gdi+

Have not done this before ( except in java , look how Steve McLeod fixed it), so obviously I suck at it. Here 64 pixels around current mouse position get drawn little bigger on a form. Problem is, that it's 'kind of' to slow, and I have no idea where to start fixing. Besides that, I made a timer thread, that constantly calls update graphics when it's finished and a little fps like text, to show really how fast things are drawn. Image example: (Image is from letter 'a' in "IntelliTrace" in Microsoft VS2010) Source example: using System; using System.Collections.Generic; using System

It look desceptively easy to use System.Drawing to create thumbnails in your ASP.NET application. But MSDN tells you : Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions. I'm seeing intermittented 'out of memory' errors within this type of GDI+ code. I'm beginning to suspect this is the cause. How ARE people doing server side image manipulation? Can anyone recommend any

My problem: I'm currently working on a custom user control which displays pieces of text (each with a potentially different font) on one line. I'd like to align all those bits of text exactly along a common baseline. For example: Hello, I am George. ------------------------------ <- all text aligns to a common baseline ^ ^ ^ | | | Courier Arial Times <- font used for a particular bit of text 20pt 40pt 30pt Because I haven't found any GDI+ functionality to do this directly, I came up with my own method (outlined below). However: I wonder if there really isn't an easier way to get this done? My

Before I pass a string to Graphics.DrawString(), I'd like to know exactly where each character will be - not just it's offset and width, but its exact bound box with ascent/descent figured in so that I can do collision detection at the character level rather than using the entire line-height that Graphics.MeasureString() is giving me. I can't seem to find any examples for this that accurately return the bounding box for each character. How can this be done in c#/GDI+ ? Ideally, I'd like to get each of the gray Rectangles as in this image: I don't think it's possible to accurately measure

When GDI+ came out, I remember all the brouhaha about how it was the "new, faster, better" way to display stuff in Windows. But everytime I looked at it, it seemed to me that it was really just a COM wrapper around GDI. Is that true? Or is GDI+ really an independent graphical library that simply shares some paradigms with GDI? Personally, I'm not sure how it could be independent, but I never saw a definite statement one way or another. Ian Boyd Many GDI functions are accelerated by the graphics hardware, and some GDI+ routines may use GDI underneath. But most of GDI+ is independant of GDI. An
