Imitate Photoshop blend effects like multiply, overlay etc

由 穿精又带淫゛_ 提交于 2020-01-10 22:27:32
问题 I'm making a website with a full page background image. I want to create a background image for a side column that acts like a Photoshop layer with multiply as blend mode. It's just a blue colored surface with the 'behaviour' of a Photoshop multiply layer. It's not possible to merge the overlay and the image since the background can change when the website is opened in another screen ratio/size. There are a lot of solutions on SO, but they only work with multiplying 2 images with a fixed

Z-Index div hover overlay issues with [windows] Webkit (Safari, Opera, etc)

由 China☆狼群 提交于 2020-01-07 07:06:08
问题 Edit: This ONLY occurs on Windows Webkit, does not occur on Macs I am trying to set up a grid with fixed sized cells with a background image. When you hover, the background image and height of cell is changed/increased and overlays the row below it. I tried a few ways to create this idea and came down to that a table with z-index applied to the row would work the best. My issue, as the title says, is that I have this working in IE/FF, but for whatever reason webkit doesn't seem to care about

keep jqueryui overlay in same DOM position

由 余生长醉 提交于 2020-01-06 20:06:15
问题 Is there anyway to keep a jQueryUI overlay in the same DOM position? Take a look at this HTML <div id="parent"> <div id="over" title="title"> Stuff </div> </div> JS: $('#over').dialog({modal: true}); If you inspect it on the DOM, you'll notice that the overlay gets moved to a direct child of document.body Is there any way to keep it in it's starting position? (direct child of div#parent )? 回答1: Not sure why you want this, but something like: http://jsfiddle.net/BGBuc/ should get you started.

How to find overlapping connected components

问题 I have two separate images: the first image only contains the black round objects, while the second image only contains the green round objects. I am trying to make a code that will figure out how much of the green is in the black objects. There are three different scenarios that could happen when overlaying image 1 (image with black objects only) and image 2 (image with green objects only) as shown in the image below. I have tried to extract the pixel indices of the black and green objects
