View 3 RepliesInterface And Graphics :: Rip Pixel Color Off Of The Background Image Picturebox ( The Level)?
Feb 27, 2009Ive been working on creating a side scroller game, and the back color of my pictureboxes needs to go. when transparent, it shows through the program and onto whatever is active in your Windows os(usually Visual studios).
I am trying to rip pixel color off of the background image picturebox( the level), and replace parts of the character picture box that show transparency with the level art. there may be poor logic in my code?
Heres my code:
Dim newImage As Bitmap = New Bitmap(PictureBox1.Image)
Dim backImage As Bitmap = New Bitmap(PictureBox2.Image)
Dim ximg As Bitmap = New Bitmap(PictureBox3.Image)
[code]....
not the best idea, but all i get is one color for all the level pixels placed in the new image, which is odd. any poor logic you see in this code that could allow the newImage.setPixel not to be 1 color? when i breakpoint, it is recieving different colors from the backimage.getpixel, but only putting one shade on for setpixel somehow. im not going for an accurate color read from the background yet, just wondering why im getting 1 pixel color for the whole picturebox background when being changed.

If there is an error then the screen goes all grey. What I want to do is, if this does happen, display an alert message like - "An error has occurred
View 3 RepliesLoad A GIF File, And Start With The First Pixel And Check To See If That Pixel Color Is Closer To Black, Red, Green Or Yellow?
Jan 30, 2009I would like to load a GIF file, and start with the first pixel and check to see if that pixel color is closer to Black, Red, Green or Yellow, then take what ever color it closest matched to and output that color as a number, 0, 1, 2 or 3. So just for a small example a 5x4 GIF would be converted to something like this: 0112223322220111332?

May 3, 2011I would like to create a pixel viwer (i.e. zoom into a picture to view the image's pixel information - Similar to windows paint or Photoshop). I have created an image zooming code, but it enlarges the image and sadly, doesn't show the blocks of pixels I was hoping for.I have thought of several ideas, but each worse than the next. As an example, re-create the image, increasing each pixel's area based on the zoom-level. But I can tell already that this process would be slow and judging by photoshop (or paint) there is a quicker method.

Nov 1, 2009I am developing a software that would scan the image in a picturebox and obtain the rgb values of each pixel in the image and convert each rgb values to HSL values. I am using vb 2008 express edition. I am still a student. All I have done is to obtain the image in a file and paste it in the picturebox. Below is my code. I dont really know how to start with the process of obtaining the rgb values of each pixel and converting them to HSL values and averaging the HSL value.[code..]

Nov 24, 2008I made a graphics program in VB6... I then wanted to remake it in VB.NET (I believed it would be faster).
To convert it I wrote both the VB6 and VB.NET versions from scratch side by side. What I have found it that the VB6 code is MUCH faster than the VB.NET program... which I can't understand... (Please note that when not rerendering it in VB.NET it is much faster than VB6)
Here is the VB6 code

How do you do this in VB.NET?
EDIT: Also... why do I have to multiply Me.ClientSize.Width by 3 for it to be the right size... it doesn't seem to add up.
EDIT2: The smaller the radsize the more efficient VB.NET is compared to VB6... so perhaps it has something to do with the setpixel in VB.NET
Find A Pixel Color On Screen?
Aug 24, 2009I'm trying to figure out how I would find the color of a pixle.
Say I wanted to find RGB(255, 255, 0) and get the X, Y, position of it, how would I do that?
I was thinking of a loop with BMP.GetPixel, but I wouldn't know how to check. It's not compatable with RGB.[code]...

Sep 24, 2008how I could search a given bitmap, say "test.bmp" or a printscreen, for two pixels that are next to each other and that have specified color values? The colors are: &H486596 and &H213D66. I then want to return the pixel positions in the image at which they are first located adjacent to one another. I'm only after the first instance of the occurrence. I wish to use GetDIBits as I hear that it's quicker. So I want to find the first instance where the color value for pixel (x,y) = &H486596 and (x+1, y) = &H213D66.

Build Graphics And Try Different Colors For Pixel Location?
Aug 6, 20091. Is there either a program or a way of using vb.net where I can load an image and get a reading of every hexadecimal value for every pixel location in the image? Quick example, sometimes, I'll load an image into Microsoft paint and I try to determine which colors are being used in certain locations of the image but all I can do is guess.
2. If it is possible (especially using vb.net), is there a way to build an image by manually coding hexadecimal values for every pixel location, then, saving the image? The thought here is that I can build my graphic and then try different color schemes until I'm happy with its presentation.

View 3 RepliesGet Pixel Color Of Label?
Oct 8, 2009I am creating a custom tooltip label. My problem is auto resizing it (particularly height).The thing to note here is that the label i am using is an infragistics label, and i can have different fonts and formatting inside the label which means i cant just measure the text height based on the font because the label will contain multiple fonts.The only thing i can come up with is to make the label the height of the screen, and then perform a loop which scans the colour of each row of pixels starting from the bottom, decreasing the label height each time until it finds some pixels which <> the backcolor of the label (which would indicate that there is some text there).This is the only reliable way i can think of to make this happen, but im having trouble finding out just how exactly to get the color of the pixel at the given point.I did find one method of getting the pixel color, but the problem was that it when i requested it in the form_load it didnt return the right color because the screen wasn't painted (i guess).
