Description

Width: 3509
Physical Width Dpi: 300
Physical Width Inch: 1052697.9
Height: 2481
Physical Height Dpi: 300
Physical Height Inch: 744298.5

PngImageParser.java (620):
                 PhysicalWidthInch = (float) ((double) Width
-                        * (double) pngChunkpHYs.PixelsPerUnitXAxis * meters_per_inch);
+                        / ((double) pngChunkpHYs.PixelsPerUnitXAxis * meters_per_inch));
PngImageParser.java (625):
                 PhysicalHeightInch = (float) ((double) Height
-                        * (double) pngChunkpHYs.PixelsPerUnitYAxis * meters_per_inch);
+                        / ((double) pngChunkpHYs.PixelsPerUnitYAxis * meters_per_inch));

After this patch I got correct values:
Width: 3509
Physical Width Dpi: 300
Physical Width Inch: 11.69667
Height: 2481
Physical Height Dpi: 300
Physical Height Inch: 8.2700024
