== GIMP ==
GIMP is a powerful and complex open source image
editing programme. The GIMPs tools are displayed as icons on the
toolbox. A
user can identify a tool by hovering over it. The name of the tool
will appear below. Clicking on the icon will select that
corresponding tool.
A beginner can utilise the following tools in GIMP:
=== Crop ===
Select the area that you would like to retain. The area can be
extended or reduced by selecting one of the sides. Once your desired
area is selected (the remaining area will turn grey or darker), then
double click inside the desired area. The photo will be cropped to
that size.
The tool is used:
* to reduce the size of large images.
* to remove unnecessary areas in a photo.
=== Scale ===
Open the image that you want to work on in GIMP. Select the scale
tool and click on the image. The image would then have tiny boxes on
every side. Another box will pop up. You can insert the measurements
that you want in this box. Or you could manually drag with the help
of clicking one of the sides and reduce to the size you want.
The tool is used:
* to reduce the size of heavy images. It makes uploading on websites more easy.
=== Move ===
After scaling an image, if you want to add another image to the
frame, you would have to move the first image to the side. This can
be done using the move tool. Select the move tool. Select the image.
Click and drag to a suitable location.
The tool is used:
* when there is more than one element in the window you are working on.
=== Add text ===
Select the Text tool (a capital A). Now, drag the tool to were you
want to insert text. A tiny box pops up. Type your text in the box.
The size, colour, style of the text can be changed in the settings
below the tool box. The length of the text box can be adjusted after
you finishing typing your text by selecting the corners and dragging.
The tool is used:
* to add a title or caption explaining the text is useful.
=== Grayscale ===
Select the image. Go to the menu bar on top and click on the
'Image' option. Then click on 'Mode' and finally click on
'Grayscale'. This would make the image grey.
The tool is used:
* to make a photo black and white. It is preferrable for printing purposes.
=== Scale image size ===
Select the image. Go to the menu bar on top and click on the
'Image' option. Then click on 'Scale image...'. This would show you
options of 'width and height' along with 'X resolution' and 'Y
resolution'. Enter in 72 pixels in both X and Y spaces. This would
help reduce the file to a small size.
The tool is used:
* to reduce resolution which helps in file size.
* to make photos for uploading on websites (should not be used for printing).
<br>
=== Transparent background ===
Open the image you want to work on. Once the image is open, go to
File → Save as → and save it as a .png file. Once this is done,
go to Layer → Transparency → and see if the option 'Color to
Alpha' is active. If yes, then click on it and say yes. This will
make your background transparent. If no, this tool cannot be applied
to this image.
This tool is used:
* to make white backgrounds transparent.
* to remove backgrounds from logos.
=== Sepia photos ===
Import the image into GIMP. There is more than one way to do this.
'''One: '''Go to Color →
Colorize. A dialogue box will pop up. Adjust the bars to your desired
levels. Else let the values be around Hue: between red and yellow –
25 to 35. Saturation: Between 50 – 60. Lightness: Between 4 –
10.
'''Two: '''Go to Filters →
Decor → Old photo.
'''Three: '''Another method
requires you to first desaturate the image. For this, go to Color →
Desaturate. Then repeat the processes in method '''One'''.
<br>
<br>
=== Layers ===
The
importance of working on layers in a canvas is to meddle with more
than one photo. In case your layers box is not visible, go to Windows
→ Recently closed docks → Layers, Channels, Filters. You can
slide the layers one above the other. But the user must keep in mind
that actions such as desaturate/ sepia will be done on the '''active
layer'''. The action will have to be repeated on every other layer.
