Description Luke 2016-11-09 08:37:32 UTC
Certain images are rotated 180 degrees when view with the OpenGL Renderer. 

Steps to Reproduce:
1. Make sure Tools->Options->View->"Use OpenGL for all rendering" is checked
2. Open the bug doc with a recent build of Writer

Actual Results:  
Image is flipped along horizontal axis.

Expected Results:
Should display normal.

Reproducible: Always

User Profile Reset: No

Additional Info:
Using tinderbox builds, I was able to narrow the range of this regression to:

Created attachment 128607 [details]

Note I could reproduce this bug with both my Intel HD 5000 and Nvidia GTX 650.

vcl: read image from JPEG one scanline at a time
When reading an image from JPEG file we allocate a large buffer
to hold the whole raw image before we read it into SalBitmap.
If the image is large this step will spike the memory usage.

This changes reading so that we allocate only the buffer for
a scanline and read one scanline at a time.

which is the same commit as in bug 103351

Comment 4 Luke 2016-11-09 09:46:11 UTC
Xisco Faulí if it's a duplicate, why am I only seeing the regression start at 11-04? Also no mention of OpenGL in bug 103351.
Comment 5 Xisco Faulí 2016-11-09 09:54:04 UTC
I don't know why but my last commit in my build is from Thu Nov 3 08:47:47 2016 and I can already reproduce the issue.
Comment 6 Commit Notification 2016-11-09 14:15:01 UTC
Tomaž Vajngerl committed a patch related to this issue.
It has been pushed to "master":

tdf#103801 JPEG - don't handle buffer orientation in import

It will be available in 5.3.0.

The patch should be included in the daily builds available at in the next 24-48 hours. More
information about daily builds can be found at:

Affected users are encouraged to test the fix and report feedback.
Comment 7 V Stuart Foote 2016-11-09 15:24:41 UTC
also saw this rotation in OpenGL first manifest at the
32bdc5097013e7efd9c85e1b8df697880e66e925 (2016-11-04_23:30:30) build
which had the RGB color channel issue

But, looks like Tomaž has them both corrected.
Comment 8 Luke 2016-11-10 00:10:24 UTC

I bisected this bug to an 11/4 commit:

If you're seeing this on 11/3, it's a different issue. Please be sure to confirm that Tomaž's patch also fixes your issue. BTW, I tested this on Windows 10 with Nvidia gtx 650 and Intel HD 5000.
Comment 9 V Stuart Foote 2016-11-10 03:53:34 UTC
Its fixed... thanks Tomaž!
