I need to save Bitmap object loaded from image file (.png, .jpeg, .bmp) and save it as an icon (.ico) to a separate file.
First I tried saving Bitmap object to a file with Icon ImageFormat:
using System.Drawing;
Bitmap bmp = (Bitmap)pictureBox1.Image;
bmp.Save(@"C:icon.ico", Imaging.ImageFormat.Icon);
This one fails, as the icon produced is not in a proper format and it cannot be used as an icon.
Next one was to get HIcon from Bitmap and save it to a file:
using System.Drawing;
using System.IO;
StreamWriter iconWriter = new StreamWriter(@"C:icon.ico");
[Code]....
This one does not do the job too. Although icon file is properly written, it has only 16 colors and a limited width and height.
I'd like to be able to write icons with custom width and height that would preserve colors from the original image. Is this possible to achive in .NET?
I'm trying to make a solid colored icon in Visual Basic.Right now I make a Bitmap, convert it to a Graphic in order to add color, convert it back to Bitmap, and then try to convert it to an icon.Unfortunately I cannot find any way to convert the final Bitmap to an icon. Can anyone help me with this? Alternatively does anyone have a different way to generate a solid colored icon? [code]
I am searching for some code to help me take the bitmap contents of picturebox1 and convert it into an icon (*.ico) to save. I cannot for the life of me find anything to accomplish this. There are all sorts of codes that do things like convert bitmap files to icon files but nothing to change the contents of a picturebox as an icon.
how can i create an icon (with transparency) from a bitmap?
i've tried this code, which i converted from a create cursor function which worked ok with transparency. i'm guessing its the IconInfo hbmMask + hbmColor properties?
#Region " CreateIconIndirect" Private Structure IconInfo Public fIcon As Boolean
After scouring the forums for a code to extract icon from exe and convert to bitmap, i got that working, and the image will display on my form just fine. I want to save the image so it can be loaded again after the program is closed, but I get "Generic error in GDI+ occurred" when I attempt to save the bitmap.
Dim ExeIcon As Icon Dim button1icon As Bitmap ExeIcon = System.Drawing.Icon.ExtractAssociatedIcon(Filename) button1icon = ExeIcon.ToBitmap() Button1.BackgroundImage = button1icon button1icon.Save("C:utton1icon.png", System.Drawing.Imaging.ImageFormat.Png)
I have a system icon (for example a folder icon) and I want to display it in a richtextbox. That's not a problem, but the transparency of the icon is gone and is replaced by a blue color. I tried to use the MakeTranparent function of the bitmap object, but with no luck. How can I make the bitmap transparent again?
Here is my code:
Dim _mycurrentFolder As String = "C:Test" Dim _folderIcon As Icon = GetSystemIcon(_mycurrentFolder) Dim _folderBitmap As Bitmap = _folderIcon.ToBitmap()
I 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
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've created a new bitmap object and am shading some pixels inside it black using the setpixel function. At the end I do: myBlankBitmap.Save("D:3Didea_out.bmp") Great. Except the bitmap that is saved is 32bit and won't open properly. I want it to be 8 bit. I can't find any options to change the bitdepth.
I knew everything I needed to save an image, so I type in my code, and yet another error pops up. Here's the bit of code: screenshot.Save(CaptureMain.picLocation.ToString, Imaging.ImageFormat.Bmp, "Screenshot")
And, the error's kind of lengthly... Error1Overload resolution failed because no accessible 'Save' can be called with these arguments:
'Public Sub Save(stream As System.IO.Stream, encoder As System.Drawing.Imaging.ImageCodecInfo, encoderParams As System.Drawing.Imaging.EncoderParameters)': Value of type 'String' cannot be converted to 'System.IO.Stream'. 'Public Sub Save(stream As System.IO.Stream, encoder As System.Drawing.Imaging.ImageCodecInfo, encoderParams As System.Drawing.Imaging.EncoderParameters)': Value of type [Code] ..... The variable 'screenshot' is a bitmap.
I'm having an issue with some code I'm trying to write that takes a screenshot of the current screen and saves it to a bitmap file on my local PC.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim tempScreenshot = New Bitmap(Screen.PrimaryScreen.Bounds.Width,
I created a paint type program for signatures, and now I would like to save my canvas as either a jpeg, bitmap, or gif file, but I am unsure how to go about this. Here is my code,[CODE...]
In the below code I load the image to the graphics path using resource image and adding text on it. When I add the image through open file dialog it paints on the form with original size but I need to resize it, add it to the PictureBox, add text to it and give zoom and pan options to it and then I need to save with the original size.
When I resize and when save the image I endi up with a small image.
Here is my code:
Imports System.Collections.ObjectModel Imports System.Drawing.Drawing2D Public Class Form1
I have the following code found on internet: Const WM_CAP_START = &H400S Const WM_CAP_EDIT_COPY = WM_CAP_START + 30
'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:
'---save the video data into the Image global variable--- Public Sub CaptureImage() Dim data As IDataObject Dim bmap As Image Dim ms As New IO.MemoryStream() '---copy the image to the clipboard--- [Code] .....
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.
Im having some problems when trying to save an icon from resources.Im using the following: My.Resources.setup3.Save(Application.StartupPath + "\temp.ico") But that generates the following error: QuoteValue of type 'String' cannot be converted to 'System.IO.Stream'.
I've written a program that adds an image to an imagelist, with a transparency color set, and then saves it as an icon.it works + the image is saved with the proper transparency, but windows doesn't recognise my icons as icons. i've tried 2 ways[code]...
I want to save the fav icon in the each page i have navigated to. because i have a bookmark field where each bookmark is a .url file. and i want the icon to be the fav icon of the page it has saved. ( if i got one saying "Dreamincode" with "www.dreamincode.com" inside it then i want to save the icon of www.dreamincode.com )the name sould be the url. So i can use "if file.exist" becuase otherwise it will add a new icon for each image of items the site contains.
i trying to do a file upload, i want to image to save to image folder, however, the image don't know appear in the directory that i indicate if i click on "show all file", the image appear, but the image icon is blank or white like the image below show so i click on that image and click on "include it in the project", however, it shouldnt be the case that i everytime upload an image,i need to redo that again so how should i allow don't appear the white icon and to always appear in the upload folder when i upload a image instead of manually click on the image to include in ? is it visual studio problem? does i need to click on something to make the white icon disappear? [code]
What the icon file filter is for load/save file dialogs. (I know the jpeg one is "JPEG Files (*.jpg)|*.jpg|PNG Files (*.png)|*.png|BMP Files (*.bmp)|*.bmp|All files (*.*)|*.*" But as far as I know you can't use these as icons without an icon editor).

this is my code
