1-bit RGB assumed in colorConvertTest, wrong in getPixelColorRGBA8 about lodepng HOT 1 CLOSED

You're correct, 1-bit RGB does not exist in PNG and is not supported by lodepng either since it only supports the valid PNG color type / bit depth combinations.

In the unit test, the 1 there was a typo, it actually had to be 8, and the test passed by coincidence instead (since it was treating it as 16 bit in the else case and the bit pattern must have matched something valid by coincidence)

Extra error handling in the lodepng_convert and lodepng_get_raw_size functions would be redundant, the error checking for valid color type / bit depth combination already happens elsewhere in the main decoding and encoding flow

Thanks for reporting! I fixed the test to use 8, and 16, instead of the wrong 1 bits.
