Can you give me a sample image? Same image, one version with, the other without interlacing. Attach it if it is a small one, or you can send it to my mail address, file size is then no problem. Created attachment 21741 [details]
Sample image - noninterlaced PNG
This is a non-interlaced PNG file, displayed correctly by the image editor
Created attachment 21742 [details] Sample image - interlaced PNG This is the same image as attachment 21741 [details], but saved as an interlaced PNG file. Both were created using the GIMP by taking a screenshot of the KDE bug tracking system's homepage and saving as PNG with interlacing turned either on or off. Note, that for both images, the thumbnail in the main digikam window is displayed correctly, only the image editor has problems with interlaced PNGs. Confirming problem for Showfoto 0.7svn I see thumbnail in thumbbar but get message "Cannot load file int.png" This is console output: Found dcraw version: 8.77 QMultiInputContext::changeInputMethod(): index=0, slave=xim QMultiInputContext::changeInputMethod(): index=0, slave=xim QFile::open: No file name specified QFile::open: No file name specified libpng warning: Ignoring bad adaptive filter type libpng warning: Extra compressed data. libpng warning: Extra compression data libpng error: incorrect header check showfoto: WARNING: Failed to load image int.png showfoto: WARNING: [Digikam::DImg* Digikam::DImgInterface::getImg()] d->image is NULL Debugging another problem I noted a problem in the PNG loader that may be causing this (doc says that png_set_interlace_handling shall be called before png_read_update_info). I will look into that later. Mik, What's news about this file ? It still valid using digiKam 0.9.5 or 0.10.0 ?
