Memory usage increase #24

Closed toine512 closed 1 month ago

Hi Mr Bank,

I'm using PNGdec in my ESP-IDF project (ESP32-S3) with direct callback rendering. With latest master code (a0f4b16) I noticed an increase of about 1.5 KiB in static memory consumption compared to commit 8abf6be (31 jan 2022). Is that to be expected?

Thanks.

You can see why in the commit you referenced. I increased the line buffer to allow decoding of up to 480-wide 32-bit pixels. You're welcome to change your local copy to buffer fewer pixels if you're working with small images.
