According to my experience so far, maple is stupid in image processing.

Frustrated with its functions.

For example, in plotting functions, only bmp, gif, jpeg is supported

while in image package, only jpeg, tif and bmp are supported.

So we take the intersection, only bmp and jpeg files can be used if i want to use plot and image packages at the same time.

If i want to do image processing on the file generated from the plot, like transparency stuff, it is not achievable!

And it totally doesnot support opacity!!

 

Dear all, Is it possible for maple to do image cropping? The problem goes like this: i have two images. Image A: a image containing a random shape which is enclosed. Image B: is a normal image What i want to do is: Crop Image B using the shape in Image A. which comes to my mind is: Step 1: read a list of pixels representing the shape in IMAGE A. Step 2: set the pixels in IMAGE B which are not equal to the list of pixels to be "transparent" Is it achievable in Maple? Or matlab can do it also? Thanks all.

Dear all, Is it possible to get a contourplot with NO contourlines? For example, I specified the "filledregions=true" in plot options. contourplot(-5*x/(x^2+y^2+1), x = -3 .. 3, y = -3 .. 3, grid = [15, 15], filledregions = true) But i do not want to show the contour lines inbetween... Thanks again for you help.

Hi all,

Wondering if there is a way to change the HUE color range that will be used for listdensity plot.

Currently default setting is to use the full HUE color. But what we need is a shorter range, e.g., only from orange to blue.

Can it be achieved?

Or the PLOT structure has to be used?

 

This is the code i am using now.

Hey,

I am uing cmaple.ext to generate batch of images.

However, i found some of the functions are not the same as i execute from the worksheet from standard maple interface.

 

There are lot of white space around the image...

Is there any way to reduce them?
