Hi,

Ive studied many of the demo's and had the idea that Demo29 was the best point to start looking for a good entrypoint to exchange image-data (16bit so not bitmap) using python4delphi. I am using P4D in my project to use a set of opencv procedures on a large set of stored images. The reading of the files is done in python. The result of this calculation is a floatingpoint array that I need to push back to the Pascal side. Thusfar I am doing this by simply saving a 16bit representation of that array in python as a png and then loading that back in Lazarus. This works but has he disadvantage of :
A) write/load the image over IO isnt looking "optimized" for speed
B) the floating point becomes a 16bit image loosing quality.

As stated I studied Demo29 as I had the idea I could overcome disadvantage A. I implemented a stream (as shown in the example) that wrote 16 bit data to python and received 16 bit back using that same stream-approach. This is however a slower than simply writeing/reading a PNG.

So I am searching for a "better" solution but have not seen an example where a 3channel 2D-floating point array gets exchanged between python/pascal.

I am not sure if this is the right place to ask, if not please excuse me !

cheers
