GIMP primary features

Image
GIMP’s primary featuresWhen working on personal projects, there’s one thing which use to always make me waste lot of time - art. Art in the sense of making logo, icon and other images like feature graphics or promotional images. Making something that looks “ok” is not as easy as it seems especially for people like me who have no sense of art whatsoever.Few weeks ago I completed Baskee and had to develop a feature graphic for it. Also my friend came up with the logo idea and I wanted to enhance it to make it more appealing.This sort of skills are always needed as it is hard to find people to do some art things for free. So might as well learn how to do it yourself by using the best free image editor - GIMP.https://www.gimp.org/GIMP has been there for a decade and it is a well established software so I decided to jump into it to enhance Baskee logo and create the feature graphic.Here’s the evolution of Baskee logo from top to bottom (v1/v2/v3):This post is a highlight of some features f…

Absolute layout and relative layout Xamarin forms

Absolute layout and relative layout Xamarin formsIn Xamarin Forms, layouts are used to position elements in the page. There are multiple layouts available like stack layout, grid layout, table layout, absolute layout and relative layout. Stack layout is straight to grasp the concept, we stack elements one by one horizontally or vertically. Grid layout is also straight forward, we define rows and columns and we place the elements by indicating the row index and column index. On the other hand, absolute layout and relative layout isn’t that straight forward because in Xamarin it is NOT the same as positions in CSS.So today, we will see how and when we can use absolute layout and/or relative layout in our advantage. This post is composed by two parts: 1. Absolute layout 2. Relative layout 1. Absolute layoutThe first thing to understand is that absolute layout has nothing to do with CSS absolute position. In Xamarin Forms. absolute layout allows us to position elements in the page by pre…
