... (and IOParams.DpiY) with ReadPNGStream in 10.0.1
It was correct in 9.2 but in 10.0.1 it delivers 99 dpi instead of the correct 100 DPI.
Tinkering with the code I saw in pngfilt.pas that in 10.0.1 the png params were read with IEWicRead(...) as default -> {ifdef INCLUDEWIC} whereas in 9.2 the native code below was executed with the correct result.
Reverting that resolved my problem so far - but please include a fix for the next version.
I tried to attach some example files - that was not possible; email me for examples if needed. |

Hi Harry
Yes, we've fixed this rounding error for 10.0.2.

It's a 64bit App and by changing comfortable to
IEGlobalSettings().PNGEngine := ieenDLL;
and using the dll:
->IO.paramsfromfile delivers the correct FDPIX of 100dpi.
I'm happy with that.
The Point still stands: with IEGlobalSettings().PNGEngine:= ieenWIC;
->IO.paramsfromfile delivers the wrong value DPIX and DPIY of 99dpi. - please fix for next version. Thanks!

Hi
Is this a 32bit or 64bit app?
Please check your PNG engine:
https://www.imageen.com/help/TIEImageEnGlobalSettings.ActivePNGEngine.html
If you are using WIC, then it is now used to DPI information. If this is a 64bit app, you should add ielib64.dll to your EXE folder.
