Thanks for your reply.
I'm using ImgeMagick of my own building on macOS 10.13.6.
I'll look closer at this issue.

Thanks.
I looked into delegates.xml.
<delegate decode="pnm" encode="trace" command="&quot;potrace&quot; --svg --output &quot;%o&quot; &quot;%i&quot;"/> part only exists in ImageMagick 7.0.8-65.
And that part seemed to be added in ImageMagick 7.0.8-62.
So I tried ImageMagick 7.0.8-61 and I get the ...

For reference:

1. I install potrace-1.16.mac-x86_64 from Potrace and run:
convert logo.png logo.svg

2. ImageMagick 7.0.8-65 converts PNG to SVG( monochrome vectorized ) image.

3. ImageMagick 7.0.7-39 converts PNG to SVG( embedded data:image/png ...

Thanks for your help.
I tried mageMagick 7.0.8-65.
But this time conversion failed end up with:
---
convert: delegate failed `'potrace' --svg --output '%o' '%i'' @ error/delegate.c/InvokeDelegate/1867.

For now, I use ImageMagick 7.0.7-39 to convert PNG to SVG.

I don't expect that ImageMagick converts raster image to vectorized image.
Without Inkscape, ImageMagick 7.0.7-39 can convert a PNG file to a SVG(embedded data:image/png;base64) file.
But ImageMagick 7.0.8-64 fails.

Sorry my mistake.

Converting PNG to SVG fails with ImageMagick 7.0.8-64 on MacOS version 10.13.6.

I tried converting a PNG to a SCG image but fails getting an error as below:
---
Assertion failed: (image->blob->type != UndefinedStream), function WriteBlobStream, file MagickCore/blob.c, line 1554.
Abort trap: 6

I tested with ImageMagick 7.0.7-39 and PNG to SVG conversion sucseeds.

Just a quick note:

I tried to build the latest ImageMagick-master (470655aa95fb3178ecca6b545f5e6a1654f0da85) with "MKDIR_P="/bin/mkdir -p" --disable-dependency-tracking".
The isuue seems to be fixed tentatively.

Thanks a lot.

Case 1.
I configured:
--------------
export PKG_CONFIG_PATH="/usr/local/libpng/lib/pkgconfig/:/usr/local/zlib/lib/pkgconfig/"
./configure --prefix=/usr/local/magick --with-png

and configure fails:
--------------

I can solve the problem.

1) I installed zlib-1.2.11 into /usr/local/zlib.

2) Add configuration option:
export PKG_CONFIG_PATH="/usr/local/libpng2/lib/pkgconfig/:/usr/local/zlib/lib/pkgconfig/"
3) Using libpng-1.6.32, I can compile ending up with "PNG --with-png=yes yes" and succeed to build with ...

I can't answer the question, but I suggest you read the config.log that IM made for more details about why "--with-png" failed.


Thanks.

This is from config.log
