TImageEnProc.ResampleTo
Declaration
procedure ResampleTo(Target: TIEBitmap; TargetWidth, TargetHeight: Integer; FilterType: TResampleFilter; MaintainAspectRatio: Boolean = False);Description
Copies a resized instance of the current image to a Target TIEBitmap. The content of the destination image changes (i.e. it is stretched to the new size).| Parameter | Description |
|---|---|
| Target | The target (destination) image |
| TargetWidth | Width in pixels of the target size. If TargetWidth is -1 then it is calculated automatically, respecting the proportions |
| TargetHeight | Height in pixels of the target size. If TargetHeight is -1 then it is calculated automatically, respecting the proportions |
| FilterType | Resampling interpolation algorithm |
| MaintainAspectRatio | Automatically reduces NewWidth or NewHeight to ensure the original proportions of the image are maintained |
Supported filters by PixelFormat:
| Filter | ie1g | ie8g | ie16g | ie24RGB | ie32RGB | ie48RGB |
