Subject: Fixed copying only 1/3 of scanline when saving TIFF image in rare cases.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/a000de7794cb20bdd772e76dda87baa27642056b?ds=sidebyside

Fixed copying only 1/3 of scanline when saving TIFF image in rare cases.

If our calculated image pitch is not equal to what TIFFScanlineSize returns a scanline buffer would be used. In that case the number of bytes being copied was equal to the image's width instead of pitch (width times 3).
