[squeak-dev] Historical help needed: PNGReadWriter class test1

Historical help needed: PNGReadWriter class test1

HI all,

In my code travels I have come across:

'RAA 12/10/2000 10:11 PNGReadWriter class test1 {as
yet unclassified}'

which has become lava code*.

It would probably be good to revive it as a test. I
would like to know what was in the files it
referenced. My curiosity wants to know if they were
some specially tortuous or just ordinary files. ( My
assistant Puck is hoping for tortuous. ;-)

I am also, at Puck's urging, looking for other files
that would be a good test of a png read writer.

the portion of the code that looks at files is here:

d0 := FileDirectory default.
d1 := d0 directoryNamed: 'PngSuite Folder'.
d2 := d0 directoryNamed: 'BIG PNG'.
{d0. d1. d2}.
"keep compiler quiet"
"==
citrus_none_sub.png
citrus_adm7_adap.png
citrus_adm7_aver.png
citrus_adm7_non.png
citrus_adm7_paeth.png
pngs-img-ie5mac.png
=="
fileInfo := {d2. {'citrus_adm7_adap.png'}}.

Yours in service, and curiosity, --Jerome Peace

*lava code is code left over from historical times
which has no use in the current image and yet no one
is willing to take responsiblity for removing it.

Hi -

Have you looked at the PNGReadWriterTests in the GraphicsTests package?
It has some 30+ tests for PNGReadWriter in a variety of situations.

Cheers,
- Andreas

Google did not turn up any of the citrus_* images but the ie5mac can be
found. The PngSuite can also be found, but I think this test method
could be ditched or reworked to be not reliant on arbitrary stuff from
external sources. It was probably useful in development but less so in
deployment.
