- | Launch by clicking the Writer icon and you will get a blank page. For this magazine column, I put the heading into Bold 24-point text using the default sans serif font. Sans serif fonts are ones that do not have the ‘tails’ on the letters, they are plain. A capital letter ‘T’ in a sans serif font is just a straight vertical line with a straight horizontal line across the top. In most serif fonts, the capital ‘T’ will have two small horizontal points (‘serifs’) coming to left and right at the bottom of the vertical shaft, and two downward pointing serifs at each end of the crossbar. Font selection is an important part of putting together documents and can easily fill an entire book, but suffice it for now to say that headings in any document are frequently done in sans serif fonts because they scale to large sizes well, and are easy to read at any size. Click the bold letter ‘B’ at the top to make the heading text bold. The ‘B’old button will highlight to show it is active. It can be invoked at the beginning of your typing to make ensuing text bold, or you can highlight existing text and hit the button to Bold the text. | + | Étant donné que Linux est un environnement de développement d'un tel calibre, c'est parfois facile d' |

- | Now, you may have noticed in the screenshot above that, despite my reference to the heading font being bold sans serif, the menu at the top of Writer shows non-bolded Caslon 540 in 12-point size. This is because the body text was active when the screenshot was taken, and it is not bold and is in a serif font. A commonly repeated guiding maxim for font choice for many years has been, “When in doubt, use Caslon”. The Caslon font is a very readable serif font with classic lines that go well with almost any page design, and works well in combination with most other fonts. The serifs are actually helpful in guiding the eye from letter to letter while reading, making serif fonts more readable in smaller font sizes and for longer passages. | + | Now, you may have noticed in the screenshot above that, despite my reference to the heading font being bold sans serif, the menu at the top of Writer shows non-bolded Caslon 540 in 12-point size.

- | The next thing we’ve done for this month’s column is, of course, to put in the screenshot above showing the Writer window and the Launcher. There are two ways that I capture screenshots for the column: Use the ‘Prt Sc’ key on your keyboard to capture the entire screen, as done above in order to include the Launcher. More often in these columns, I want to capture only the active window, which can be accomplished by using the key combination of ‘Alt’ (hold the key down), then ‘Prt Sc’. Either way will invoke Linux’s screen capture utility (below). | + | Lancez-le en cliquant sur l' |

As you can see above, the default format is PNG. This will not work for a final screenshot, as Big Chief Ronnie Tucker, publisher non-pareil, needs the screenshots in JPEG format.

The GIMP is an outstanding (and FREE) raster graphics and image editor that has been around since 1996. It is available on Linux, Mac, and Windows, so if you learn how to use it, you can then use it, and its now familiar interface, on other machines, a great thing about many of Linux’s applications. Open the GIMP and navigate to the save location for the screenshot, then open it. In my case, I always have the file manager open to the save location where I just put the screenshot, so I invoke the GIMP by right-clicking the PNG file and select ‘Open with Other Application’, | The GIMP is an outstanding (and FREE) raster graphics and image editor that has been around since 1996.

Now, once you need to insert the screenshot, position the cursor at the desired text location in Writer and select the Insert menu and select Image. Navigate to the image’s location and double-click it to insert it. You can reposition the image by clicking and dragging, and you will probably need to use carriage returns to get your text just where you want it. Now, write a brief bio at the bottom of the document and Presto! You’ve completed a Full Circle magazine column. I use Thunderbird to email it to Ronnie as an attachment (we’ll visit email applications in some detail in a later column). | ||
