GBPVRLibrary - Open Source Components

[JavaWiz]

The approach for the WizTools UI elements was to introduce common and well known UI elements to gbpvr development. These elements include: Label, Textbox, List, Button, ButtonList, with methods and properties that are also common, .Enabled, .Visible, .Text, ....

Does this approach match what you are trying to achieve with these common controls?

Attached is the helpfile for WizTools.

Specifically, WizUtilities.WizUiHelper Namespace describes each control and associated methods and properties.

Additionally, not sure if you want to suggest comments in the coding standard, if so, SandCastle can be used to easily create helpfiles like the one attached.

yeah all the controls extend GuiElement, but the only property they have that you have listed is "Visible", a popupmenu control doesnt need a Text property, or a list doesnt really need an enabled field. all gbpvr events (keyboard/mouse) etc get passed to each GuiElement, and it bubbles up until one guielement returns true. so you can have a screen, explorer, menu, menubutton, and it will check if menubutton handled the button, then menu then the explorer etc.

yeah i want as much comments in the code as possible, i havent yet commented a heck of a lot, still working on getting the basics down. but before any ticket is closed, all the comments should be done. and if its not, reopen the ticket.

that would be cool, i have a few open tickets to do

just needs to take an ordinary image and make a reflection that fades out.

Committed. I actually separated it into three functions since a couple of the steps may be useful.

• FadeImage will fade to a specified background color.
  
• GetImageReflection will only produce the reflection of your image. I did this because this can help skin developers control whether or not image reflections get used or not.
  
• ReflectImage will produce a copy of the original with the reflection.
  

Customizations:

• You can specify the height of the reflection as a percentage of the original image.
  
• You can specify whether or not to compress the original image in the reflection.
  
• You can specify the direction of fade on the FadeImage function.
  

Issues:

• Background color must be specified. We may need to coordinate with skin developers on this. I didn't look at the skin files but we may need a simple way to grab a preset background color to match to the skin.
  
• Background color cannot be Color.Transparent. The fade doesn't work when it is. I tried redrawing the completed image and adding the transparency but it didn't work too well. Someone with better knowledge of alpha channels may be able to assist with that.
  

Attached are an original image with various transforms applied. All were using White as a background color and in retrospect, Black would have given a better effect with that image but you will get the idea. The image resizing was done outside of the committed code.

yeah i was hoping for a way to fade out the reflection to a transparent colour. it wont be useful all that much if you need to specify the background colour all the time (since most backgrounds are graphics and not simple colours)

[reven]

just had a quick think about the reflection, one way to do it would be
1. flip the image
2. cut the image to the size you want
3. start from the bottom iterate through each line of the image, set the alpha of each pixel to 255 to 0 (0 being the first line).

this might be a little slow, not sure really, might be alright, not a huge complex operation. and it should produce the fade with a true transparent background regardless of the background colour

[whurlston]

It's definitely worth a shot, I'll try it. It might be a couple of days though. Tomorrow starts the rounds with the extended family for me.

[whurlston]

I think I may be able to use the ColorMatrix to do this. I'll let you know if it works.

i moved the imagining library into the "UtilityLibrary" (which i forgot to commit , it only had a logical string comparer in it before)

[whurlston]

K. I was able to get the reflection/fade working properly. The only caveat is that the more pixels it has to process, the longer it takes. Something like posters are almost instant but when you get into something like backgrounds, it takes a few seconds. I'm not concerned with this as it will probably be used for smaller images most of the time. I'll look into speeding it up later but right now I'll just finish it (only left->right and top->bottom fades are working) and clean it up so I can commit it. I'll try to have it committed tonight.

cool, cheers whurlston, ill have a play with it when its committed (want to use it in the "videos" plugin im doing )
