[Bug 20420] New: VB6 Font size problem with custom usercontrols
http://bugs.winehq.org/show_bug.cgi?id=20420 Summary: VB6 Font size problem with custom usercontrols Product: Wine Version: 1.1.31 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: oleaut32 AssignedTo: wine-bugs(a)winehq.org ReportedBy: gabmoa(a)yahoo.it Created an attachment (id=24231) --> (http://bugs.winehq.org/attachment.cgi?id=24231) Test VB6 wrong font size There is an important issue with font size with VB6 applications. I adjusted some VB6 applications from xp to linux using wine and the major problem consists of something wrong on saved font size. The test application has a label with a tahoma 14 font and the same saved in a usercontrol with a property bag: in windows the two labels have obviously the same size but not in wine! On load event font name and size are printed on the respective label: It seems the property value is right but font is not! -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Does it help if you copy tahoma.ttf from Windows over a Wine one? No. I have done some tests and the problem seems indipendent from font. (I think the importance may be normal because in some application I have tested the font is so small (it depends from fonts used) that it's not really usable)

The bug occurs when you try to change the font at run-time using the object's font object property. (I'm currently using Wine 1.0.1, but I've seen it on previous versions too) There might be a chance to hack the bug somehow using Windows font API (that's my guess). But generally I solve it now by avoiding changing this "font" property at run-time, instead making out with just RTF selfontsize/selfontname properties... (I'd confirm the bug by changing the status to "New" if I could) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I think, that the bug should be fixed even if it affects only the legacy VB6 apps, since there are many really good/useful VB6 apps, that people are using and will continue to use, that are too large and too complex to be upgraded to VB.net. And such combination as Wine+Linux might be the only ones to still support these Windows apps in future, since we already know Microsoft's statement not to support these apps beyond Windows7 OS. The fonts are so far the most buggy part I've seen in VB6 applications on Wine. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The font on several screens is displayed too small and it's difficult to read. However, when I switch to native oleaut32, the games become unstable and are prone to crashing where they had not before. I have screenshots of the text with both native and built-in if I need to post them. It would be a huge benefit to have this fixed, as the crashes with the native oleaut32 make the games almost unplayable. These aren't "legacy" apps, either, as the new Total Extreme Wrestling 2010 is being released on Monday, with the pre-release demo already available. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

The problem still exists, but the recent changes to the builtin oleaut32 seem to have worsened the font issues. I also tried running this program using a Wineprefix that had Tahoma installed via Winetricks, and other than a slightly smoother font for the larger line, it looks pretty much the same. The font seems to have lost its thickness, something that I also noticed in Total Extreme Wrestling 2010. Native oleaut32 still displays the font with the normal size and thickness. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Fixes font scaling in oleaut32, and hopefully http://bugs.winehq.org/show_bug.cgi?id=20420. The factors leading to tiny unreadable fonts include 1. Poor font selection in the first place. Please don't even try to use 8 or 9 point fonts. 2. Badly behaved Ole components that don't call SetRatio to set the screen resolution for the fonts they use. 3. olefonts.c hard coded a default screen resolution of 72 dpi. The crux of this patch changes the hard coded default resolution in OLEFontImpl_Construct from 72 to 0 dpi. Apps that call SetRatio override this. Apps that dont, well the maths used to calculate the desired font size then calculates a font size of zero. Windows (or Wine) will not render a zero point font, but will select a reasonable size to use instead.

Now that I think about it, instead of making the default zero, it might make more sense to just increase the default value from 72 to 96 or something, whatever is more typical for a modern display. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
