I'm trying to remove all white or transparent pixels from an image, leaving the actual image (cropped). I've tried a few solutions, but none seem to work. Any suggestions or am I going to spend the night writing image cropping code?

View 3 RepliesIn my website, users have the ability to upload images to my website. When the image is uploaded it will automatically have a smaller thumbnail created by my website. The thumbnails are not displaying correctly in my repeater though (and by correctly I mean Im not sure how to display them).
Each image sits inside a square div element which is 145 x 145 pixels. Some of the images are 145 wide with a relative height and some are 145 high with a relative width. When my page is displayed the wider images sit at the bottom of my 145 x 145 div,whereas the higher image sit at the bottom and to the left. I would prefer them to all be centered.
I cant find a way to do this is in CSS becuase the images are retrieved dynamically so I cant assign a height beforehand. Is there a way to add white space to my image during the thumbnail creation process so that all images are 145 x 145 but still maintain the aspect ratio? Or can someone think of a good way to do this with CSS and HTML, OR even with javascript (keeping in mind that my images come inside a repeater bound to data in the db.
If you want to see any of my code or the thumbnail creating class just ask.

I am currently working on an invoice report which may or may not span across multiple pages. I have a header which I have setup to only be displayed on the first page, and a footer which I have setup to only be displayed on the last page. The problem is, the hidden header/footer reserves unwanted whitespace and messes up the report layout (see the screenshot). The black areas represent space that is reserved by the header/footer. There must be a simple way to remove this unwanted space.

I am having problems with rendering differences between a gridview control and a local report .rdlc rendering. The dataset shows different spacing between characters in the dataset visualizer than it does in the gridview. The sql reporting services report is more closely rendering what is shown in the visualizer. The dataset is filled From a DAL and then bound to the gridview and reporting service at runtime. I'm currently using VS2008 and programming in VB.

View 2 RepliesI am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.
