I'm using the latest texsync'd version of ConTeXt on 32bit and 64bit linux. Looks like either ConTeXt or pdfetex can't handle PNG's with an alpha channel.
PNG image data, 8-bit/color RGB, non-interlaced <-- works fine PNG image data, 8-bit/color RGBA, non-interlaced <-- corrupt pdf PNG image data, 8-bit gray+alpha, non-interlaced <-- following error: --- libpng warning: Ignoring bad adaptive filter type libpng warning: Ignoring bad adaptive filter type libpng warning: Ignoring bad adaptive filter type --- repeated ad nauseum
(To benefit anyone coming across this message in the archives:) As a work around, assuming you don't need the alpha, the image can be converted to RGB in The Gimp using Layers > Flatten Image. Alternatively, using Image Magick, the command would be convert image.png png24:image-new.png
i will update the binaries soon, there has been some fixes and extensions to pdftex and there will be a new release Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
