Note-1: We need not use oImage for printing. We can straight away use the image source, viz, filename, resource or any source of image.
Note-2: TImage requires 'freeimage.dll'. Better to use TBitmap or TXImage instead so that our application runs without freeimage.dll.

This is a simple sample to print images.

Sorry my error

How make Image with Box ?

[nageswaragunupudi]

If you need to use CM, you just use "CM" instead of "INCHES" in the above command.
There is no need to create new functions for this.

ok How I can make to insert an image on a box


sample I use for a text

Code: Select all  Expand view

IF lBorder
         oPrn:Box(X, Y, Z, K,;
                { nColorBordo, SetBorder(nSizeBordo) }, nBackcolor, ;
                {cText,  oFnt, nColorFont, SetAlign(nAlignOriz,nAlignVert) }, ;
                 "CM" )
      else
          oPrn:Box(X, Y, Z, K,;
                { CLR_WHITE, 1 }, CLR_WHITE, ;
                {cText,  oFnt, nColorFont, SetAlign(nAlignOriz,nAlignVert) }, ;
                 "CM" )
        endif
