Description of the component
The ShapeDiverImageSampler component works similarly to the standard grasshopper ImageSampler, except the local input file is replaced by a Grasshopper Bitmap.

Applications
The Image Sampler allows Grasshopper to analyze images and use them to influence geometrical algorithms for example. Using Squid along the Image Sampler, one can also re-process input images and export them from Grasshopper and the ShapeDiver viewer.
Component reference
- Component name: ShapeDiverImageSampler
- Default Nickname: SDImageSampler
- Inputs:
| Name | ID | Description | Type |
|---|---|---|---|
| Bitmap | B | Image a Grasshopper Bitmap to sample. | Grasshopper Bitmap |
| Coordinates | C | Pixel coordinates and X (width) and Y (height) directions. | Point |
| Domain | D | Domain used to sample the image (see details below). | Domain² |
If the domain is left unspecified, it defaults to [1, pixel width] x [1, pixel height]. It can be changed to any other 2D domain, typically [0,1]x[0,1] for unitized pixel coordinates. The Coordinates parameter needs to be given according the specified Domain.
- Outputs:
| Name | ID | Description | Type |
|---|---|---|---|
| Color | C | Pixel color at the (X,Y) location. | Color |
