Use Open Type Fonts To Write To An Image In .net?

Jun 16, 2012

Does anyone know of a solution for writing text to an image using an OTF? I know that GDI+ does not support OTF and that WPF does. I can load the font as a label in WPF, but still do not know how I can write this over an image, such as a watermark would do, and save that image.

I need this in an ASP.net page, so I won't actually be able to use WPF, but I figure that might be a start in building a class my page can import.

Fonts On Button Text Image Unreadable ?

Jan 28, 2010

Using XP and VB 2008 Express for development of Widows Forms App.I am setting a button's .text to "" and then assigning a bitmap with some text written on it to the button's .image. Everything looks great on the development compter, but is almost unreadable on test computers using Vista and Windows 7. This despite trying a number of different combinations of (standard?) font family and size (including Arial, Verdana, Microsoft Sans Serif). Why?

Details....I have a button on a form (32 pixels x 32 pixels).I set the button.text field to "". I create a bitmap a little smaller than the button, and DrawText on it (I can't simply use the button.text field because I want to place text in different areas of the button and draw special characters.I use the following code to create the bitmap:

m_bmpDrawingSurface = New Bitmap(30, 30, Drawing.Imaging.PixelFormat.Format32bppArgb)
Dim objGraphics As Graphics
objGraphics = Graphics.FromImage(m_bmpDrawingSurface)[code]...

I wonder if somehow fonts are being anti-aliased or otherwise cleaned up by the system on the development computer, but not on the other computers. I also wonder if I should be creating just a simple 30 pixel x 30 pixel bitmaps, or perhaps should be trying somehow to get the buttons 'device context' or something. Or, is there an alternative to DrawString that draws text more intelligently than just setting the nearest pixel either black or transparent, which is what seems to be happening (ie, no anti-aliasing or creation of shades of gray). Maybe another pen? Is there an "anti-aliasing" pen?

Cast Value Type To Nullable Enumeration Type In Generic Object If All Types Are Unknown At Write-time?

Dec 14, 2011

I have a generic Class I'm using to hold information loaded from a database.I have a method which takes a DataRow as an argument, uses the object's known column name and extracts the data from the DataRow, such that:Dim loadData As T = CType(myDataRow("myColumnName"), T))works as my default assignment in most cases.Unfortunately, due to some horrifying design constraints, some of my columns may be null, and may also be taken from enumerations.This means that when <T> is Nullable(Of SomeEnumeration) the above code does not work because I can't cast 0 directly to SomeEnumeration.Zero.Is there some way to check whether <T> is Nullable(Of [Enum])? Or some way to write a method which allows Integers to be cast to Nullable(Of [Enum])?I feel like I'm forgetting something that would allow me to write one of the other of these, but my weak google-fu is turning up nothing.

EDIT: Okay, thanks to dasblinkenlight's answer below, I can detect when this circumstance is occurring, but what I need to do now is to take a type <T> which I know is Nullable(Of SomeClass), get a type reference to SomeClass and then create a new object of type Nullable(Of SomeClass) and assign that to LoadData.My problem was that I had a lot of difficulty in finding any function which would accept baseType as an actual Type.Parse accepted baseType as a parameter, I knew baseType was an [Enum] type because of dasblinkenlight's code, so I was, in this instance, able to code a solution. It's a solution which is very specific to my problem (i.e., T is Nullable(of SomeEnumeration)), but it's a solution nonetheless.

Write Metadata To PNG Image In .NET

Jul 22, 2010

I see more than a few questions asking how to read metadata from an image, but I haven't seen as many asking how to write metadata. Basically, I need to add one item of metadata ("ImageDescription") to a PNG image I'm generating dynamically (creating a Bitmap object and procedurally generating all the content in it).

What would be the best way to add metadata to an image with .NET either before or just after writing the file to disk?

Write A Programme Where A User Can Type In A 'string' Into A Textbox?

Feb 6, 2012

I am attempting to write a programme where a user can type in a 'string' into a textbox. A data dictionary will contain specific keywords relating to a specific classification, where an algorithm can detect whether any of the keywords occur in the 'string'. Here are the processes that need to occur:

1) A data dictionary, that contains keywords relating to specific classes eg. (IT Issues, Printer, Software, Password).

2) An algorithm needs to compare the words in the Data Dictionary to that of the 'string' to detect any matches.

3) A rule set to determine what classification the 'string' needs to be classed as.
