The RasterImageList control (and RasterThumbnailBrowser that inherits it) allows the customer to do custom drawing of the items if you set the RasterImageList.ViewStyle property to RasterImageListViewStyle.OwnerDraw.  However, it can be difficult to draw the correct size when an image has a skewed DPI (e.g. 200x100).  Our tools have already done all the math for you and will return the correct sizes.  Attached is a C# 2005 project that uses LEADTOOLS 16.5 to accomplish this goal.  The main functions and properties used are:

- RasterImageList.ViewStyle
- RasterImageList.UseDpi
- RasterImagelist.DrawItem event
- RasterImage.GetImageWidthDpi

- RasterImage.GetImageHeightDpi
File Attachment(s):
NET - v16 - RIL UseDpi.zip (61kb) downloaded 19 time(s).
