In Squeak, if I have the data for a PNG image, how can I put it into an ImageFrameMorph?

Using:

Code:

t7 _ (HTTPSocket httpGet: 'http://' , msServer , '/getavatar/' , t1) contents.
    t8 _ ImageFrameMorph new initFromForm: t7.

does not seem to work.

I assume it has something to do with PNGReadWriter.

PNGReadWriter createAFormFrom: t7

assuming you're talking about a PNG... now I forgot what we used.

I'm now trying this:

Code:

t7 _ (HTTPSocket httpGet: 'http://' , msServer , '/getavatar/' , t1) contents.
    scratchFrame write: t7 toFile: 'test.png'.
    t8 _ (FileStream readOnlyFileNamed: 'test.png') binary.
    t9 _ ImageReadWriter formFromStream: t8.
    t8 close.
    t10 _ ImageFrameMorph new initFromForm: t9.
    body addMorph: t10.

but it still doesn't work.

Trying

Code:

t7 _ (HTTPSocket httpGet: 'http://' , msServer , '/getavatar/' , t1) contents.
    scratchFrame write: t7 toFile: 'test.png'.
    t8 _ PNGReadWriter createAFormFrom: 'test.png'.
    t9 _ ImageFrameMorph new initFromForm: t8.

doesn't work either. It says that t8 is of type PNGReadWriter, not of the form type.

it's right. Take the first value of t8 (t8 first) to get the image.

Also, I don't see why you're writing to a file! createAFormFrom wants a stream (which is actually precisely t7), not a string! The latter will give you a pretty bad image.

…and then stop calling your temporary variables tn.

Squeak automatically does that. I can't do anything about it.

Squeak automatically does that when you're missing a .changes file, because it has nowhere to put the method sources.

So if I make a .changes file, it won't automatically do that? I'll try that.
