You can change the name of a layer by clicking on it in the table. The current layer is also shown in the layer popup in the Toolbar. The current layer is indicated by a small "+" to the left of the layer name. The table below the size/coordinate controls shows the drawing's layers. (This can be useful for matching the origin to an imported graphic.) After selecting "Click Sets Origin", the next click in the drawing area will set the origin to that point. You can also use the "Click Sets Origin" option to set the origin to a point in the drawing without having to know its numerical location. You can center the origin vertically and/or horizontally in the drawing. The popup menu below the origin distances gives several useful options for setting the origin. The x/y origin of the drawing's cartesian coordinate system is displayed as the x and y distances from the upper left corner of the drawing. If you've imported a large graphic and want to match the size of the drawing to that image, the popup menu below the origin fields has a "Match Size to Contents" option. If you want to change the document size while keeping the origin in the center of the drawing, you can select the "Center origin when resizing" checkbox before editing the size of the drawing. Document size is normally expanded down and to the right. However, selecting File->New will present a page setup dialog and the initial size of the drawing will be one page using that setup.
The size of the drawing is set without regard to page setup for eventual output. The size of the drawing and the x/y origin are shown using the desired measurement system. Using US English, the actual units are inches and the scale is 1:48 or 1/4"=1'-0". Using metric, the actual units are centimeters and the scale units are 1:50. Measurements in LXFree for Java can be either scale or actual. LXFree for Java uses a cartesian coordinate system. The show title also appears in the page header when a report is printed. The basic title information is used when a title block is inserted into the drawing. The bottom section edits the document's drawing layers The middle section sets up the size and coordinate system of the drawing. The top section contains basic title information about the drawing. See the example below: import Document tab has three sections. The first thing we can do is to create an ArrayList and copy all the array elements into it. The topmost alternate of the dynamic array is the ArrayList class of collection framework that can store any number of elements, and grows dynamically. In this article, we will learn to resize an array by using some built-in methods such as the arraycopy() and copyOf() functions and some custom codes. It is a fixed-size container, which means if an array is of a 10 size, it can only store 10 elements - this is one of the limitations of an array.
