Example

// =============================================

// This sample scale image size matching 200 DPI

// =============================================

// Get current resolution

XRes:=ImgGetHorzResolution(_CurrentImage);

YRes:=ImgGetVertResolution(_CurrentImage);

// Get current size

XSize:=ImgGetWidth(_CurrentImage);

YSize:=ImgGetHeight(_CurrentImage);

// Calculate new size at 200 DPI

NewXSize:=Round((XSize/XRes)*200);

NewYSize:=Round((YSize/YRes)*200);

// Scale the image to a new size

ImgScale(_CurrentImage, NewXSize, NewYSize, True);

// Set image to 200 DPI resolution

ImgSetHorzResolution(_CurrentImage, 200);

ImgSetVertResolution(_CurrentImage, 200);
