Meanwhile I found some PHP functions to crop the image and change the contrast and brightness. The code is as follows:
// Resize $thumb = imagecrop($source, ['x' => 830, 'y' => 330, 'width' => 115, 'height' => 30]); // Filter imagefilter($thumb, IMG_FILTER_GRAYSCALE); imagefilter($thumb, IMG_FILTER_BRIGHTNESS, +50); imagefilter($thumb, IMG_FILTER_CONTRAST, -50); As a result I got at least a result: 39984 Its still not correct, but better than no identification of any letter... How can I improve? Martina Ilgon schrieb am Montag, 25.
