GetImageSizeWithinArea
Declaration
function GetImageSizeWithinArea(ImgWidth, ImgHeight : integer;
DestWidth, DestHeight : integer;
bAllowStretching : boolean = TRUE;
FitMethod: TFitMethod = _fmFitWithinRect
): TPoint;
Description
Return the new size of an image we wish to fit within an area of size DestWidth x DestHeight while maintaining the original aspect ratio
| Parameter | Description |
| ImgWidth, ImgHeight | The dimensions of the image |
| DestWidth, DestHeight | The space available for the image (e.g. the client area of a display control, such as a TImageEnView) |
| bAllowStretching | If the image is smaller than the available area it will be stretched to the full available size (otherwise result is the original width/height) |
| FitMethod | Generally _fmFitWithinRect, but _fmFillRect_WithOverlap will return an image that makes the image as large as possible without any border area (so one dimension will match the available size, and the other will generally be larger) |
Example
// We want size for a thumbnail no larger than 100x100, but at same aspect ratio as source image
sz := GetImageSizeWithinArea( SrcBMP.Width, SrcBMP.Height, 100, 100 );
