I'm trying to let the user import an image in my windows application, in any pixelformat, but i need to save the image in 16bpp4444 format, and that is not an option for pixelformat in .Net imaging class.

I have an image that is using an indexed pixel format. I can't load such an image into a graphics object using loadimage. Ultimately, all I am trying to do is to overlay one bitmap onto a different one, neither of which will be visible for some time, if ever. That looks like it can be done fairly easily by loading the BMP into a graphics object, then drawing the other image onto it. However, that would require transforming the incoming image from an indexed pixel format to a non-indexed format.

I need to convert these forms into images that I can paste into the report.
Is this possible? I dont want to include a folder of all the images.I want to be able to take an image from the resource and export it to a file.
View 3 RepliesI'm developing a standalone application. The purpose of it is to have no installation necessary. I'm trying to keep it as small as possible, and everything contained in the actual program, so that the user can let it sit right on their desktop. I wanted to make it possible to generate an image, preferably something transparent (.png, .gif) of a certain dimension, and export it to a certain folder. I've explored Bitmap library, but I've yet to come up with a successful solution. I'd be very obliged if someone could point me in the correct direction. Here's my current code:
Dim myPNG = New System.Drawing.Bitmap(fileName:="logo.png")
myPNG.SetResolution(xDpi:=100, yDpi:=20)
myPNG.MakeTransparent() 'creates transparency
myPNG.Save("C:logo.png")

I'm developing an application in VB.Net (VS2008) which allows the creation of classroom layouts. The layout is a panel and has child panels (seat objects) the seats are then populated using drag and drop and show a preview of the person sitting there.
I would like to export this panel to a printable format such as jpeg, pdf etc.I have tried using the CopyFromScreen but I can't get this to only output the layout panel. (some of the panel could be off the screen at the time of export)I have also considered using HTML outputting each seat as an absolutely positioned div container. Then printing the HTML page.
if this is the case.What I'm trying to do:1) have a way to save / copy screenshot from an Air app2) automatically paste such screenshot into a new powerpoint slide in the current presentation

I've been searching for hours tonight searching existing posts, other websites and all i can find are examples of how to capture a image from a webcam.Does anyone have any code that simple talks to the camera device via WIA, and then saves every image found on the device to a hard drive?I found this code below. Credit i cant tell you as i have a bunch of different flavors of code, but this only saves the file as a tmp file, and not the actual image file i expected after selecting?

Am having an image in my Project-solution and i need to set the image dynamically?for a picture box of winforms in vb.net?
View 1 RepliesI have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this:
Dim bte() As Byte = System.Convert.FromBase64String(imgStr)
Dim ms As New IO.MemoryStream(bte)
Dim bmp As New System.Drawing.Bitmap(ms)

And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line.

My Problem is that I am trying to view the database in Vb (windows form) but the image does not appear.All I can see is a small red cross where the image should be.I have tried both Datagrid view and Detail View.
View 3 RepliesI'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click

I'm considering a personal learning project. Using .NET(preferably VB) I want to build a simple desktop app that's only function is to display comics, like CDisplay, but with more advanced navigation. I want to be able zoom in by clicking on certain areas of an image, individual panels for instance, and have the zoom area automatically snap to the panel and blow it up. The images are usually in a standard format like .jpeg, .png, etc..
Something like this is what I'm going for: [URL]
I'm not even sure what this is called? Image mapping? Tone mapping maybe? Is it possible to do this within .NET or would it require some kind of outside library? Code samples would be nice, but obviously this is pretty vague request.
