Background images are floating on the page according to mouse movement. What i want is that whenever there is an image behind/above the text the color of that specific portion of text get's change similar to given image.
I had tried multiple libraries like Frame-motion, GSAP but I am unable find the solution. If there is kindly let me know.
there are a ton of scaling instructions for GIMP but all of them tell you to scale and save easy peasy. I feel like I'm taking crazy pills.
This is what my save or export generates:
How can I simply export a selection? Shouldn't the GIMP instructions include this detail? Sorry for ranting.
In Gimp (and some other popular image editors) the image you work on is actually made of separate images (a.ka.a layers) held together on a "canvas". The "canvas" gives the size of the final image.
There are three different ways to scale things and you have to use the right one:
The Scale tool : scales the active layer by dragging corners. Doesn't change the size of the canvas. This is probably what you used.
Layer>Scale layer: scales the active layer by providing explicit dimensions. Doesn't change the size of the canvas.
Image>Scale image: scales the whole image contents and the canvas. This is probably what you should have used.
What happened to give you the image above is that you resized the layer using the Scale tool, so you got a tiny image in the corner of the canvas, which didn't change size. The uncovered part of the canvas was displayed as a checkerboard pattern. If you exported to a format that supports transparency such as PNG or GIF the image would have been transparent, but since you exported to JPG which doesn't support transparent images Gimp replaced the transparent part by the default background color.
Everything is well explained on their website. https://www.gimp.org/tutorials/GIMP_Quickies/
I have a video with transparent background in .avi format (Made from Adobe After Effects), but the transparent background appears black in mediaelement. Media Player has no background property also.
What should i use so that this media element plays the file and when placed on an image takes that image as its background. (No i cannot embed that image in the avi file as my image keeps changing).
*If my approach is wrong please let me know.
I'm afraid using the normal wpf media player this can't be done.
The mediaplayer ignores the transparent regions, even with video formats that accept it. From memory, i dont think AVI files support transparent regions. MOV files do.
Having said that, and although it could be a very complicated task, it may be possible to enhance the WPFMediaKit mediaplayer to do what you want.

J Morrill the author of wpfmediakit may be able to let you know if it is possible or not.
I might add that i got around this problem in a project once by using a sequence of .png files that played a short 10 second movie. Of course this is not an ideal solution, but it got me out of a jam
Another workaround is to use color keying - assing a color (or more colors) in your video, which you translate to the transparency by a WPF Effect(BitmapEffect or ShaderEffect).
I'm developing a WinForms c# 3.0 application. Our designer created quite a lot of .ico files containing all the needed art. The choice of .ico was made because quite often, the same image is needed in several places in different dimensions.
Now, it seems .ico files are really annoying to use in visual studio. The only way to use those images seems to be through images list (which aren't supported by all controls).
Compared to other resources, you can't write this :
foo.Image = global::RFQHUB.RFQHUBClient.Properties.Resources.foo; // Cannot implicitly convert type 'System.Drawing.Icon' to 'System.Drawing.Image'
Here are the options I'm considering :
create ImageLists of all possible sizes referencing all my icons in my main window. Link these ImageLists from other windows and find a way to export Image objects from the ImageList when I can't use it directly ; since ImageList contains a Draw() method, this should probably be possible.
convert all the x.ico I've got in several x16.gif ...x48.gif, and use those through resources.
I'd be interested to know if some people have been successfully using .ico resources in a Winform application. In so, how did you set up things ?
ICO isn't quite an obsolete format, but it's close. It's still useful for your application icon, but for almost everything else, it's better to use an ImageList for each size that you need. And it's much faster to populate an ImageList from a bitmap that contains multiple images layed out in a grid.
You also want to use an Alpha channel transparency in your bitmaps to get the best result, so storing them as .PNG files in your resources is the best way to go, since PNG supports an alpha channel. ICO and GIF files support only single bit for transparency - every pixel is either fully opaque or fully transparent. An 8 bit alpha channel for transparency looks much nicer.
If you can send your artist back to the drawing board then you should do so, and have him/her do full anti-aliased images with alpha. If you can't, then I suggest that you write a small program to convert all of your icon files into bitmaps suitable for loading into ImageLists.
Convert the images into PNG. Point. Whoever decided to use .ico files to start with should get talked to in private - the argument holds no ground.
If i have a logo, let's say done as a jpg or even a png. Any suggestion for how I can use that to define a path geometry? It would be really good if any suggestions could be provided for how i can do it in blend.
Thanks
Yes - I just tackled this problem for an LOB application two days ago.
I can't offer advice for Blend (though I've read that it can be done in Expression Designer). However, the best free tool I've found for this is called InkScape (http://www.inkscape.org).
It's opensource, and while it's intended primarily for editing SVG vector-based images, it has two key features that are useful to us WPFers:
It can vectorize (i.e. "trace") raster images like bitmaps and jpegs, albeit not as well as one would hope, and
It can export the vector image as XAML
You'll invariably find that you get better results from loading vector formats (like SVG, EMF, WMF, etc) and saving to XAML, than if you try to convert a bitmap/jpeg... simply because the process of vectorizing a raster image is error prone at best. So if you want to bring a company logo into XAML, try to get hold of the source files used to create the logo (perhaps done in Illustrator?) and import that into InkScape.
If this post is helpful, please be kind and give it a one-up.
Jasema is a terrific tool right for the job.
Also, don't be shy to use Blend - it is somewhat more difficult to use (drawing shapes using pen) but it gets easier pretty fast. Switch on gridlines and optionally snap to them for good results.
What both Jasema and Blend are lacking, is the ability to easily create shapes with a central symmetry (like stars), so I took parts from Jasema and created my own tool (named Radius) that works a bit like a combination of a ruler and compass.
I have a good idea but you're png, bmp, jpg or other non vector file is must be very simple because we need best scan results and only use inkscape.
Step: Drag and drop your file workspace on Inkscape, download free.
Tip: If your image is color white, Top menu item File->Document Properties-> heck Checkerboard Background and if you want uncheck Page border show.
Step: Top menu item Path-> Trace Bitmap-> Mode check what you want property, i usually use color property and if your file is png check Remove Background then click OK, then wait again Ok button is Enable and close window.
Step: Now you have a two layer, top layer vektor file and bottom layer your file. Select vector file and top menu item Edit-> XML Editor-> select svg path and look side column, d name propery in your data path value.
But this method may not always work or may not give the desired results and draw your own shapes with the scape so you can get the path data from the XML editor.
Example, my first tests this like:
and after working on it some more:
I've solved my problem (export an image as XAML) using Microsoft Expression Design 4 (Free Version). I've downloaded from the link
http://www.microsoft.com/en-us/download/confirmation.aspx?id=36180
As input, I had Adobe Ilustrator files.
Adobe Illustrator / CorelDraw is perhaps the best tool out there for these operations that I have used.
Personally, I prefer illustrator for on-screen media. These tracings can be exported into several formats such as EPS, SVG, AI, or even XAML (with this plugin)
Best of Luck !!!!
I have recently been struggling with this myself. I had a set of icons done in data and needed to update them to look nicer.
I tried everything, manually typing them out. drawing in svg, converting svg to xaml.
in the end i found a list of open source icons from google material icons.
I then used this to convert from the svg files to data
https://github.com/BerndK/SvgToXaml
It works well but not for the icons i drew myself.
I decided to place all the icons data i convert into an app i built myself that will give you the data and a preview of the icon. feel free to use and contribute. I will keep updating as much as i can.

Convert your image from png to svg in online converter, then drop file into this site http://inloop.github.io/svg2android/ and you will see pathData of your image like below shown in my image.
