Interface And Graphics :: Rip Pixel Color Off Of The Background Image Picturebox ( The Level)?

Feb 27, 2009

Ive 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.

Interface And Graphics Image Pixel Viewer

May 3, 2011

I 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.

Interface And Graphics :: How To Obtain Rgb Values For Each Pixel And Converting Them To HSL Value

Nov 1, 2009

I 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..]

Interface And Graphics :: Speed Difference From VB6 - In Pixel Rendering

Nov 24, 2008

I 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

[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

Interface And Graphics :: GetDIBits : Return The Pixel Positions In The Image At Which They Are First Located Adjacent To One Another?

Sep 24, 2008

how 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.

Interface And Graphics :: Lots Of Data To Handle - Locate A Tile In The Map When It Is Clicked?

Jan 31, 2011

My tile-based map editor project. So far, it works really awesome. Here, look at a picture: [URL] And the screenshot is outdated: Now I got the Pencil, Rectangle and FloodFill tools too!, the tilesets are from that popular (well, not so popular) game engine called RPGMaker.

Currently, this is how the map is structured:
One ArrayList represents the X coordinates.
One ArrayList in each X represents the Y coordinates.
One ArrayList in each X,Y represents the tile.
The tile is an ArrayList containing three elements:
The Image name (Tileset01 in the screenshot), the X coordinate in the image, and the Y coordinate in the image. Those coordinates are from the TILESET01 image, not map.

Getting the idea?
How do you locate a tile in the map when it is clicked?
First I get the cursor's position on the map picturebox, then convert it to a multiple of 32 (the tiles are 32x32, yes), divide the position X and Y by 32. The results are the indexes I need to get to the tile I clicked.

That method works just fine for me.

When the map picturebox invalidates and needs painting... When that happens, I iterate through each X and Y arrayList. When I get the arrayList that represents the tile, I use it to draw on the map.

For example:
Iterating X arrayList.... step 8......
Iterating Y arrayList..... step 3.......
Found arrayList with three elemetns: ("Tileset01",32,96)
Draw image on the map picturebox, source is "Tileset01" on rectangle (32,96,32,32)... draw it on map picturebox's point (8 * 32) and (3 * 32)

And so on.

Now you understand how I am working with my map editor, how I am locating clicked tiles, and how I am drawing it. Everything goes fine, except for one problem: At some point, the user might want to make a 500x500 map.

That means, an arrayList with 500 elements representing the X tiles. Then an arrayList with 500 elements for each X tile, representing the Y tiles. Then an arrayList in each X,Y pair.

Then multiply that result by 5, because there will be 5 drawing layers. How am I supposed to handle such huge maps?! My app explodes when I set the map dimensions to 500x500! 500x500 is the max setting allowed in my app. I also know that 500x500 map editors are possible, because I have seen others before. With great performance.

Interface And Graphics :: Clearing All Drawings In PictureBox?

Apr 5, 2012

I've problem with clearing all the drawings I've created in my PictureBox. In fact I've created animation which stops after certain time and remains on the screen. The animation is created/painted with collection of about 25 TextBoxes - input of a user. Now I've added a button which clears all that info in TextBoxes and also should clear PictureBox -ictureBox.Refresh(). The problem is when I add new info in 25 TextBoxes nothing appears in PictureBox and I can't start an animation. Wondering why...

Interface And Graphics :: Get The Button To Look Like Default After Changing The Color?

Aug 26, 2011

I have a form with buttons, and the user can change the colors of the buttons with the color dialog box for fun:

Button_Play.BackColor = ColorDialog.Color

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:

Button_Play.BackColor = Button.DefaultBackColor
Button_Play.BackColor = SystemColors.Control
Button_Play.BackColor = Color.Empty

I am using VB '08 Express on Win XP with the Desktop, Display Properties, Appearance, Windows and Buttons: set to Media Center Style and Color Scheme: set to Energy Blue. how to (with this theme) get the button to look like default after changing the color?

Interface And Graphics :: Animated Gif In Picturebox, Slow & Choppy?

Apr 3, 2009

I've been searching for days. I can't find anything that I think is going to work. I've probably read the answer and skipped it because I don't get it. I'm new. I've researched multithreading, sub routines and webbrowser. The webbrowser thing doesn't seem professional to me.

All I want is the animation to be smooth when it's displayed and to have it integrated into the app so it's not called from the local drive.The animated gif is in PictureBox3. Please point me in the right direction. I really don't want to use a static image.
