What i'm trying to do is fill a non rectangular region (actual build up out of 6 points) and draw a bitmap in such a way that it stretches with the region. Now for drawing a normal bitmap or even a trapezoid bitmap there are examples on the net. but drawing anything more then that with GDI+..

View 3 RepliesI need to write a code to find identical adjacent pixels in a bitmap image. It should work as the 'magical wand' in Photoshop. My images are always black and white (white background with car parts drawed in black). Given the x,y coordinate for a single black pixel in the whole image, the code should find (and paint with another color, say red) all other black pixels that are linked to that one, and so on, until all linked black points will be painted in red.

All other parts will remain black. Does it make sense?At the end, there are two pictures (before and after) to help understanding what I need to do to the images.I tried a simple 8-pixel adjacent approach for every pixel (starting on initial coordinate) but it turns out into a very stupid and endless looping algorhitm.

View 6 RepliesWhat I'm trying to do is iterate through each pixel in a bitmap, and get the color value of each pixel.I've tried using .getpixel, but it's fairly slow. On a 640x480 image, it takes roughly .35 seconds to go through it. Which can add up if doing many pictures.

There is a reset button to put the colors to how they were without any special coloring, but I can't get them to go back to how they originally looked.They go to gray in the middle, instead of the nice shaded blue/gray style. I have tried a few different things:

Any recommendations? I like the fact that 255,255,255 is white. Is there a way to create color by combining three colors that were made from argb? I may just have to make my 20 different colors set and then refer to them.

View 1 RepliesIve 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.
I'm trying to figure out some simple code to detect when a pixel changes color anywhere on the screen. Maybe with just a msgbox popup when it changes.

If you have a separately declared PUBLIC INTERFACE and then IMPLEMENT that INTERFACE.
1) My general question: Is an INTERFACE simply a means to ensure that a CLASS implements all the methods defined in an interface and to ensure that they can only be implemented once?
I have noticed that a method that IMPLEMENTS an INTERFACE method can still have overloads though. :-)
If so, when combined with INHERITANCE though I believe I can finally see the use for defining an INTERFACE!!
2) Do you have to use an interface when linking to a VB6 project ( is this via Component Object Model or COM ) and if so, do any attibutes need to be applied when doing so?
Here is a code snippet.
creating a PUBLIC INTERFACE outside of any CLASS. I guess this would not normally be done from an OOP point of view?

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.
