Hello,

If you are using LEADTOOLS v14 with OCX programming interface, and you want to browse the images and load them to Thumbnail Browser Control, you may try to use the BrowseDir method, which Browses the specified directory for supported images, and generates thumbnails for each image file that is found. For more information, please refer to the LEADTOOLS OCX documentation.
Also, please refer to the following forum:

Hello,

You can save the any image from the LEADImgList as follows:
+------------------------+
Dim Raster1 As New LEADRaster
Dim RasterIO As New LEADRasterIO

Raster1.Bitmap = LEADImgList1.Item(nIndex).Bitma
RasterIO.Save Raster1, "C:\TEST1.BMP", FILE_BMP, 24, 0, SAVE_OVERWRITE
+------------------------+

Thanks,

You can not rotate the image inside the
ImageList control directly. However, you can copy it into a LEADRaster object, rotate
it there using the LEADRasterProcess.Rotate method, then copy it back to the image list.

I've attached a very simple VB 6 project that does this.  It runs on a couple of pre-conditions though:

1. Your image list's selection mode is only single selection
2. The selected item in your image list is what's displayed in your raster view

How can I clear the Image in the LEADRasterView1 after I scan so that I can scan again a new image and I can load a single image into the ImageList?, because in my project if the LEADRasterView has an image and then I scan the image, the scan image will not append in the LEADRasterview because it is not clear, and then it will load the image in the ImageList but same image in the LEADRasterView and double the image... is there any resolution here? thanks... thank you for your reply...

If you want to free the bitmap of the LEADRasterView1.Raster object, set the LEADRasterView1.Raster.Bitmap to 0

I got it... thank you very much for your reply... I have another question about the Imagelist, when I'm rotating the LEADRasterView1 and LEADImgList the rotation is very slow, because after the rotation I'll save it in 1bit so that if I close the pogram it will remain the last positon, why is the rotation is very slow? is that about the saving?  can you give me a sample code... thanks...

I'm not sure I understand the description of the problem. Can
you try to isolate this issue in a small project and send it to me in a ZIP file so I can check it for you?

This issue is not related to the saving process. The slow rotation is related to image size. Rotating the clean.tif image is much faster than sample.tif because sample.tif is larger.
