[Bug 24278] New: Transparent PNG are shown inverted by applications compiled with Lazarus
http://bugs.winehq.org/show_bug.cgi?id=24278 Summary: Transparent PNG are shown inverted by applications compiled with Lazarus Product: Wine Version: 1.2-rc4 Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs(a)winehq.org ReportedBy: alejandro.lavarello(a)gmail.com Created an attachment (id=30578) --> (http://bugs.winehq.org/attachment.cgi?id=30578) Even at design time, Lazarus shows inverted the PNG in Wine. Applications that are compiled with Lazarus display transparent PNG images upside down. Tested in Wine 1.2 rc4 in Puppy Linux 5 and in WineXO. The same executable shows OK in Windows. A example executable showing the problem can be downloaded from: http://freakshare.net/files/meqi0gmc/ImageMirroredInWine.rar.html duplicated in this other link: http://www.megaupload.com/?d=NVSAW5Y1 According to Marc Weustink, the Lazarus implementer of bitmap handling, this can occur because: " Through the GetObject() function I get the BITMAP info of a given HBITMAP If the HBITMAP was created as DIBsection, the BITMAP.bmBits will point to the data of the bitmap. On "real" windows you are allowed to manipulate this data. For these bmBits I want to know if they are bottom-up or top-down. With the GetDIBits() function I request the first scanline/pixel in bottom-up order (so it is the last line of the bitmap). I cannot compare it to the value I found in bmBits, since top and bottom may have the same pixelvalue. Now I invert the first pixel of bmBits and I request again the first scanline in bottom-up order. If the first pixel did change, then the data was bottom-up. It the pixel didn't change, I was manipulating the top of the bitmap There can be a few issues with wine: 1) bmBits points to a copy of the bitmap data 2) GetDIBits doesn't honor the requested scanline order (== doesn't reorder if bottom-up is requested while the image is top-down) 3) Wine does report a negative height, and I think I request a bottom-up but I get a top-down " (see http://www.lazarus.freepascal.org/index.php/topic,10353.0.html ) -- 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 point is that alpha images in lazarus are not premultiplied, while the AlphaBlend() function requires a premultiplied bitmap. So I need to premultiply all pixels. Therefore I need the pixels of the bitmap. I need the direction of the scanlines in order to get the sourcerectangle of the image we want to alphablend -- 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.

In that example the source bitmap was based on CreateDIBitmap(), which is not the type used for bitmaps in Lazarus. The bitmap_dir_2 example is based on CreateDIBSection(). This shows the lazarus problem.
