View 8 RepliesBitmap Effects (Firmware 2.0) Change The Source Of An Image In WPF
Sep 2, 2009I think that changing from WinForms to WPF just because the blur effect is easier to do in WPF is the stupiest thing i can do right now it took me time to understand how the windows form application works i dont even how change the source of an image in WPF so here we are again. how to blur a speciefied image using CODE ONLY ?
See what im trying to do:
1. Imagine that you turn on your pc. takes some time to load.
2. Finally for the first time you are on the desktop.
3. Before you do something after every icon is loaded my program
takes a picture of the desktop and blurs it.
4. then it runs fullscreen showing the desktop behind as blurred and
not giving you access to the desktop.
5. a login/register border pops up
6. if you login the program closes if you dont it stays there
waiting for you to login or register.
I wont use it that way im planning to do it on the startup of my program only blur the window not the screen (i mean the content of my window) untill you login or register then it clears again. What i need to learn:
1. How to take a screenshot of my program (only yhe content of the window) [Progress: 1% (cause i know how to take a screenshot of the desktop)]
2. How to blur that image [Progress: 100%]
No need for third party programs or dlls i mean isnt there a default function in vb.net the stupiest way to do it?
Change Cursor Image On Form
Jan 6, 2009I am currently creating a program that will change the cursor's image and let it stay like that until the user clicks use default image button. I do not mean like
Me.Cursor = New Cursor("C:\cursor.ico")
I mean as in even if the user's cursor leaves the form, it will still display the custom cursor only.
I have got only this much done so far, and the code is not 100% working either.
Private Sub ChangeCursorButton_Click()
System.Windows.Forms.Cursor.Hide() 'only hides the cursor when your mouse is on the form, need to fix that
Me.Cursor = New Cursor("cursor.ico") 'had no choice but to use this for now, even if when your cursor is out of the form it will revert to the original.
[Code] .....
The code only works if your cursor is on the form. If its not, it doesn't work as intended.
I need the code to work that the cursor will hide the original cursor and let the custom cursor I declared shown.
Change Image In Windows Forms App. System.Drawing.Bitmap In A PictureBox
Jul 19, 2010I have a VB.NET Windows Forms app with a logo image on the form as a System.Drawing.Bitmap inside a PictureBox.I used the Visual Studio Designer to add the logo .bmp image so I don't currently have any VB code doing anything with it.I'd like to make the current logo a clickable object/button so when I click on it a file browser dialog opens and I can select a new image to replace the current image.The current image is a local resource and is set in a PictureBox as a System.Drawing.Bitmap.How would I replace that System.Drawing.Bitmap with a file selected from the file browser dialog?

16 Color Bitmap Image And Interpert?
Apr 2, 2010I need to read a bitmap generated with paint or similar programs and interpert the picture to detect straight lines of black, larger squares in red and smaller squares of yellow, green or red. Which one of the Visual Basic environments are is best suited for this? WPF or Forms or..The lines represent walls and for start we have square objects as obsticles. I would like to create a maze and allow a dot to travel between obstacles leaving a trace of pixels and not hit any of the objects untill it exits.
I like to write the logic for it but I do not know how would I read a 500x500 pixel picture and decode the colors of each pixel. I like to assign a byte for each pixel's color (256color) but only use 4 bits of it to for start.
I am doing this as hobby. So please forgive me because I should only look at your answers during my free times.It will take some time before I could see it and mark your work as Helpful or Answer.

View 1 RepliesBitmap / Image Manipulation Effects / Methods?
Apr 18, 2012Back when I used to use an 8 bit home computer I dabbled in machine code with an old version of BASIC which allowed you to POKE values into memory and then call the 1st memory location to execute that code. I used the equivalent HEX values for the processor which ran a series of ROR ( ROtate Right ) or ROL ( ROtate Left )commands through the carry bit as each line of the bitmap consisted of a series of bytes which were an 8 bit BYTE followed by the next BYTE in memory. The effects that I manage to create "in assembly language" as it were:
Scroll leftScroll right By manipulating full bytes in memory I created routines to:Flip the image horizontallyFlip the image verticallyTurn the image upside down Anyway, if you were to try this with the BASIC equivalent to GET and SET pixels, obviously the BASIC was a LOT slower. I am also interested in creating animated bitmaps from one or two images such as the following:Page turn effect.Sliding-in of an image in any direction.Ripple effect.Scratch effect.

How To Create A Bitmap Image Using A Text File
Jan 9, 2010I am trying to convert from a text file to an image(bitmap) file.
For example, test.txt: 01 23 34 56 78 90

The first step will be reading the data, so I created some VB codes:

openFileDialog1.Filter = "Text Files (*.txt)|*.txt"
openFileDialog1.Title = "Select a text File"
' Show the Dialog.
' If the user clicked OK in the dialog and ' an image file was selected, open it.
If openFileDialog1.ShowDialog() = DialogResult.OK Then
' Open file.

VS 2008 Small Bitmap From A Larger Image?
Dec 17, 2009I am trying to get a small bitmap from a larger image. something like

However this just gets the entire picture not just a portion of it, I would like to do something like this where I can specify the starting and stoping points
Dim bmp As New Bitmap(PictureBox2.Image, StartX, StartY, EndX, EndY)
I would also like to take these smaller images and paste them into a single larger image. Is there any way to paste it in starting a a certain point. Such as
paste bmp into Picture1 (StartX, StartY)
Change Pixel Offset Of Source Bitmap?
Aug 18, 2009I've got a function that's supposed to extract and return a 32x32px bitmap from a larger bitmap which has a set of 32x32 tiles inside it.
Here's the code I have now, but it's wrong since the Tile.GFX_Pos properties are telling it where in the destination image to draw, not where in the source image to draw from.

So since this doesn't work, what I'm wondering is if anyone knows a good way to select where in the SrcGFX bitmap to blit from, instead of (as currently and incorrectly) selecting where in the destination bitmap to blit to.
