Outputs multiple images (all or just selected) in the attached TImageEnMView or TIEMultiBitmap as rows and columns of thumbnails to a file.
Result is the number of pages (bitmaps) required to output all thumbnails.

Parameter Description
Dest The destination bitmap for these thumbnails. If iPageNo is not set, then only the first page will be output. Dest can be nil to return the count of pages.
iImageWidth The output width for the image (in pixels)
iImageHeight The output height for the image (in pixels)
iColumns Specifies how many thumbnails span across the page
iRows Specifies how many thumbnails span down the page
iHorzSpace The horizontal space between thumbnails (in pixels)
iVertSpace The vertical space between thumbnails (in pixels)
bPrintSelectedOnly Set to true to print only selected images. False to print all image in the TImageEnMView
iHorzMargin Page margin on left and right of the image (in pixels)
iVertMargin Page margin on top and bottom of the image (in pixels)
CellBorder Set to true to draw a box around the each image cell (space containing the area of the image and its text).
ShowText Set to true to draw text associated with every image. Note: The font of the text will be used, e.g. BottomTextFont
DropShadow Set to true to draw a shadow around the image.
BorderColor Specifies the color of the box around the image or cell (i.e. when CellBorder or ImageBorder is True).
Heading Specifies the heading to print at the top of the page. If you append ### (e.g. 'Thumbnails###') it will append "Page x" to printed pages after the first one.
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.
iPageNo The page of thumbnails to output.
ImageBorder Set to true to draw a box around each thumbnail (edge of image).

- The images will maintain their aspect ratio when stretched
- Use the OnPrintPage or OnPrintPage event to customize the heading


// Save image of thumbnails
ImageEnMView1.MIO.PrintImagesToBitmap(MyBitmap, Screen.Width, Screen.Height, 6, 4, ...);

// Get number of bitmaps needed to output all thumbnails
pageCount := ImageEnMView1.MIO.PrintImagesToBitmap(nil, Screen.Width, Screen.Height, 6, 4, ...);
