软件功能基于mupdf,UI使用wxpython开发
功能:
支持pdf转图片,图片格式png
支持批量转换
使用:
第一步,点击按钮添加文档到列表,或直接将待转换文档拖入列表
第二步,选择输出目录
第三部,点击转换
核心代码:
class Debug(object):
DEBUG = True def TraceLog(self, log=None):
if Debug:
import traceback
traceback.print_exc()
if log:
print(log) class PDF2IMGProcess(Debug):
def __init__(self, path, callback=None):
try:
self.pdf_doc = fitz.open(path)
self.file_name = os.path.basename(path)
self.pages = self.pdf_doc.pageCount
self.callback = callback
self._Running = True
except:
self.TraceLog() def _TransFile(self, output_path):
if self.callback:
self.callback({'file': self.file_name, 'status': '开始!'})
if self.pages > 0:
output_path = os.path.join(output_path, self.file_name)
os.makedirs(output_path, exist_ok=True)
for p in range(self.pages):
if not self._Running:
break
if self._TransPage(output_path, p):
if self.callback:

page = self.pdf_doc.loadPage(page_no)
matrix = fitz.Matrix(scale, scale)
try:

pix.writePNG(output_name)
return True
except:

return False def Start(self, output_path):
