At least experimentally, embedding the manifest did fix things and in expected ways.
Without opting-in to being DPI aware Windows APIs return system metrics as though you were running at 96 DPI and then do the scaling post-render. This would still cause similar problems with raster fonts. With the embedded manifest the text and menu appear crisp, and the bitmap images in the toolbar appear small because they're being displayed with the resource height. A more complete fix for this would include providing multiple image resources or basing the toolbar height on a system metric, but for day to day work this has made gVim better for me. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Alessandro Antonello Sent: Thursday, March 26, 2009 2:54 PM To: [email protected] Subject: Re: Feature Request: Dpi awareness on Windows I don't believe that the manifest could change anything. The problem happens in my system too, and is not linked with DPI changes. I just used 96 dpi and the text drawing by Vim has the same problem. One key that we must think about is how Vim calculates the font size to accommodate columns and rows in a buffer window. I don't have the Vim sources so I can't answer that question but Windows has only one way to measure a font height and that way is pixels. But we always set True Type and Clear Type font sizes in points. I think that this calculation is made in the right way by GVim, since is very simple. But just this does not work with some fonts. If you get Liberation Mono font, for example, the result is very similar in GVim and Notepad, but not in UltraEdit 32. In other way, raster fonts are much better show in GVim than other known editors. For this two considerations I came with the conclusion that the difference has in the calculation of the font (and characters) size. I also saw this difference between how the fonts are shown a few years ago. But I never pay to much attention on it. I solved the problem looking for a better font to work with.
