So, I was wondering what it is for? why even say get image if all you are doing is paste an image? Not shure what this command is for.

my signature keeps being erased by a mod So this is my new signature.

After composing an image on a bitmap, you use GET image to...get the image.

example - create numbered balls - paste the ball image, write the text, get the image. 1 image file could create 100 numbered ball images.

It's also very useful for making bitmap fonts from a font sheet.

Explaining it deeper - a sample

+ Code Snippet

For Y=0 to 20
    For X=0 to 20
        If drawdot = 1 Then dot X,Y
        If drawdot = 0
            drawdot = 1
        else
            drawdot = 0
        endif
    next X
next Y

Get image 1,0,0,20,20 `Get image from x=0, y=0 to x2=20, y2=20
CLS `Clear the screen

number = 1

For Y=0 to 5
    For X=0 to 5
        Sprite number,X*20,Y*20,1
        inc number
    next X
next Y

Just paste the code and see how it works

For the simple reason you might want to get it from one place and paste it somewhere else.

Most of our code examples use GET IMAGE because it's easier to run code that doesn't require any media for examples. Without GET IMAGE we'd be attaching media 100% of the time just to help people with 2D problems.

Just as BatVink mentioned it's mainly to give us the ability to manipulate images and grab the results to use in our programs.

This shows what Green Gandalf mentioned and to show you two ways to use GET IMAGE (to blur or not to blur).

+ Code Snippet

` Make a box outline
line 0,0,50,0
line 0,0,0,50
line 50,0,50,50
line 0,50,51,50
line 25,0,25,50
line 0,25,50,25

` Grab the box blurred (texture flag 0)
get image 1,0,0,51,51

` Grab the box pixel perfect (texture flag 1)
get image 2,0,0,51,51,1

` Show blurred image (image 1)
paste image 1,100,100,1

` Show pixel perfect image (image 2)
paste image 2,100,200,1

` Identify each image
text 55,18,"<-( Original Image )"
text 155,118,"<-( Blurred Image - Texture Flag 0 )"
text 155,218,"<-( Pixel Perfect Image - Texture Flag 1 )"
