Well, no, because the file you have, is not a .NET bitmap or image object. If you can save from the ImageFile to a memory stream, you could use that as a point of conversion.

I'm sorry, but I don't understand. You're using the webbrowser control ? You say you've opened a web page ? So, what do you want to do ?

Hello
I'm looking for some Csharp component to display all character of a selected font, allowing selection
Charmap.exe is a good example
It can be very usefull in order to select special character as Webdings, Windings, Symbols or cyrillic . etc
Any idea ?
Thanks for your help

I would try a TextBox (set to multi-line) or a RichTextBox; insert the appropriate characters, and then set the font as required.
Or you could use a whole bunch of Labels  .
|

|

Someone did a similar thing here (can't post the code, I'm afraid) by :
For each char from 32 to 255
create a label with a border, width and height as appropriate, and the font set to the desired font, Text of the char.ToString();
The labels can then be positioned however you want for a pleasing display.
On the click event of the label, it displays the same character in a label using the same font with an increased size, and on double-click it raises a 'CharacterSelected' event which pass back the font and character selected.
Should be enough to get you started?

Yeah, but how can one find out ALL the characters present in a specific font, without looping all Unicode char codes and measuring string width looking for non-zero?

not sure you need to - just display 'em - you'll get an empty box if they're not defined in that font.

I am not going to create a grid with ten thousands of cells, I want to know what characters are present without painting anything.

Sorry - misread/misunderstood.
Yep - you don't want to have a dialog popping up that you have to scroll forever to find used characters... just stick with 33 through 255 if you ask me!

Hello thanks for all reply
I was lookin for an "out of the box" tool
The solution to create 256 labels seems a liitle bit heavy
Finaly maybe using a datagridview can be the right solution ??
|
|
|
|
|
Well, behind the scenes all a datagridview is going to do is to create the labels for you, so I'm not sure why you think it's a bit heavy - it also gives you complete control over your presentation.
I reckon you could knock up the code in 1/2 day easy - then publish it as an article on CP for the glory of it

right now i m using groupbox as a control and line control dll to draw horizontal lines so as to draw glyph in defined area.
InkOverlay mInkoverlay;
mInkoverlay = new InkOverlay(groupBox1);
mInkoverlay.Enabled = true;

That's not exactly easy, and will depend on factors like the number of channels, and the compression level used. If you're using variable bit rate compression, it gets even more complicated.
Ideally, you should start by learning about the mp3 format. A good source of info is http://www.mp3-tech.org/[^], particularly in their "Programmer's Corner" section. I wrote my first decoder based mostly on what I learned there.
PS - if you're writing mp3 software, C# may not be the best tool for the job...
There are three kinds of people in the world - those who can count and those who can't...
