Summary
Scales a graphic to a bitmap.
Pascal
procedure Stretch(NewWidth: Cardinal; NewHeight: Cardinal; Filter: TResamplingFilter; Radius: Single; Source: TGraphic; Target: TBitmap); overload;
procedure Stretch(NewWidth: Cardinal; NewHeight: Cardinal; Filter: TResamplingFilter; Radius: Single; Bitmap: TBitmap); overload;
Parameters
| Parameters | Description |
| NewWidth: Cardinal | The new width of the target bitmap. |
| NewHeight: Cardinal | The new height of the target bitmap. |
| Filter: TResamplingFilter | The filter to be used. |
| Radius: Single | The radius in pixels that will influence the current pixel. This can be a fractional to use partial pixels. |
| Source: TGraphic | The source graphic. |
| Target: TBitmap | The target bitmap. |
| Bitmap: TBitmap | The bitmap to scale. |
Description
Scales the source graphic to the given size (NewWidth, NewHeight) and stores the Result in Target. Filter describes the filter function to be applied and Radius the size of the filter area. If Radius = 0 then the recommended filter area will be used (see DefaultFilterRadius). With the filters you can determine the quality and the speed of the conversion, use a Box or Triangle filter for fast previews and a Lanczos3 or Bell filter for better quality.
