M msains Member Licensed User Longtime User Oct 18, 2019 #1 Calling BitMapCreator Experts. I have a GrayScale Bitmap (see picture) of dimensions 199 x 262. I would like to (programmatically) put a border around it and save it (again) as a .bmp The border I put around it must cause the final combined bmp to ... a) have dimensions of Exactly 512 x 512 b) The border must be filled with pixels that copy the original bmp's pixel(0, 0) I guess another way of saying this is that I would like to place the original bmp more or less in the centre of a new 512 x 512 bmp whose background is made up of pixels like the original's Pixel(0, 0) For (arithmetical) simplicity let's say the borders dimensions would be (in pixels) Top & Bottom Borders = 512 x 125, Left Border = 157 x 512, Right Border = 156 x 512 I'm really impressed by the BitMapCreator lib but just can't get into it that easily. A bit of practical help (like the above) might help to get started into it more quickly. Is this something that BitMapCreator can do (like - in its sleep) with only a few lines of code ?

Depending on what you then do with the bordered image, another way might be: - create a Panel that is 512 x 512 pixels - add an ImageView to the panel, so that its position coordinates are relative to the panel - load the .bmp to the ImageView - set the Panel to be solid color of the (0, 0) pixel of the ImageView - center horizontally with ImageView.Left = (Panel.Width - ImageView.Width) / 2 - center vertically likewise You can then move the Panel around the screen as required. Some panels have a SnapShot method that will return the image with the border. Upvote 0

No worries I know my post didn't meet your opening criteria, but I figured I'd pop out a different way of doing it anyway because: 1/ always good to have a backup plan 2/ usually good to see things from alternative perspective Upvote 0

I was experimenting in BMC with 'brushes' and not really getting anywhere. This is much simpler and I can work up to using 'brushes' later. I also appreciate all the comments in your code. You must be a teacher or lecturer because the explanations are brief but very instructive. Thanks again. Upvote 0

No - I wish I had known there was a booklet. Probably my fault for not finding it - but It would possibly have given me the solid start on BMC that I needed. Once again the value of this great community is shown. Thanks again. Upvote 0
