Making an A4 poster using the Gimp

Lesson 1


First off, we begin by creating a new file by placing the mouse over the toolbar and pressing Ctrl + N (or go via File -> New). The new image dialogue box will appear, indicating the size of the image (in this case 1.31MB) and the width and height. We want to make an A4 poster, so we'll chose a rough estimate of 8 x 11 inches with a white background (let's keep our ink usuage to a minimum!).


To begin with, it's important to decide what we're advertising. In this case, it's a street party and it would be nice to have a central photo of last year's event with some inspiring words around it to rally volunteers for this year. First then, we want to create some new layers so we can operate on the parts of the image as we want without affecting other parts. Right mouse click (RMC) over the image and select Layers -> Layers, Channels & Paths. This should bring up your layers dialogue box showing a single, highlighted layer called 'Background'. We need to create a new layer for our imported image. With the cursor over the highlighted layer, RMC and select New Layer. This time we'll accept the defaults (transparent fill type, and whatever size we're given!). A new layer is created, called appropriately 'New Layer'. This should be highlighted, and should show a chequered background to indicate the layer is transparent. We now need to open our picture of last year's street party, so that we can copy it and paste it onto our new layer.


The photo I've chosen, is a normal 6 x 4 colour photo scanned in at only 50 dpi and saved as a jpeg file. Having opened the photo, select using the mouse the part you want (drag the pointer from top left to bottom right to select a rectangle), and then press Ctrl + C to copy the selection. Now change focus by clicking on your poster, and press Ctrl + V to paste your selection. By default, the gimp pastes into the centre of a new image or layer. Your poster and the layers dialogue box should look like the screen shot left.


Next, we'll move the image slightly upwards, so that it appears just underneath the title. Over the photo, press the letter 'm' and then click and drag the photo to the position you want. We can continue to move the pasted in image becuase it remains a floating selection. When we're happy with its position, we can anchor it by double clicking on the selection. The layers dialogue box should change as shown, with the new layer showing the pasted image


Now move on to the next lesson...
