使用Python-Fu / gimpfu,我能够注册一个插件并从Script-Fu控制台运行它。
但是我无法从创建的GUI菜单项运行插件。
无论我从哪个目录下拉菜单中选择哪个条目,我都会收到以下错误:
GIMP版本:2.8.18
插件代码(为简洁起见,省略了一些功能):
import os
from gimpfu import *
# Copy to ~/.gimp-<version>/plug-ins
# Launch GIMP
# Should register a function named python-fu-batch-scale
# Run the function from Filters > Script-Fu > Console
def loadImage(sourceFile):
if isJPEG(sourceFile):
return pdb.file_jpeg_load(sourceFile, sourceFile)
if isPNG(sourceFile):
return pdb.file_png_load(sourceFile, sourceFile)
def saveImage(outputFile, image):
drawable = pdb.gimp_image_get_active_drawable(image)
if isJPEG(outputFile):
saveJPEG(outputFile, image, drawable)
if isPNG(outputFile):
savePNG(outputFile, image, drawable)
def scaleImage(image, maxWidth, maxHeight):
width = pdb.gimp_image_width(image)
height = pdb.gimp_image_height(image)
aspectRatio = width * 1.0 / height
if aspectRatio >= 1.0:
# horizontal
newWidth = min(width, maxWidth)
newHeight = newWidth / aspectRatio
pdb.gimp_image_scale(image, newWidth, newHeight)
else:
# vertical
newHeight = min(height, maxHeight)
newWidth = newHeight * aspectRatio
pdb.gimp_image_scale(image, newWidth, newHeight)
def run(sourceFolder, outputFolder, maxWidth, maxHeight):
if not os.path.exists(outputFolder):
os.makedirs(outputFolder)
filenames = [f for f in os.listdir(sourceFolder) if os.path.isfile(os.path.join(sourceFolder, f))]
for filename in filenames:
sourceFile = os.path.join(sourceFolder, filename)
outputFile = os.path.join(outputFolder, filename)
image = loadImage(sourceFile)
scaleImage(image, maxWidth, maxHeight)
saveImage(outputFile, image)
register(
"batch_scale",

我在Linux上遇到类似的问题,一旦点击目录选择器,插件就会死得很厉害。然而,有一个解决方法:给出一个默认目录(它似乎甚至不需要是有效的目录,至少在Linux版本上):
(PF_DIRNAME, "outputFolder", "Output directory", "/tmp"),
convert
command的一次调用来做同样的事情。<Toolbox>/Xtns/Languages/Python-Fu/
中的菜单注册脚本,你必须查看非常旧的文档。
