[Approved] borders for your images and buttons (new feature) (1 Viewer)

[ajp8164]

[ EDIT: I can post a patch to svn 23209 if it makes inserting this into svn easier. I recently updated my workspace to 23209 and had a heck of a time patching GUIImage.cs (I ended up doing it manually - there was just too many changes since my last workspace snapshot).

EDIT 2: I found a bug in my patch that prevents the border from taking part in animations. I have attached a second, incremental change patch the corrects this problem. The second patch must be applied after the original patch - the second patch changes only CachedTexture.cs to incorporate the (global) final transform matrix.]

This patch adds bordering support to image and button control types. With this patch you have the ability to add borders composed of textures that you identify. Each border (around an image or button) is a rectangular shape and each side of the border rectangle is itself a rectangle drawn with the specified border texture. The following attributes are added to image and border control types as specified:

Image control attributes:

border - specifies a comma separated list of border edge thickness for each side of the border. The order of values is left, right, top, bottom. This field accepts either four integer values separated by commas or a single integer value which is then used for all four sides. Examples: <border>10</border> -or- <border>10,10,1,1</border>

border, position - specifies the position of the border relative to the image edges. Valid values are "outside", "inside", "center". The default value is "outside". Example: <border position="center">10</border>

border, textureRepeat - specifies whether the texture used for the border should repeat or stretch inside each of the four rectangles that compose the overall border. The default value is "no". Example: <border textureRepeat="yes">10</border>

border, textureRotate - specifies whether or not the texture used for the border should be rotated for each of the border rectangles. If the texture should rotate then the texture will be rotated 90 deg for the right border rectangle, 180 deg for the bottom, and 270 deg for the left. The default value is "no". Example: <border textureRotate="yes">10</border>

border, texture - specifies the tetxure filename for the border rectangles. A single file is used for all four of the border rectangles. Based on the value of textureRepeat, the entire texture extent is either stretched (scaled up/down) to fill the border rectangles or is scaled (up/down) to fit inside the border rectangle at its native aspect ratio and repeatedly drawn until the border rectangle is filled. The default value is "image_border.png". This texture file must exist in the skin media directory otherwise no border will be drawn. Example: <border texture="my_border.png">10</border>

border, colorKey - specfies the color key for the border texture. The default value is 0xFFFFFFFF. Example: <border colorKey="0x66FFFFFF">10</border>

Button control attributes:

The button control border attributes are identical to those on the image control, however, since the button control manages three images the implementation extends to each of the three images; textureFocus, textureNoFocus, and hover.

Examples:
<textureFocus border="10" position="center" texture="my_border.png">my_focus_texture.png</textureFocus>
<textureNoFocus border="10" position="center" texture="my_border.png">my_no_focus_texture.png</textureNoFocus>
<hover border="10" position="center" texture="my_border.png">my_hover_texture.png</hover>

The implementation alters GUIImage.cs, GUIButtonControl.cs, GUIAnimation.cs, and CachedTexture.cs and is backward compatible (it will not break any existing skins). Application of this patch will change only Core.dll (the GUI library).

I have done a lot of testing to make sure all the algorithms work -- I spent a lot of time on the DrawBorder() method in GUIImage.cs so I hope ya'll like this new feature.

One thing I noticed is that if the texture you specify as the border texture is much bigger than then border rectangles then it may not render very nicely. If this happens simply scale down the texture image to be closer to the border rectangle sizes. The poor rendering appears to be an artifact of MS DirectX implementation (read - there's nothing I can do about it).

I have included a number of images (to get you excited about this patch) including the images I used for the border textures so you can recreate exactly what I have used in testing. The following skin xml produces the attached images. Note the images with the star borders; look at the orientation of the top of the star in the first images vs. the others (example of textureRotate) and look at the position of the star borders in each image with respect to the semi-transparent button image (example of position center,inside,outside).

Has this patch already been committed to current SVN?

Hi.
A big thank you for all your great work, hope it will not be deleted

I notice some strange problems with borders in image control.

