image.copy is a function that is part of image.
The function returns a copy of the input image scaled to fit the specified pixel width and height.
The width and height default to the size of the input image.
The routine raises an error if the new width or height are less than or equal to 0 or greater than 25000.
The routine raises an error if there is insufficient memory to create the new image.
This has been introduced in TI-Nspire OS 3.0 (Changes).
Syntax
image.copy(image, width, height)
| Parameter | Type | Description |
|---|---|---|
| TI.Image | The original image. | |
| number | The width of the new image | |
| number | The height of the new image |
Example
newImage = image.copy(oldImage, 10, 15)Good to know
To make a relative scale, use
image.copy(image, scaleX * image.width(image), scaleY * image.height(image))See also
