Set Image output from extension

[Patryk_F]

Yes. Use the latest source. Helper blocks is a fairly new feature.

[jean-marc_Latour]

with new AI version, i have a compil error !:

error: Property EditImage.Image has no category.

@DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void Image(String filePath) {
		Bitmap bitmap=DefineImage(filePath);
		this.globalBitmapSet=true;
	}

(without compil error with old version...)

[Patryk_F]

Show the entire error and the current code. In errors, it shows the number of the java code line in which the error occurs.

Aaah, yes. In the new version of aap inventor, you must assign a category to each property. You need to determine whether the property affects appearance or behavior.

@jean-marc_Latour

@DesignerProperty()

in DesignerProperty, you need to specify the editortype?

like

@DesignerProperty(editorType = PropertyTypeConstants.PROPERTY_TYPE_STRING, defaultValue = "xxxxx")

[Patryk_F]

No, it's not about the editor type, but about the property categories.

I don't remember exactly, and I have no way to check now. Something like: propertyCategory = behavior

[jean-marc_Latour]

@Kevinkun

in DesignerProperty, you need to specify the editortype?

@DesignerProperty(editorType = PropertyTypeConstants.PROPERTY_TYPE_STRING,defaultValue = "no Image")
    @SimpleProperty(description = "Sets the Image ")
    public void Image(String filePath) {
		Bitmap bitmap=DefineImage(filePath);
		this.globalBitmapSet=true;
	}

same compil error

[Patryk_F]

Open the java source of any component and find something similar to what I wrote above

[Kevinkun]

@jean-marc_Latour

@SimpleProperty(description = "Sets the Image ")

@SimpleProperty(category = PropertyCategory.BEHAVIOR, description = "Sets the Image ")

[jean-marc_Latour]

@Kevinkun

@SimpleProperty(category = PropertyCategory.BEHAVIOR, description = "Sets the Image ")

That's it !

but new version doesn't solve my problem:
@Asset({".png", ".jpeg", ".jpg"}) have compil error...

@DesignerProperty()
    @SimpleProperty(category = PropertyCategory.BEHAVIOR, description = "Sets the Image ")
    public void Image(@Asset({".png", ".jpeg", ".jpg"}) String filePath) {
		Bitmap bitmap=DefineImage(filePath);
		this.globalBitmapSet=true;
	}

@Patryk_F

import com.google.appinventor.components.annotations.Asset;

Oh no ! sorry ! i forgot ```
import com.google.appinventor.components.annotations.Asset;

so it works...thanks

[Kevinkun]

where are you writing your code? Why need to import package manually?
normally the IDE will do this work.

[jean-marc_Latour]

I use Visual Studio Code to write my code and use Git to compil it.

as explain here

How to extension dev

what guide you can get in this post? in this post you will understand how to make extension from start to end step by step clearly step 1: download note pad++ it won't be in your PC usually download form needed to edit code step 2: download git bash (mingw) it is for cloning,java to aix compiling step 3: download: Ant 1.10.1 (Binary Distributions)-( apache-ant-1.10.1-bin.zip) this is old version but required version like this [i.JPG] (scroll down to find this) step 4: download…

is there a easier way ?

[jean-marc_Latour]

I updated my first post.
correcting some small bugs.
and take into account all posts

[Taifun]

This thread up to now was about fixing the bugs in your extension
Now it looks like you are close to publish it
Please start a new thread in category Extensions to present your app considering

##PLEASE READ FIRST## Posting a new extension to the community

Submission of new extensions The community has adopted a new approach to the posting of extensions on the community, and all new extensions are now put through an evaluation process. We do recognise that you have put a lot of time and effort into creating your extension. We want you to be able to present your extension in the best condition possible, as bug free as possible, with the best documentation, and the Power Users may provide you with several recommendations of how to improve your ex…

Also let me suggest some cosmetical changes
your extension is about images, so the word image is unnecessary to use in method names

For example
OutputImagePath --> OutputPath
ImagePath --> OutputPath
These are the setter and getter properties of the output path, so the property name should be the same and not different

Image --> InputPath
BlurImage --> Blur
BlurImageByColumn --> BlurByColumn
Etc
The methods ImgHeight and ImgWidth should better be properties
ImgHeight --> Height
ImgWidth --> Width
There still is a spelling error for
SetBrigthness --> SetBrightness

[Patryk_F]

I also think that the extension needs to be adapted to work in the companion. I mean handling images from assets in the companion.

[jean-marc_Latour]

ok, but i don't know what is the problem with companion...it told me it can't load file in assets, but i don't know why...

[Taifun]

Check the App Inventor sources, how it is done there... for example the image component...
