# Width
|
|
|
|
The width function.
|
|
|
|
Get the width of an [Image](/reference/images/image) in columns.
|
|
|
|
```sig
|
|
images.createImage().width();
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* none
|
|
|
|
### Returns
|
|
|
|
* [Number](/reference/types/number) - the number of columns in a image. This function returns 5 if the image has 1 frame, 10 for 2 frames, 15 for 3 frames and so on. Divide the number of columns by 5 to find out how many frames an image has (see example below).
|
|
|
|
The following example gets the width of `img` and stores it in the `w` variable:
|
|
|
|
### ~hide
|
|
|
|
```
|
|
let img = images.createImage(`
|
|
. . # . . . . . . .
|
|
. # . # . . . # . .
|
|
. . # . . . . . . .
|
|
. # . # . . . # . .
|
|
. . # . . . . . . .
|
|
`)
|
|
```
|
|
|
|
### ~
|
|
|
|
```
|
|
let w = img.width()
|
|
```
|
|
|
|
### Example: show each frame
|
|
|
|
The following example uses the `width` function with a [for](/reference/loops/for) loop to show each image frame on the screen:
|
|
|
|
```
|
|
let img2 = images.createImage(`
|
|
. . # . . . # # # # . # # # .
|
|
. # # . . . . . . # . . . # .
|
|
. . # . . . . . # . . . # . .
|
|
. . # . . . . # . . . . . # .
|
|
. . # . . . # # # # . # # # .
|
|
`)
|
|
for (let i = 0; i < img2.width() / 5; i++) {
|
|
img2.showImage(i * 5)
|
|
basic.pause(1000)
|
|
}
|
|
```
|
