Description

Print the specified image by specifying margins, vertical position, horizonal position and size.

Parameter	Description
ImageIndex	Index of the page/image to print (0 = first image). IEM_SELECTED_IMAGES can be specified for ImageIndex to print all images that the user has selected in the TImageEnMView or IEM_ALL_IMAGES to print all images in the TImageEnMView
PrtCanvas	The printing canvas. Specify nil to use the Printer.Canvas
MarginLeft	Left page margin in inches (Specify zero for no margin)
MarginTop	Top page margin in inches (Specify zero for no margin)
MarginRight	Right page margin in inches (Specify zero for no margin)
MarginBottom	Bottom page margin in inches (Specify zero for no margin)
VerticalPos	Vertical alignment of the image on the page, e.g. ievpCenter to center
HorizontalPos	Horizontal alignment of the image on the page, e.g. iehpCenter to center
Size	How the image should be sized for printing
SpecWidth	The absolute width of the image in inches if Size = iesSpecifiedSize. The number of pages wide if Size = iesMultiplePages
SpecHeight	The absolute height of the image in inches if Size = iesSpecifiedSize. The number of pages high if Size = iesMultiplePages
GammaCorrection	Level of gamma correction, use 1 to disable gamma correction
PrintAnnotations	If true and the image contains imaging or ImageEn annotations they will be printed
Heading	Specifies the heading to print at the top of the page
HeadingHeight	The height of the heading, as a PERCENTAGE of the overall page height, e.g. 5 will make the heading 5% of the page height
HeadingColor	Specifies the color of the heading text

Note:
◼You do not need to call Printer.BeginDoc/Printer.EndDoc unless you want to print a batch of images
◼Use the OnPrintPage or OnPrintPage events to customize the heading added to each printed page
◼When using iesSpecifiedSize, SpecWidth or SpecHeight will be adjusted to maintain the image's aspect ratio. Set PrintingMaintainAR to false to prevent this
◼If you are printing a PDF, you should use Print

Example

// Print the first image in center of the page with original sizes
ImageEnMView1.MIO.PrintImage(0, 0, evpCenter, iehpCenter, iesNormal, 0, 0, 1);

// Print the selected image(s) stretched to the page center (respecting the proportions)
ImageEnMView1.MIO.PrintImage(IEM_SELECTED_IMAGES, 0, ievpCenter, iehpCenter, iesFitToPage, 0, 0, 1);

// Print all images stretched to the page center (respecting the proportions)
ImageEnMView1.MIO.PrintImage(IEM_ALL_IMAGES, 0, ievpCenter, iehpCenter, iesFitToPage, 0, 0, 1);

// Print the first five images as posters, four pages wide and six pages high
Printer.Title := 'ImageEn';
Printer.BeginDoc();
for i := 0 to 4 do
ImageEnMView1.MIO.PrintImage( i, 0, ievpCenter, iehpCenter, iesMultiplePages, 4, 6, 1);
Printer.EndDoc();
