I'm trying to debug some code and now I'm lost. Here's the problem. I have a graphic editor with which I can draw shapes and other graphical items.

Posted by nik NO[at]SPAM email.dk at 1/7/2005 6:46:00 AM
I would like to use the method DrawString(string,font,brush,x,y) to draw a string. The string should be drawn with a certain font and should also have a two pixel border around each letter. My idea so far is to draw the string twice first in a large size and then again in another color and a bit...more >>

GDI+ DrawString space between words
Posted by Giedrius at 1/7/2005 6:35:01 AM
Hi, using DrawString, MeasureString works not as it should on my WinXP SP2+.NET1.1 latest SP. On Win2003 works fine. Problem is that same text in a owner drawn grid is drawn with different spacing between words. It looks like below (same text just first ends with 1, second ends with 12): "So...more >>

Can I make a greyscale Graphics object
Posted by Teis Draiby at 1/6/2005 2:17:48 AM
I am working on a painting program for painting height maps. I want the height information to be a 8 bit greyscale value. When I use the Graphics.FromImage() method it seems that I can only create Graphics objects from color bitmaps, not indexed/greyscale bitmaps. Can Graphics objects only be ...more >>

How are several Invalidate() calls processed???
Posted by Teis Draiby at 1/5/2005 6:16:25 PM
What happens if I call the Invalidate(Rectangle) method several times between two OnPaint() calls? - is the resulting invalidated rectangle then added together from each Invalidate(Rectangle) - or are the calls queued to be executed later by one OnPaint() per Invalidate(), causing an overhead i...more >>



printing rotated WMF
Posted by Andrew Deren at 1/5/2005 1:55:04 PM
I'm trying to print some stuff with GDI+ and also a wmf image on the document. The wmf image is rotated 90 degrees, but it looks really bad when printed. When it's not rotated, it looks fine, but when rotated it looks like it is pixelated. The edges of the lines are really jigged. The other stuf...more >>

Folks, From googling I can see this has been asked numerous times yet I am unable to find an answer: How can I create menus similar to MS Outlook? Specifically, the gradient menus. I've found and implemented gradients in the menu items themselves but have not been able to figure out the gra...more >>

PictureBox Problem
Posted by subdueme NO[at]SPAM hotmail.com at 1/4/2005 3:55:35 AM
Hi No, I'm not handling any picturebox events. I think, it does not happens with all images... If you're creating graphics inside the picturebox it seems to behave correctly but when I use picturebox.image = image.Fromfile() the image flashes everytime I enter or leave the picturebox... I don...more >>

GDI+ Turning off AntiAlias
Posted by semhelp at 1/3/2005 9:41:02 PM
Is there a way to turn off antialiasing? I've tried smoothingmode.none, but it doesn't help. I need to draw 2 rectangles (using a hatchbrush) that have some overlap. I'd like the result to appear as if single polygon was drawn. With the antialiasing, I get a different result where the...more >>
