View 2 RepliesI would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how

'The first step is to recognize that the video captured by the web cam can be saved as individual images. By displaying a series of continuous images on the client, it is similar to watching a video stream. To capture an image, I have defined the following subroutine:

The problem is the code fail to retrieve the image from clipboard? What I'm trying to do is connect to a webcam, then save the video stream file on this webcam as bitmap file before transfer to the client side as an array of bytes.

What resources I need to look for, to generate one png image out of three? Since there are sprite generators out there, that do not do what I want, I wanted to try by myself. The user interface should not be the problem, but i have no experience of generating bitmaps, especially those with transparent backgrounds. I will do that in .net. Letīs say I have 6 png files. I want to put them into one image, where there will be two rows of images in it, so 3 in row, 2 in height, 3*2. Every image might have a little different sizes, so i would need to fill up the space with, um, nothing..

I've created a bitmap on which I use setpixel to color it in. Then I display it on a picturebox. I want to clear the bitmap form time to time, reset all its pixels. I see no bitmap.clear() method and there's nothing in the documentation that seems. Short of disposing of or setting the bitmap = nothing and creating a new one, how do I wipe a bitmap?

I'm working on a viewer that shows an image, asks the user for a window and saves the cropped image. Here is an overview of what I'm trying to achieve: The process starts with a 30+MB pdf file containing hundreds of large technical drawings. I open the file with the pdf reader, save as png 300dpi images, then I run my application that works on the saved images. I am interested on a few details of those drawings, and I have two goals:
1) Use my viewer with a subset of details instead of the pdf reader with the full set of whole images, and
2) Pick some cropped details and insert them into another application.
I start the application, look at the first image, click delete, and keep clicking delete until I find an drawing with a detail that I need. Then I draw a rectangle, save the cropped image, and repeat with 3-4 more details on the same image. Then delete the original image, go to the next, and restart the cycle. So I start with 100 large images in my folder and end with 20 small ones. At this point I can browse them very quickly and continue with the following steps (inserting them in another application).
i want open image (png), re size and save it as png-8 with transparent i can re size and save it but this not as png-8 format !!i use this but receive this exeption

I was wondering if it is possible to get a bitmap from a gfx... I am painting straight to a panel in the paint method I DO NOT want to have to paint to a bitmap then return that bitmap then paint this bitmap on the panel - as this is a lot slower I am doing this as i need to obtain a bitmap sometimes (if the user has requested it) 1/2 way through a draw eg the user says i want the picture after it has drawn the 3rd curve (just explaining why I want to do it this way)
