1. Why do you use PSM_SINGLE_BLOCK_VERT_TEXT for single character? 2. If I got it right - if you use command line you read image data from disk, when you use API you read image data from memory (cv?). Try to avoid using different sources (e.g. read image from disk in case of API to avoid mistakes in reading from memory...)
