Show a basic storage type to handle a simple RGB raster graphics image,
|
|
and some primitive associated functions.
|
|
|
|
If possible provide a function to allocate an uninitialised image,
|
|
given its width and height, and provide 3 additional functions:
|
|
* one to fill an image with a plain RGB color,
|
|
* one to set a given pixel with a color,
|
|
* one to get the color of a pixel.
|
|
|
|
(If there are specificities about the storage or the allocation, explain those.)
|
|
|
|
''These functions are used as a base for the articles in the category [[Raster_graphics_operations|raster graphics operations]],
|
|
and a basic output function to check the results
|
|
is available in the article [[write ppm file]].''
