PNGResample (resize a PNG)

function PNGResample(
  imgFile:   string,
  maxWidth:  number,
  maxHeight: number
): boolean;

Resizes the specified PNG image (imgFile) using the Lanczos3 resampling method for optimal detail.

• Maintains the original aspect ratio.
• Chooses the smaller of maxWidth or maxHeight (in pixels) as the limiting dimension. Set either to 0 to ignore that constraint.

Returns true if the image was resized successfully, or false if an error occurred.

Example

PNGResample('./self_portrait.png', 800, 600);
