TIEDBMultiBitmap.Resample
Declaration
procedure Resample(idx: integer; NewWidth, NewHeight: integer; FilterType: TResampleFilter = rfNone; MaintainAspectRatio: Boolean = False; ShrinkOnly: Boolean = False); overload;
procedure Resample(idx: integer; ScaleBy: Double; FilterType: TResampleFilter = rfNone); overload;
Description
Resizes a frame of the current image and updates the database. The content of the image changes (stretched to new size).
Overload 1
| Parameter | Description |
| idx | The frame to resample |
| NewWidth, NewHeight | New dimensions of the image |
| FilterType | The resampling interpolation algorithm used to improve the quality. If you specify an incompatible algorithm for the pixel type an alternative will be automatically selected |
| MaintainAspectRatio | Automatically reduces NewWidth or NewHeight to ensure the original proportions of the image are maintained |
| ShrinkOnly | If true and the new dimensions would enlarge the image, the resampling as skipped |
| Parameter | Description |
| idx | The frame to resample |
| ScaleBy | The amount to scale the image. E.g. 0.5 would halve the size of all images while respecting the proportions |
| FilterType | The resampling interpolation algorithm used to improve the quality. If you specify an incompatible algorithm for the pixel type an alternative will be automatically selected |
Note: If
Mode = dmRecordFrames, this method only resamples a frame of the current image and does NOT update the database. You will need to call
UpdateDatabaseImage
// Halve the size of the first image in a TImageEnMView attached to a TIEDBMultiBitmap
fDBMBitmap.Resample( 0, 0.5, rfLanczos3 );
