Click Image at the top of the image toolbar. Use the rectangle marquee to select what portion of the image you want to crop. Supporting other angles, colors etc is trivial to add. Click Image Click Rotate Canvas Select 180, 90 CW, 90 CCW, or Arbitrary to manually specify your angle. # Copy the relevant area from the source image

def draw_text_90_into (text: str, into, at):įont = uetype (r'C:\Windows\Fonts\Arial.ttf', 16) This means that we draw onto the final surface immediately, without having to resort to masks. Here is a version that instead crops the area of the source image that will be drawn onto, rotates it, draws into that, and rotates it back. The previous answers draw into a new image, rotate it, and draw it back into the source image. Here it is in a colab you should provide an example image to the colab. Image.paste(watermark, (px, py, px + wx, py + wy), watermark) Watermark = watermark.rotate(angle, expand=1) Watermark = Image.new('RGBA', (mark_width, mark_height), (0, 0, 0, 0))ĭraw.text((0, 0), text=text_to_be_rotated, font=font, fill=(0, 0, 0, opacity))Īngle = grees(math.atan(pdf_height/pdf_width)) Mark_width, mark_height = font.getsize(text_to_be_rotated) #font = ImageFont.load_default() # fallback # load font (tweak ratio based on your particular font)ĭiagonal_length = int(math.sqrt((pdf_width**2) + (pdf_height**2)))ĭiagonal_to_use = diagonal_length * DIAGONAL_PERCENTAGEįont_size = int(diagonal_to_use / (message_length / FONT_RATIO))įont = uetype(r'./venv/lib/python3.7/site-packages/reportlab/fonts/Vera.ttf', font_size) Text_to_be_rotated = 'Harry Moreno = len(text_to_be_rotated)

from PIL import Image, ImageFont, ImageDraw Handles arbitrary image ratios, sizes and text lengths by calculating the angle of the diagonal and font size. Here's a fuller example of watermarking diagonally.
