[Gimp-user] Scripting - How to save JPEG with thumbnails
Hi, I am new to scheme scripting. What i want to do is open pictures from a directory and apply a very simple macro. I can do it manually with the following steps : - open image the_image.jpg. - save as the_image_with_thumbnail.jpg - choose options : q = 0.85 , progressive, and default other options. - check the option : save thumbnail. - Click OK. - close image. Could someone show me some sample scripts to do that ? I've found several way to save a thumbnail in jpg or png format in a separate file, but did not find any script matching the steps i've exposed ... Thanks for any reply G.B. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Hi Sufyan, Am 07.05.2007 um 06:19 schrieb sufyan bakir: I am using Gimp on Mac OSX 10.4.9. I have a Wacom tablet connected to my PC but cannot seem to have the pressure sensitivity working. In the File Preferences Input Devices it did not detect the connected Wacom tablet. Although this is not the right mailing list (gimp-user would be a better place) I can answer your question. Unfortuntely the pressure sensitivity is not going to work in GIMP at OS X right now. I know this does not help you (us) right now, but it's not GIMPs fault, but a missing function in Apples X11 application. Good news is, that there might be a native gtk (which is the GIMPs toolkit) in the future, which replaces X11 for GIMP at OS X. Greetings, lexA How to activate this function? Please help.

Using a bash script or DOS batch file with imagemagick is a better and easier solution. Below is a bash script that I use to create thumbnails of photos from my digital camera. You can pass the jpg quality parameter to convert - I used the default which is 75% I think. The options are in the docs. - #!/bin/bash echo Converting ... if [ ! -d resized-1024x768 ] then mkdir resized-1024x768 fi if [ ! -d resized-256x192 ] then mkdir resized-256x192 fi # Loop through all jpg files in current folder # for i in *.jpg do FileName_Stripped=`echo $i | cut -d. -f1` if [ ! -e resized-1024x768/$FileName_Stripped-1024x768.jpg ] then echo Converting $i to $FileName_Stripped-1024x768.jpg convert -resize 1024x768 $i resized-1024x768/$FileName_Stripped-1024x768.jpg fi if [ ! -e resized-256x192/$FileName_Stripped-256x192.jpg ] then echo Converting $i to $FileName_Stripped-256x192.jpg convert -resize 256x192 $i resized-256x192/$FileName_Stripped-256x192.jpg fi done echo Done - Thank you very much for pointing this tool to me. However ... I can't find in imagemagick the ability to save thumbnail as EXIF data in the jpeg, and not in a different picture. Ok, so if someone want to write Exif thumbnail to jpeg i've done this with imagemagik and exiftools to write thumbnail generated by imagemagik... Maybe there's a better way to do this but this tools works just as expected and there's no loss of other exif info. But if someone ever got a scheme script to do that through GIMP ... i'am interested Thanks list ! ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

It's acutally a bad idea to do that. When you are opening a JPEG file and saving it again as JPEG, you are recompressing it and this recompression means a loss of quality. This can be avoided by using a tool that manipulates the JPEG file without recompressing the image data. Such tools are available and they can even rotate the image for you without decompressing the image data. See for example exiv2 (http://www.exiv2.org/). The manual page says that it can insert thumbnails. Sven ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

[Gimp-user] hi, merge two jpg together, the 2nd one does not display
Dear All I just installed the GIMP on my windows box. My task is simple, merging two jpg files together. When I increase the canvas size and copy and paste the second jpg into the first one, there is only a dashed outline of the second picture. I have no idea what's wrong. Could anyone help me? Thanks.
