Description
Loads an image of any format into a TIEBitmap reducing it to the specified size (while maintaining the aspect ratio, thus one of the dimensions is likely to be less than the specified value).| Parameter | Description |
|---|---|
| MaxX, MaxY | The maximum size of the new image (as the aspect ratio is maintained, one of the dimensions is likely to be less than the specified value) |
| StretchSmall | Set to false to avoid images smaller than MaxX x MaxY from being made larger |
| AutoAdjustOrientation | Sets EnableAdjustOrientation to automatically re-orient JPEG camera images |
| QualityFilter | Specify the quality that is used for rescaling the image |
| bAddBorder | Set to true to add a 1 pixel border to the thumbnail |
| cBorderColor | The color of the added border |
| bAddShadow | Add a solid or soft shadow to the image |
| iBlurRadius | Set to 0 to add a solid shadow or any other value for the width of the Soft Shadow |
| iShadowOffset | The offset of the shadow from the image |
