What happend to the writeImgPgm function?

[lidija]

Hi,

I would like to write pgm image file with OptiML. The documentation says that there is a function named writeImagePgm. However, I found MLOutputWriter.writeImgPgm in the older version of Delite. The new one does not contain such a function, or at least I cannot find it. Could you, please, clarify is there any alternative?

Thanks,
Lidija

Hi Lidija,

It looks like the writeImagePgm function was not ported to the new version of OptiML, as you noted. If you'd like you can submit a Github issue for an improvement and we'll try to add it in the short-term. You should also be able to accomplish the same thing (or something very close) using the basic writeMatrix functionality with a pre-constructed matrix containing PGM values. The only thing is you'll need to manually add the PGM header after-the-fact. Or you could use writeVector with a DenseVector[DenseVector[String]], where each inner vector represents a single row of the PGM file, including header.

Hope that helps,

Arvind

Thank you very much for the quick response. That explains everything, I will go with the idea of vector of vectors, I like that.

Thank you again,
