--- Comment #11 from ape <[email protected]> --- Created attachment 76801 --> https://bugs.freedesktop.org/attachment.cgi?id=76801&action=edit filter's work (AOO-3.4.1 vs. LO-4.0.3) Michael, Apache OpenOffice-3.4.1 uses a bilinear filter to output each additional PNG image. This is a quick filter of low quality. Therefore: - Apache Draw opens the file with the time that is acceptable to the user; - no messages in The Apache Bugzilla. LibreOffice-4.x.x uses the Lanczos filter to output each additional image: “Release Notes 3.6 > Core: … Added Lanczos algorithm for resizing of images and use it instead of interpolate algorithm. This change has increased the quality of images when reducing image resolution in PDF export. fdo#46378 (Tomaž Vajngerl)” This filter determines the transparency of the color at each point of each additional PNG image. Therefore, the filter works slowly, but with high quality. I found the bug because of this. You can compare works of filters if you look the picture in the attachment. In the image: at the top - Apache bilinear filter; at the bottom – the Lanczos filter (LibreOffice_4.x.x). I think that we have needs for return to LibreOffice-3.6.5. -- You are receiving this mail because: You are the assignee for the bug.
