问题 I want to use Leptonica library in my iOS app to process images. Does anybody knows how can I create UIImage from the raw data in Leptonica's Pix structure: /*-------------------------------------------------------------------------* * Basic Pix * *-------------------------------------------------------------------------*/ struct Pix { l_uint32 w; /* width in pixels */ l_uint32 h; /* height in pixels */ l_uint32 d; /* depth in bits */ l_uint32 wpl; /* 32-bit words/line */ l_uint32 refcount; /

Convert between OpenCV Mat and Leptonica Pix

问题 I need to convert between OpenCV Mat image and Leptonica Pix image formats in C++. This is being used for binarization of 8bit gray images. 回答1: I found found @ikarliga's answer worked for me because what I needed was to actually convert to the Mat format not necessarily use it with the Tesseract API which is what that OP was asking. Here are both the functions I use. The pix8ToMat function is taken from the node-dv project Pix *mat8ToPix(cv::Mat *mat8) { Pix *pixd = pixCreate(mat8->size()
