Leptonica не может выровнять текст, повернутый на 45 и 135 градусов. ⇐ C++

[Гость]

I'm having an issue working with Leptonica version 1.80.0 on a Red Hat 9 machine. I'm using the function

Код: Выделить всё

pixDeskewGeneral(...)

to deskew some images before being processed by Tesseract for OCR text extraction.

This function works great with images rotated 5º, 10º, 15º..., and 40º clockwise; the angle is detected correctly, and the image is deskewed.

But when text is rotated 45º or 135º,

Код: Выделить всё

pixDeskewGeneral(...)

does not detect the correct angle, and the image is not deskewed.

Here you have an example that reproduces the issue:

Код: Выделить всё

/// \file deskew.cpp /// Image deskewing utility /// /// Build it by running: ///     g++ -o deskew deskew.cpp -llept #include  #include  #include  /// Get image format based on file extension l_int32 getFormatFromExtension(const char* filename) {     const char* extension = strrchr(filename, '.');     if (extension) {         if (strcmp(extension, ".png") == 0)             return IFF_PNG;         else if (strcmp(extension, ".jpg") == 0 || strcmp(extension, ".jpeg") == 0)             return IFF_JFIF_JPEG;         // Add support for other image formats as needed     }     // Default to PNG format if extension not recognized     return IFF_PNG; } /// Main entry point int main(int argc, char* argv[]) {     if (argc != 3) {         std::cerr
