Zuzbala Posted June 1, 2023 Posted June 1, 2023 Hi, I'm new to Affinity Designer (installed trial version today) and I'm going mad with this : - I create a document with settings : RGB32 / Transparent background checked - Draw a shape, or copy paste a bitmap from Apple Preview - File/Export, I can see the transparent checkerboard and "matte" box contains a red line, so seems good - Do the export, reopen the PNG file with Apple Preview and have a look to the "Inspector" Depth is 16 bits. I verified with the "identify" command line and got : test1.png PNG 320x176 320x176+0+0 16-bit sRGB 6589B 0.000u 0:00.000 I did several trials and absolutely can't export as a PNG32 What am I missing ??? test1.afdesign Quote
walt.farrell Posted June 1, 2023 Posted June 1, 2023 Welcome to the Serif Affinity forums. The PNG format does not support the RGB/32 color format; only RGB/8 and RGB/16 for color, and Gray/8 and Gray/16 for grayscale.
