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?
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?

View 2 RepliesEvaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?

Nov 23, 2011I am working on a WPF application and I am looking to retrieve the color value of a pixel on the screen (the screen being the Window that my application is displaying).I have found a tutorial that shows how to do this using the gdi32 API but since this is a WPF application I am looking for a way to do this without using GDI.

Set Pixel In Some Container?
Feb 2, 2012VB 6.0 had a Set Pixel function, which is not available in VB.net. using a draw ellipse function with parameters specifying a circle one pixel in diameter.The above is painfully slow.I have been drawing graphics in a Bit Map using a Set Pixel function & then copying the entire graphic from Bit Map to a Picture Box. This results in nothing seeming to happen for several seconds & then the entire graphic is displayed in the Picture Box.
The above does the job, but it would be nice to display the graphic as it is being generated pixel by pixel, which was possible using VB 6.0, Might there be a Windows 7 API which would set a pixel? Might Microsoft be considering a Set Pixel function for Picture Box graphics?

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).

I need this so I can make a little bot that automatically pushes buttons for a online game called "JamLegends"(http:jamlegends.com). Its kind of like Rock Band, and if I can grab the color, then I can simply used 'sendkeys' to press buttons to make the bot work.
Edit: This is for a project in school. We need to make something that will make a program that will make something easier to work with or use(In my case, JamLegends). I have nothing to work with, I've researched a bit but I found nothing that can grab pixel color values.
