each layer has its own set of parameters.
• The parameters of a layer can be seen by selecting the layer from the panel and then looking into the params panel.
• Blend mode defines how the image is layered on everything below it.
• In Blend mode, the default setting is 'composite' layer.
• Encapsulation is used for a gradient to be applied only to a single object and not all the objects below the gradient layer.
• Encapsulation means grouping things together.

CH.7 Vim Editor And Basic Scripting

• Gedit is a graphical editor available with the GNOME desktop environment.
• To execute a command, the user types it at the prompt and presses the Enter key.
• In Linux, the output of the command available is displayed on the screen.
• The user executes the commands available in the text file in a sequence.
• All commands available in the text file in a sequence are called shell scripts.

CH.5 Using Pictures in Synfig

• Pictures are used improve the quality of reception in a presentation or animation.
• In Synfig, images can be inserted to give a different look.
• Import -> Image is used to import images.
• CTRL + i is used for importing images.
• In the import image dialog box, select open after selecting an image file.
• To resize the imported image, select the image layer in the layers panel, and two green points on the image will be seen.
• Whenever the image is resized, the image tends to get distorted because aspect ratio is not maintained.
• To resize the image and keep its aspect ratio, encapsulate the layer.
• To encapsulate, right-click on the image layer and select encapsulate.
• Selecting encapsulate by right-clicking on the image layer will add a canvas layer.
• Open the encapsulated layer using the triangle and the image will be visible in the inline canvas
• Selecting the image layer -> to add a new scale layer on top of it.
• To rotate the image: Right click -> New Layer->Rotate->Transform
• By using the rotation duck to rotate the image as wanted
• In synfig, a rotation duck is of green color

CH.10 Working with Tables

• To get the correct information at the right time, the database must perform various operations like inserting data, editing previously wrong data and deleting unnecessary wrong data.
• To insert records into the tables, open the table first.
• Right-click the icon that has the required table name in Tables Pane of the Database Window.
• Right-click on the desired table and select the Open option from the sub-menu visible.
• In Base, the line consisting of field names is known as the heading line.
• In Database view, limited fields are seen and to see the remaining fields Scroll bar is used given at the bottom of the screen
• In Base, below the Title Line, there is a row consisting of empty boxes, which should be filled with appropriate data is known as Data Entry.
• In front of the first field, there is a small box that contains a pointing arrow sign. This box is known as a Record Selector Box.
• The sign in 'Record Selector Box' is referred to as the Record Selector Icon.
• The black pointing arrow icon indicates the current record of the table
• The record pointer icon with flash is the end of the table mark.
• ESC stands for Escape key.
• The pencil icon is an Edit icon.

CH.11 Retrieving Data Using Queries

• A database is a huge collection of data.
• Query is the feature of Base, which can be used to retrieve a specific set of information from the database.
• The user can retrieve data according to their criteria.
• The reason behind using a Database Management System is to design a query, use the queries as and when required, and for storage purposes.
• Query means asking questions, inquiry, or performing analysis.
• In Base, to query is to ask questions about the information in the database.
• Query means asking questions, doing inquiry, performing analysis.
• Through a query, one can tell Base to display the exact fields and records.
• A query is a set of rules for fetching information from a table, or from several tables at once.
• The result of a query is in the form of a table.
• The result of a query is in the form of table which consists of a set of rows and coumns.
