Q.3 Do we need an X Server to run in Batch Mode for GIMP?

Yes, you have to have some form of X server to run GIMP in batch Mode. It needs an X server for image processing, and for font manipulation. However, if you wish to run in batch mode, you can run with a special, frame-buffer-less X server called Xvfb, which doesn't require a graphics card or mess with your screen.

Q.4 How do we draw in a different color in GIMP?

To draw a different colour in Gimp you need to go at the bottom of the toolbar where there is a box with two smaller boxes and an arrow. The uppermost box displays the current foreground color; the lowermost box displays the current background color. You can double-click on either of the color boxes ( to pop up a color selection tool, with which you can select any color you like for that box. That color then becomes the new foreground or background color. Subsequent drawing operations now uses these colors for future work

Q.5 Why should we place layer Groups In GIMP?

Sometimes it is nice to place layers in groups. It not only makes them easier to organize when you have lots of them but also means that you can easily apply the same effect to lots of layers, without directly affecting those layers. Moreover, this will be much easier to program once GEGL has been integrated into GIMP.

Q.6 How do we call one Script-fu Script from another?

The trick to calling script-fu-scripts from another script is to just reference the main define for the script and not to try to use the pdb call. All the scripts in script-fu share a common name space; you call other scripts just like a regular function / define / whatever you call those things in_scheme.

Q.15 What is Script-fu In Gimp?

Script-Fu is the first GIMP scripting extension. Extensions are separate processes that communicate with the GIMP in the same way that plug-ins do. The distinction is that extensions don't require an active image to operate on, instead extending GIMP's functionality. GIMP internals for version 1.0 have been completely overhauled from version 0.54. In particular, the plug-in API has been made far more general with the advent of the procedural database (PDB). The PDB allows GIMP and its plug-ins to register procedures which can then be called from anywhere: internally, from extensions, and from plug-ins.

Q.22 What Are Pseudo-elements?

Pseudo-elements are fictional elements that do not exist in HTML. They address the element's sub-part (non-existent in HTML) and not the element itself. In CSS1 there are two pseudo-elements: 'first-line pseudo-element' and 'first-letter pseudo-element'. They can be attached to block-level elements (e.g. paragraphs or headings) to allow typographical styling of their sub-parts.

Q.24 Explain Project Initiation Process in Graphic Design?

One of the most important steps in the design process is accumulating the information you’ll need. This is usually achieved by either a face-to-face meeting with the client, a questionnaire, or even a Skype meeting if you really wish to establish a personal relationship. In gathering this information, you now know your client’s objectives and can focus on the details for inclusion in your brief. It ensures the client knows what he or she wants from the project It acts as your point of reference during the project

Q.34 How do you sharpen a fuzzy image?

The most generally useful technique for sharpening a fuzzy image is called the Unsharp Mask. It is a plug-in, and you can access it as Filters->Enhance->Unsharp Mask in the image menu. There are two parameters, "Radius" and "Amount". The default values often work pretty well, so you should try them first. Increasing either the radius or the amount increases. However, if you make the unsharp mask too strong, it will amplify noise in the image and also give rise to visible artifacts where there are sharp edges the strength of the effect.

Q.43 What are the components of Zoom Submenu?

The Zoom submenu contains various commands which affect the magnification of the image in the image window (zooming). Enlarging an image (zooming in) is useful if you need to work with high precision, making pixel-level image modifications or precise selections. On the other hand, reducing an image (zooming out) is handy for getting an overall impression of the image and seeing the results of changes which affect the entire image.

Q.45 What is the Gamma Dialogue?

The correspondence between electrical intensity and color brightness is not exact and it depends upon the device. "Gamma" is a coefficient used to correct this correspondence. Your image must be visible in both dark and bright areas, even if it is displayed on a monitor with too much luminance or not enough. The "Gamma" Display Filter allows you to get an idea of the appearance of your image under these conditions.

Q.47 What is the purpose of Flatten image Command?

The Flatten Image command merges all of the layers of the image into a single layer with no alpha channel. After the image is flattened, it has the same appearance it had before. The difference is that all of the image contents are in a single layer without transparency. If there are any areas which are transparent through all of the layers of the original image, the background color is visible.
