问题 My PC crashed and so I had to reinstall all of my libraries; after finishing the install, I realized that some libraries updated to a new version and my code no longer works (due to a new version of openpyxl). I am trying to insert an image into an Excel file, but I do not understand the error messages that are occurring. Other questions seem to be for older versions of openpyxl (for which my original code worked), but do not work for the current version of openpyxl. Your assistance in

问题 If I place (insert-image (create-image "/tmp/test.png")) in a buffer, place the cursor after the last parenthesis and evaluate it with C-x C-e , then the image /tmp/test.png is displayed in the buffer: Pretty neat. But, I had to put the final parenthesis on a separate line, so the image is close to the left-hand side of the buffer. Is there a way to hide the (insert-image ...) text altogether? The text file contains the (insert-image ...) text only, not the image. I'm happy with that, but is

Why Images.Media.insertImage return null

阅读更多关于 Why Images.Media.insertImage return null

I have some code where I run the method MediaStore.Images.Media.insertImage (inserting it from a source not a file name), This code saves the image to the MediaStore and returns the uri of the image.