Spoiler

<control>
<description>Current Channel Thumb</description>
<type>image</type>
<id>204</id>
<posX>25</posX>
<posY>540</posY>
<width>150</width>
<height>150</height>
<texture flipY="true" diffuse="diffusemirrorwide.png">#TV.View.thumb</texture>
<border texture="border.png" textureRotate="yes">15</border>
<keepaspectratio>yes</keepaspectratio>
<centered>yes</centered>
</control>

And it is what i want to reach and I've done with conventional methods but for logos with different aspect ratio it's not possible. I thing the simple method of stretch in background or in foreground of image could be the best solution. In high screen resolution is every pixel visible and important

I am making patch to fix some issues and to add corner support, but in the mean time...

Two things you need to look at:

1.) Add textureRepeat attribute to your xml as follows.

<border texture="border.png" textureRotate="yes" textureRepeat="yes">15</border>

This attribute specifies that the texture you are using for the border should *not* be stretched inside the (four) rectangles used for each border edge. Tiling the texture to create the border works better than stretching it. Also, textureRepeat only repeats along the long side of the border rectangle as described below (each T is an instance of the border texture proportionally scaled to fit into the specified border width.

+--------------------+
|TTTTTTTTTTTTTTTTTTTT|
+--------------------+

If textureRepeat is not on then the texture should be stretched to fill the rectangle - there is a problem with the calcs with large border textures that cause the shortened border edges you are seeing.

2.) The border image you use needs to be "very well constructed". Create a vertical slice of your desired border that is larger than (or the exact size of) the border you want to draw. If the border texture is smaller than the intended render size then the scaling up will look very bad; if it's too big then the scale-down will look bad too (especially for textures with gradient). Also, make sure that the border texture runs completely to the image edges; this makes the tiling of the border using textureRepeat work as expected. Any white space or other "gap" at the edge of the border texture will not look good when rendered (will look like a dashed-line border). Take a look at the sample border textures I posted in my original post; hopefully that will help too.

Either way, with the posted implementation the corners will not look very good (read, unacceptable). :sorry:

When I post an update to add corners I will also post some sample borders and a psd file to help create new borders and corners. I have posted attached a picture that was rendered using the new code (includes corners). I think there is plenty of flexibility to create all kinds of very nice *scalable* image borders... stay tuned!

and thanks for the encouragement

hi,

is there a way to also use rounded corners ?

Hi Harley -

The attached is not an official patch submission, it is for information only and subject to change.

YES! You can! I have an update to this implementation that both fixes some problems and adds support for defining custom corners for your border. I have not yet posted the patch because I am waiting for the next baseline that incorporate my changes to date. It's a lot of work to resolve patches at the moment... However, I will attach my patch to this post as an "as-is" post. You should be able to resolve all the changes if you are diligent ;-)

In order to implement the corners efficiently I needed to make a change to the fontEngine. It's a simple change and excludes all other scenarios so it shouldn't have any side effects (fontEngine is core to MP's behavior).

To use corners on image borders I have added the following attributes to the border skin tag on GUIImage (which is also propagated to other controls like button).

border, corners - specifies that the border should use corner rendering logic. The default value is false. Example: <border corners="yes">10</border>. Implies the use of a default texture file named image_border_corner.png.

border, cornerRotate - specifies that the border corner should be rotated for each corner. Does not imply that the corner rendering logic should be used. The default value is true. Example: <border corners="yes" cornerRotate="yes">10</border>. Again, implies the use of a default texture file named image_border_corner.png.

Now, this implementation requires that you create the upper left border and that cornerRotate will rotate and position the border image as needed for the other three corners.

Since I created this implementation I have determined that a better implementation would be to have the corners texture be a complete texture representing all four borders and the edges (a packed texture if you will). Doing this would do several things; (1.) avoid having to change the fontEngine and (2.) allow for a more flexible user implementation - e.g. use of a shadowed borders, and (3.) would simplify the skin interface. Making this change will take some time and would also change my base implementation - I will likely be able to look at making the changes some time in the next few weeks. For now, though, this is a good implementation and works well.

Thanks for your interest and comments! Let me know how it goes.

[cul8er]

Hi,

Will this patch "only" make it possible to add rounded corners to images or will it also make the actual image have rounded corners (mask the area outside of the rounded corners with the background image)?

best regards

Maybe a dumb question, but how do I apply a patch file?

 

[pilehave]

Maybe a dumb question, but how do I apply a patch file?

You use TortoiseSVN and right-click the folder where the file that should be patched is (somewhere in the MediaPortal trunk directory).

Then you select "Apply patch..." and browse to the patch. Select files to be patched (should be shown automatically). Then it is applied and you can make your build.
