Hi,
I follow the official instruction
I use the official Hello world example provided in the wiki
I save the hello world diagram in both PNG and SVG formats:
HelloWorld.png
HelloWorld.svg
both files open successfully and show the same diagram as a picture.
Now, let's do the reverse process convert image to code.
test 1: PNG
java -jar plantuml.jar -metadata HelloWorld.png > HelloWorld_png.puml
the output is correct, I see the code in file HelloWorld_png.puml:
------------------------
HelloWorld.png
@startuml
start
:Hello world;
stop
@enduml
PlantUML version 1.2025.3beta5(Unknown compile time)
(GPL source distribution)
Java Runtime: OpenJDK Runtime Environment
JVM: OpenJDK 64-Bit Server VM
Default Encoding: UTF-8
Language: en
Country: US
------------------------
test 2: SVG
java -jar plantuml.jar -metadata HelloWorld.svg > HelloWorld_svg.puml
The output is wrong, I see the code in file HelloWorld_svg.puml:
------------------------
HelloWorld.svg
------------------------
However, I see the PUML code in the command line:
C:\testPUML>java -jar plantuml.jar -metadata HelloWorld.svg > HelloWorld_svg.puml@startuml
start
:Hello world;
stop
@enduml
C:\testPUML>
strangely, the command line doesn't show the code when the input file is PNG.
This is very inconvenient.
I know the old version of plantUML.jar (4 years ago) works but I don't have it anymore. Is it possible to download the 4-year old file from somewhere safe?
I can share my 2 image files if that helps.
Of have I misread the user guide?
