问题描述
import os
import glob
from PIL import Image
files = glob.glob('/Users/mac/PycharmProjects/crop001/1/*.jpg')
for f in files:
img = Image.open(f)
img_resize = img.resize((int(img.width / 2),int(img.height / 2)))
title,ext = os.path.splitext(f)
img_resize.save(title + '_half' + ext)
我想将新图片保存到
"/Users/mac/PycharmProjects/crop001/1/11/*.jpg"
不是
"/Users/mac/PycharmProjects/crop001/1/*.jpg"
任何帮助将不胜感激！
解决方法
您可以通过更改此处的 //! A dummy XError handler which just skips errors
static int xErrorDummyHandler (Display*,XErrorEvent* ) { return 0; }
...
Window aWindow = ...;
Display* aDisp = ...;
GLXFBConfig anFBConfig = ...;
bool toDebugContext = false;
GLXContext aGContext = NULL
const char* aGlxExts = glXQueryExtensionsString (aDisp,aVisInfo.screen);
if (!checkGlExtension (aGlxExts,"GLX_ARB_create_context_profile"))
{
std::cerr << "GLX_ARB_create_context_profile is NOT supported\n";
return;
}
// Replace default XError handler to ignore errors.
// Warning - this is global for all threads!
typedef int (*xerrorhandler_t)(Display*,XErrorEvent* );
xerrorhandler_t anOldHandler = XSetErrorHandler(xErrorDummyHandler);
typedef GLXContext (*glXCreateContextAttribsARB_t)(Display* dpy,GLXFBConfig config,GLXContext share_context,Bool direct,const int* attrib_list);
glXCreateContextAttribsARB_t aCreateCtxProc = (glXCreateContextAttribsARB_t )glXGetProcAddress((const GLubyte* )"glXCreateContextAttribsARB");
int aCoreCtxAttribs[] =
{
GLX_CONTEXT_MAJOR_VERSION_ARB,3,GLX_CONTEXT_MINOR_VERSION_ARB,2,GLX_CONTEXT_PROFILE_MASK_ARB,GLX_CONTEXT_CORE_PROFILE_BIT_ARB,GLX_CONTEXT_FLAGS_ARB,toDebugContext ? GLX_CONTEXT_DEBUG_BIT_ARB : 0,0
};
// try to create a Core Profile of highest OpenGL version (up to 4.6)
for (int aLowVer4 = 6; aLowVer4 >= 0 && aGContext == NULL; --aLowVer4)
{
aCoreCtxAttribs[1] = 4;
aCoreCtxAttribs[3] = aLowVer4;
aGContext = aCreateCtxProc (aDisp,anFBConfig,NULL,True,aCoreCtxAttribs);
}
for (int aLowVer3 = 3; aLowVer3 >= 2 && aGContext == NULL; --aLowVer3)
{
aCoreCtxAttribs[1] = 3;
aCoreCtxAttribs[3] = aLowVer3;
aGContext = aCreateCtxProc (aDisp,aCoreCtxAttribs);
}
bool isCoreProfile = aGContext != NULL;
if (!isCoreProfile)
{
std::cerr << "glXCreateContextAttribsARB() failed to create Core Profile\n";
}
// try to create Compatible Profile
if (aGContext == NULL)
{
int aCtxAttribs[] =
{
GLX_CONTEXT_FLAGS_ARB,0
};
aGContext = aCreateCtxProc (aDisp,aCtxAttribs);
}
XSetErrorHandler (anOldHandler);
// fallback to glXCreateContext() as last resort
if (aGContext == NULL)
{
aGContext = glXCreateContext (aDisp,aVis.get(),GL_TRUE);
if (aGContext == NULL) { std::cerr << "glXCreateContext() failed\n"; }
}
参数将处理后的图像保存到您的首选目录 (/Users/mac/PycharmProjects/crop001/1/11/*.jpg)。
假设您仍想保存文件名中带有 img_resize.save() 后缀的处理过的图像。所以最后的代码在这里：
