I have the same use-case, writing the same image back but removing or altering already existing iTXT chunks. Did you get around using the double decoding @0x6273? Has there been any work on this? If not, would it be (good) enough to just make the fields public inside of StreamingDecoder? I'd be happy to contribute back as I make use of the library myself @HeroicKatora :) |
A getter |
I'm trying to modify an image's
iTXt
metadata. I'm usingStreamingDecoder
to read the chunks from the original image, andWriter::write_chunk
to create a new image with modified metadata. But the API to construct theWriter
needs information such as the image dimensions and color palette, for writing the header.StreamingDecoder
seems to have all this information internally after passing theIHDR
chunk, but it is in a private field with no public getter.My current solution is to read the entire image into memory, and then use
Decoder
, which I can then turn into aReader
and then get the header info fromReader::info()
. But I'm wondering if there is a better way to do this using onlyStreamDecoder
, so I don't have to make two decoding passes?The text was updated successfully, but these errors were encountered:
