Raster image

Raster or bitmap image refers to an image stored by a computer in a specific way.

Raster images are composed of pixels. Each pixel has an assigned color (and eventually another parameter, for example transparency). Pixels are arranged in rectangular net of given width and height.

Raster image consists of pixels
Raster image - squares (pixels) are visible in the zoomed-in area.

Raster images can be modified by changing colors of individual pixels. Pixels can be changed one by one or in groups by drawing tools. For example the line tool can create an effect of a drawn line by changing colors of pixels laying along the defined line.

Due to the nature of raster images, once the the line tool changes the pixels (user applies the operation), the information about them forming a line is lost. Therefore, it is impossible to change a line after it was drawn.

The fundamental property of a raster image is its size - the width and height in pixels. When creating raster images, you can specify their size.

C'est très bien le concept de crée une aplication pour crée des cursor mais n'hésiter pas à agrandir les pages des créations ! Merci de votre compréhension.
