Re: Best way to base64encode a jpeg file ?
Richard & Mark,
Thank you both for your suggestions.
I actually made some progress, as there were 2 different issues :
1- the syntax of the multimodal json curl must be
{"type" : "image_url", "image_url" : {"url":
"data:image/jpeg;base64,{_BASE64_}"}}
instead of
{"type" : "image_url", "image_url" : {"url": "data:image/jpeg;base64
{_BASE64_}"}}
I found the tip in an obscure blog post from early 2023.
Even the latest ChatGPT-4o3 missed the point.
2- I still have a problem with the base64 encoding of a jpeg file in LC.
Long story short, I am trying to send a curl request to a vision AI
model running with
LM studio. I tried several models that didn't give much details in the
error messages,
except for "bad request" or "data must be base64 encoded jpeg".
But the last one I tried returned :
{"error":"Input buffer has corrupt header: VipsJpeg: Corrupt JPEG data:
13 extraneous bytes before marker 0x8e\nVipsJpeg: Unsupported marker
type 0x8e"}
Here is my code for base64 encoding :
put URL ("file:" & "myfile.jpg") into timagedata
put base64encode(timagedata) into tBase64Image
replace return with "" in tBase64Image
Thanks,
jbv

Use `binfile:` here instead of `file:` so the engine doesn’t treat the data as
native text and fiddle with it

You need url safe base64 encoding so you need:
local tEncoded
put base64Encode(pData) into tEncoded
replace return with empty in tEncoded
replace "+" with "-" in tEncoded
replace "/" with "_" in tEncoded
replace "=" with empty in tEncoded

Re: Best way to base64encode a jpeg file ?
I’m curious whether or not this solution worked…

RE: Best way to base64encode a jpeg file ?
I can see getting rid of extraneous CRs or LFs but aren’t "+","/" and "=" part
of the encoding and corrupt the base 64 data stream? Or am I missing something?

You need url safe base64 encoding so you need:
local tEncoded
put base64Encode(pData) into tEncoded
replace return with empty in tEncoded
replace "+" with "-" in tEncoded
replace "/" with "_" in tEncoded
replace "=" with empty in tEncoded
