zoom_image

Herror ::zoom_image_size ( Hobject Image, Hobject *ImageZoom, const HTuple &Width, const HTuple &Height, const HTuple &Interpolation ) HImage HImage::ZoomImageSize ( const HTuple &Width, const HTuple &Height, const HTuple &Interpolation ) const HImageArray HImageArray::ZoomImageSize ( const HTuple &Width, const HTuple &Height, const HTuple &Interpolation ) const

Zoom an image to a given size.

::zoom_image_size scales the image Image to the size given by Width and Height. The parameter Interpolation determines the type of interpolation used (see ::affine_trans_image).

Parameters

`Image` (input_object)	(multichannel-)image(-array) `->` Hobject: HImage(Array) ( byte / int2 )
Input image.

`ImageZoom` (output_object)	(multichannel-)image(-array) `->` Hobject : HImage(Array)* ( byte / int2 )
Scaled image.

`Width` (input_control)	extent.x `->` HTuple.long
Width of the resulting image.
Default value: 512
Suggested values: 128, 256, 512
Typical range of values: `2 <= Width <= 512`
Minimum increment: 1
Recommended increment: 10

`Height` (input_control)	extent.y `->` HTuple.long
Height of the resulting image.
Default value: 512
Suggested values: 128, 256, 512
Typical range of values: `2 <= Height <= 512`
Minimum increment: 1
Recommended increment: 10

`Interpolation` (input_control)	string `->` HTuple.char *
Type of interpolation.
Default value: 'constant'
List of values: 'none', 'constant', 'weighted'

Example

read_image(&Image,"affe");
disp_image(Image,WindowHandle);
zoom_image_size(Image,&ZooImage,0,200,200);
disp_image(ZooImage,WindowHandle);
