嗨,为ex绘制三个不同的文本和不同的选项:
文本必须换行。
def pil_image(request):
text = request.GET.get('text', None)
font = str(request.GET.get('font', 'arial'))
fontsize = int(request.GET.get('fontsize', '20'))
textcolor = str(request.GET.get('textcolor', '000'))
import Image, ImageDraw, ImageFont, textwrap
img = Image.open('media/text/transparent.png')
img = img.convert("RGBA")
datas = img.getdata()
w, h = img.size
newData = []
for item in datas:
if item[0] == 255 and item[1] == 255 and item[2] == 255:
newData.append((255, 255, 255, 0))
else:
newData.append(item)
img.putdata(newData)
draw = ImageDraw.Draw(img)
font = ImageFont.truetype("media/text/fonts/" + font + ".ttf", fontsize, encoding="unic")
margin = offset = 40
for line in textwrap.wrap(text, width=48):
w, h = draw.textsize(line)
draw.text((margin, offset), line, font=font, fill='#'+textcolor)
offset += font.getsize(line)[1]
del draw
img.save("media/text/custom.png", "PNG")
return HttpResponse("<img src='/media/text/custom.png'>");
在使用RGBA colormode时,“fill”参数应该是一个有4个数字的元组。
对于不透明红色:
就这么做
