Concerning image functions- what would be useful?

Mordecai

Right now (and over the past few weeks, seldomly) I am writing an include for use in graphic-editing PHP scripts. It defines some useful but nonincluded functions from the GD library.

What I want to know is what do you all think would be useful things to have?

Here are some of the functions I have defined already:
imagetile() - tile an image onto another image
imagelinedotted() - draw a dotted line
imagezoom() - zoom in on a section of an image
imagegrayscale() - turn an image to its grayscale equivalent
imagecolorize() - colorize an image to a specified color with a percent
imagettftextshadow() - TTF text with a shadow with dynamic pixel offset
imagettftextoutline() - TTF text with an outline of a given width, in pixels
imagettftransparent() - TTF text with an alpha transparency of a given percent
imagettftexture() - TTF text with an image filling
imageopacity() - change the opacity of an image
imagegrid() - draw a grid on the image with specified width and height
imagegriddotted() - a dotted grid

So, what are your thoughts?

How about rotating images and/or text, drawing common shapes, and trimming images?

A working 'colortransparent' so I can finally use my masked images...

GD already has built in image rotation- imagerotate().
As for text, one can supply the angle for TTF text, which is rotation. All the text functions I wrote have the ability to rotate, as well.

Common shapes - I like this idea, but imagepolygon() can pretty much do any shape. I suppose I can refine it by supplying a set of coordinates for a few shapes.

Trimming images - I'm surprised that's not included. This is fairly easy to do, and would be quite useful.

PyroX, what's wrong with colortransparent? I use it all the time. The only thing I don't like is when the color is in use by something else, and that ends up being transparent... I can't really think of a way around this, but I'd certainly like one. 🙂

Thanks for your input, both of you.

Any one else have something to contribute? I could really use some help.

It does not seem to work for me. I have some mostly earth tone images that a map engine I had written was going to use to generate world maps on the fly for an online game. I used hot pink as a mask color, as it would never appear anywhere else.

I would use photoshop's color info to select the appropriate color info and then set color transparent on both the imge to be overlayed and the image being drawn on, and it would work to a very small degree, making the color translucent, but not transparent. And it would not allow any varience whatsoever, so thet for example 255.240.240 would leave 256.240.240 ( not hot pink just an example ). I suppose this is the way it was ment to function, but not leaving most of the color simply translucent.

I've never had it do that... It's always entirely transparent.
Care showing me some code?
