It would appear that you have encountered some kind of keyboard malfunction. I suggest you fix this first and then come back here to ask your questions.

It happens when you drool all over the keys. They get all gummed up.

That's what happens when you drool on your keyboard, you end up gumming up the keyboard. I think this is what they mean by sticky keys.

Sounds more like 10yr old to me.

You think they don't drool?

then you should call it in form "constructor" not "Form Load event"

instead of making a byte[] why dont you do your editting directly to the bitmap and then use the bitmap save function create the output file you want

well then you dont want to be working with an array of image pixels cuz they will always be valid values
Whats you error?

Hi Collin,
Not every stream/file constitutes a valid image; what Image.FromStream() accepts is the streamed content of an image file, as Image.FromFile() would expect. There is more to an image than just a bunch of RGB values; it needs dimensions, pixel depth information, maybe a color lookup table, compression information, etc.
Now what is it you want to achieve? You already have a valid image to start with, so why not modify it rather than copying/modifying its pixels, then work from there.
FYI: setting every third byte to 255 produces red only if (1) you do have a 24bpp image (which would be exceptional, most .NET images are 32bpp) and (2) the image is sufficiently dark (a white pixel will remain white, a yellow one will remain yellow)
BTW: in general when getting an exception, you should look at it; when posting a message, you should report it, that could help getting more and better replies sooner. In this particular case, you were bound to get an ArgumentException telling you not much except the one argument wasn't good enough...

Hi Collin,
if you want to convert an existing image into a stream, use an Image.Save overload that deals with streams i.e. Image.Save(Stream, ImageFormat).
the code you have shown does NOT deal with an image, it only handles pixel data; I suggest you don't try and convert pixel data back into a valid image, just use the existing .NET classes (Image, Bitmap), they know about several image formats.
FWIW: if you are having trouble turning an image into a stream (say a MemoryStream), then reading it back from that stream, chances are you forgot to "rewind" the stream between writing and reading, i.e. to reposition it at its beginning.

You can use the System.IO.MemoryStream object to do this.
byte[] buffer;
MemoryStream ms=new MemoryStream(buffer);
Hope this helps.

Hi,
I am trying to get some rich text (from a RichTextBox.Rtf) onto a bitmap but can't seem to find a way to do it.
The key lines of my code are...
Bitmap Canvas = new Bitmap(200, 200, System.Drawing.Imaging.PixelFormat.Format24bppRgb);
Graphics Artist = Graphics.FromImage(Canvas);
Artist.PageUnit = GraphicsUnit.Pixel;
Artist.DrawString("Hello", descFont, descBrush, rect, descFormat);
It would have been nice if there were a:
Graphics.DrawRTF(string richText, Rectangle rect)
method, but there isn't.
What is usually done as a replacement? Any help or pointers appreciated.
Regards,
David Bailey.

Hi musefan,
I am trying to display RichText not plain text. Or are you saying that the DrawString() command handles rich text as well?
-David.
|
|
|
|

No, DrawString() will not auto handle your formatting.
Have a look at this[^] for some ideas.
You could always handle yourself by iterating through each word in the richtextbox then getting its formatting(color, font etc.) before drawing it to the graphics object.

Thanks.
I did not think to loop though the rich text. Might just do that.
The link was useful too.
-David.
