Or maybe the standard forces this. I converted the file to psd and saved the image with gimp and photoshop and identify gives exactly the same results: Image: rgb_gimp.png Format: PNG (Portable Network Graphics) Mime type: image/png Class: DirectClass Geometry: 9x9+0+0 Resolution: 37.4x37.4 Print size: 0.240642x0.240642 Units: PixelsPerCentimeter Type: Palette Endianess: Undefined Colorspace: sRGB Depth: 8/1-bit Channel depth: red: 1-bit green: 1-bit blue: 1-bit Channel statistics: Red: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Green: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Blue: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Image statistics: Overall: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Format: PNG (Portable Network Graphics) Mime type: image/png Class: DirectClass Geometry: 9x9+0+0 Resolution: 37.4x37.4 Print size: 0.240642x0.240642 Units: PixelsPerCentimeter Type: Palette Endianess: Undefined Colorspace: sRGB Depth: 8/1-bit Channel depth: red: 1-bit green: 1-bit blue: 1-bit Channel statistics: Red: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Green: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Blue: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Image statistics: Overall: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Colors: 4 Heck, identify gives the same results on the psd file: Image: rgb.psd Format: PSD (Adobe Photoshop bitmap) Class: DirectClass Geometry: 9x9+0+0 Resolution: 95x95 Print size: 0.0947368x0.0947368 Units: PixelsPerInch Type: Palette Endianess: Undefined Colorspace: sRGB Depth: 8/1-bit Channel depth: red: 1-bit green: 1-bit blue: 1-bit Channel statistics: Red: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Green: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Blue: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 Image statistics: Overall: min: 0 (0) max: 255 (1) mean: 103.889 (0.407407) standard deviation: 125.295 (0.491352) kurtosis: -1.85795 skewness: 0.376889 So I'm not sure whether your analysis is correct. Btw, I know freeimage (http://freeimage.sourceforge.net/) only because it's a source of bugs where it's used in deepin's qimageio plugins. Or did you mean a different freeimage? How are you using freeimage with these png's? -- You are receiving this mail because: You are watching all bug changes.
