Is gimp as good as Photoshop?

Well, to be fair, you probably don’t want that either. As far as I know, the current version of the Gimp software doesn’t come with a built-in tool for Gimp’s pixel drawing. Instead, you’ll have to write custom scripts that will open up a window with the source of your images and draw in the pixel format.

This is annoying, because in order to keep your image from getting pixelated, you need to be able to draw accurately in the Gimp format. That means that the Gimp tool has to run the pixel drawing in the correct coordinate system, which means it needs to know where to draw in the world and how to draw in it. Because this is complicated and doesn’t work well in most cases, I wrote a custom utility named PixelMap to handle these issues. The utility lets you draw pixel maps that can be viewed with Gimp’s built-in pixel drawing command.

In the image below, each frame of a still photo is a different color, showing where each color is on the map, then mapped onto each pixel. When you draw a drawing in PixelMap, it can convert the image to an RGB format with the right colors in the right places, leaving the rest at the default R and G color settings, using the tool’s built-in PixelDraw command.

PixelMap isn’t perfect, though. When using it, you can’t use a command-line tool like Gimp’s PixelDraw to draw, because the tool assumes your image represents a point in space, not a drawing that takes in one coordinate system.

That means we have to use a custom pixel image format. Here’s an example of what that might look like:

#include #include // This example will draw the pixel image in two colors so you can see the difference PixelData data = PixelImageData(format, 4, pixelsize); PixelData data2 = PixelImageData(format, 2, pixelsize); float color = RGBConvert.ToRGBA(int(pixelData.r), int(pixelData.g), int(pixelData.b)); // We can use one color for our point and another for our point & line coordinates PixelLineLine data2PixelLine = new PixelLineLine(color, data2);

The above example will draw lines the colors red, green
