[Bug 33190] New: Font display problem using text and dc rotation

Bug #: 33190 Summary: Font display problem using text and dc rotation Product: Wine Version: 1.5.25 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdi32 AssignedTo: [email protected] ReportedBy: [email protected] Classification: Unclassified

We recognized an gdi text display issue using the application Gausz http://appdb.winehq.org/objectManager.php?sClass=application&iId=13649.

The problem appears when gdi text is drawn with font rotation *and* display context rotation.

The problem do not appear when either font rotation or display context rotation is zero.

The application uses CreateIndirectFont to set a fixed size font with optional set rotation and draws the text with TextOut(). The display context rotation has been set with SetWorldTransform().

We tried to find a test case application, but where not able to reproduce the problem outside the application. We also tried to debug into wine's code based, but got lost by the details.

From my observations I would say that there is something wrong with the advance

of the character origin vector, seeable on the '6.0' or 'DN 200' text.

Most gdi functions, including text, don't properly support GM_ADVANCED yet.

Can you explain a bit more what exactly is not working with gdi text display and which part of the implementation is covered ?

The screenshot shows that dc rotation works fine at least for lines and rectangles.

Most gdi functions, including text, don't properly support GM_ADVANCED yet.

One problem with rotated text display seems to be in the implementation of GetTextExtendExPointW(), which output differs between windows and wine (beside the general scaling and rounding differences)

Looks like that wine use the rotation from the world transformation matrix, while the windows implementation do not use this rotation.

Please don't change the original reported version, it's supposed to be the oldest version where it was tested.

Any chance to add a related tooltip to the version field as available for other fields ? This would make developers live easier. Optional disabling editing of the version field for normal users like me would make more clear that this should not be changed.

Comment on attachment 47159 [details] Fix text rotation problem in GM_ADVANCED mode

Patch has been rejected because it does not fix the issue in a general way. https://www.winehq.org/pipermail/wine-devel/2014-January/102440.html

The patch decomposes the translation and rotation from the transform matrix and supports only the case that the matrix has uniform scale and shear and contains a rotation.

It is currently not clear if there is a common usable decomposition algorithm.

Published algorithms limits the implementation to uniform scaling for example: http://stackoverflow.com/questions/4361242/extract-rotation-scale-values-fro...

".. This only works if x and y are always scaled the same (uniform scaling). ..."

Others depends on a specific order of operations on the original matrix

".. QR Decomposition is a much better choice, though it still presents problems. Only when M is constructed by scaling then rotating will QR recover the original factors ..."

Polar decomposition is mentioned as a possible way t http://research.cs.wisc.edu/graphics/Courses/838-s2002/Papers/polar-decomp.p... with the drawback, that there is no explicit shear extraction.

"... As explained earlier, interaction is to blame; shear will be factored as rotation and stretch. As ... show, the appearance of a factored animation can be quite different from that of a direct animation for shear...."

Patch has been rejected because it does not fix the issue in a general way. https://www.winehq.org/pipermail/wine-devel/2014-January/102440.html

The mentioned patch fixes the problem from my experience for all type of gis applications because they do not use different axis scales.

A generic solution would be a refactoring of the code related to font rotation to not use bounding boxes with two points. Instead the code should use a polygon based bounding box describing each corner, which will be rotation save.

Hello Ralf, many thanks for testing and reporting positive results. In the original comment you mentioned that application Gausz suffers from the font rotation issue, is there a chance to test the patch with it as well?

Hello Ralf, many thanks for testing and reporting positive results. In the original comment you mentioned that application Gausz suffers from the font rotation issue, is there a chance to test the patch with it as well?

Hello Dmitry, I applied the patch to wine 8.2.0 and did run the mentioned application.

See attachment 75473, attachment 75475 for the result without the patch and attachment 75474, attachment 75476 for the result with your patch applied.

Hello Dmitry, I applied the patch to wine 8.2.0 and did run the mentioned application.

See attachment 75473 [details], attachment 75475 [details] for the result without the patch and attachment 75474 [details], attachment 75476 [details] for the result with your patch applied.

Ralf, thank you very much for testing. Let me clarify the results a bit: does that mean that the patch fixes all the problems with rotated text for you?
