I tried the commands:
imshow(originalImage);
imsave;
it works, but I want the matlab to automatically save the image in bmp format (in the current folder).
I tried to use:
save('myimage.bmp','originalImage');
the picture was saved, but on the image itself, instead of the picture, I saw this message:
"windows photo viewer can't open this picture because the file apears to be damaged, corrupted, or is too large".
(the size of the picture is 5kb).
Thanks!
Use the function imwrite to do that:
imwrite(image_matrix, 'myimage.bmp', 'bmp')

I am trying to have TYPO3 10.4.12 generate webp images as described in the example on this page: https://docs.typo3.org/c/typo3/cms-core/master/en-us/Changelog/10.3/Feature-90416-SpecificTargetFileExtensionInImage-relatedViewHelpers.html
{f:uri.image(image:images.0, fileExtension: 'webp')}
I am using GraphicsMagick and with gm version I get
WebP yes
and converting a picture to webp manually via command line works.
Also cwebp is installed.
If I try fileExtension: 'png' it generates a png file so the parameter seems to work.
However the image does not get converted, instead the original unprocessed image gets referenced.
The main problem seems to have been that I needed to add webp to the [GFX][imagefile_ext] configuration.
Additionally sometimes it only worked after removing all generated images under Remove Temporary Assets in the Maintenance section.
Yes that is true, webp must be added to image file list. In addition we faced another problem with webp. If you create an image as jpg with a width and after that the same image as webp also in the same width, only the jpg was generated. That's why we added 1px to the jpg images.
Now nearly all picutures are delivered in a modern way on https://www.in2code.de
TinyMCE 4: I have implemented the image file/upload from local source, using php to save the uploaded file into a directory, with tinyMCE referencing this image. Works fine. This leaves a simple html text file to save in the database.
However, I see that the user can just cut and paste an image directly into the textbox, resulting in the image showing up and becoming a base64 image string, which defeats the purpose of storing only html text. Now the text could become extremely long if this base64 image is not prevented.
Is there a way to prevent this image paste action in tinyMCE? Or better yet, a way to automatically convert this paste into an image file and have it stored in the same place as the other images on the fly?
I know I could convert base64 images to a jpg files and store after submitting the form to a php handler, but would seek a simpler answer if possible.
The documentation is your friend for this issue. TinyMCE can certainly help you convert the images on the fly as they are pasted into the editor:
https://www.tinymce.com/docs/advanced/handle-async-image-uploads/
You can also stop the images from appearing in the first place if that is your preference:
https://www.tinymce.com/docs/plugins/paste/#paste_data_images
I have added a ImagePlugin as described in https://www.tinymce.com/docs/plugins/imagetools/#sdkinstallation.
I can modify a photo in an editor but I don't know how to save it after modifications.
After posting a form with wysiwyg I get :
Cannot convert
blob:http://10.48.200.155/5e32b981-6e33-48cc-87b1-512abd653912 to
Blob. Resource might not exist or is inaccessible.
When you use the image editing tools to modify an image the editor creates a Base64 encoded new image. This exists (right after the editing) only in the browser. To permanently save the image to something other than Base64 you need to follow these instructions:
https://www.tinymce.com/docs/advanced/handle-async-image-uploads/
The net is that the editor can be configured to send the image binary to a script of your choice. That script needs to save the image somewhere appropriate and return JSON with the path to the new image's location.
I have rtf document in which is picture as the background. Problem is taht the file is 138MB and can't work with Oracle BI Publisherom Desktop. That software work with smaler - normal size of pictutures. My main problem is how to get picture from rtf file and than I can to resize it in something like acdsee. It apeears unposible to get that picture from the file. Printscrean is not an option.\
Thanks.
I successed to take picture from watermark. Just double click in the upper part of screen where is the header and chose save as.
I can't figure out why I can't load a local png file into my ipython notebook. I have in a cell:
from IPython.display import Image
i = Image('../heavy_vortex_3/frames/x_snap_n0000000.png')
i
and instead of seeing the image, i get a little "broken picture" image. Remote pngs work fine, for example:
Image(url='http://upload.wikimedia.org/wikipedia/en/b/bf/Firefox.png')
happily renders that little fox guy. Is there something I'm doing wrong?
Image assume by default you are passing an url and will display an img tag with the href attribute set to the value you passed. You are basically trying to access
http://localhost:8888/../heavy_vortex_3/frames/x_snap_n0000000.png
And probably unless you use some kind of middleware, your asking that to the ipython webserver that have no clue of what you wish.
I think what you want is to display an image with respect to the current working directory of the kernel. So you want to use the filename ( If I remember correctly) kwarg.:
Image(filename='../heavy_vortex_3/frames/x_snap_n0000000.png')
Which will actually read the file, and send it on the wire.
