The code as follow, you will get the Print PreView Dialog, but if there is a measurement line on the image, the measurement value displayed on the image is different from that in the print preview, the error like attached image.
ImgEnMain->IO->DoPrintPreviewDialog(iedtDialog , Caption, true, "Print PreView", true);

In addition, the same error occurs when you assign an imageenview to another imageenview.The code as follow#65306;
TIEBitmap *tmpIEBmp = new TIEBitmap;
tmpIEBmp->Width = DstImgWidth;
tmpIEBmp->Height = DstImgHeight;
tmpIEBmp->PixelFormat = imgTmpNavi->IEBitmap->PixelFormat;
imgTmpNavi->Assign(ImgEnMain);
imgTmpNavi->LayersMergeAll();
My ImageEn is 10.2, and IDE is 10.4

Hi

This can happen if the TImageEnView has been scaled. Before assigning, ensure you call:


ImageEnView2.ScaleX := ImageEnView1.ScaleX;
ImageEnView2.ScaleY := ImageEnView1.ScaleY;

Before printing you will need to merge or set the text of line layers (i.e. by turning off ruler mode).

We will handle this automatically in the next update. You can email me for a pre-release if you like.

I set scale and rulerparas's unit as follow:
imgTmpNavi->ScaleX = ImgEnMain->ScaleX;
imgTmpNavi->ScaleY = ImgEnMain->ScaleY;
imgTmpNavi->RulerParams->Units = ImgEnMain->RulerParams->Units;
but it only works when scale equals 1.
