Re: [Imtoolkit-users] Draw line on a image

[Antonio S. <sc...@te...>]

Here it is in Lua:

require"imlua"
require"imlua_process"
require"cdlua"
require"cdluaim"

local crd = im.ImageCreate(2200, 1700, im.RGB, im.BYTE)
im.ProcessRenderConstant(crd, {255, 255, 255})
local canvas = crd:cdCreateCanvas()
canvas:LineStyle(cd.DASHED)
canvas:Line(10, 10, 50, 50)
cd.KillCanvas(canvas)
im.FileImageSave("a.png", "PNG", crd)

Re: [Imtoolkit-users] Draw line on a image

[Milind G. <mil...@gm...>]

Tried this:

local crd = im.ImageCreate(2200, 1700, im.RGB, im.BYTE)
    im.ProcessRenderConstant(crd, {255, 255, 255})
canvas =
cd.CreateCanvas(cd.IMAGERGB,tostring(crd:Width()).."x"..tostring(crd:Height()).."
0x"..tostring(crd[0]):match("imImageChannel%((.-)%)").."
0x"..tostring(crd[1]):match("imImageChannel%((.-)%)").."
0x"..tostring(crd[2]):match("imImageChannel%((.-)%)"))
canvas:LineStyle(cd.DASHED)
canvas:Line(10, 10, 50, 50)
cd.KillCanvas(canvas)
im.FileImageSave("a.png", "PNG", crd)

But did not work just a white image

Thanks for sending the steps. I am struggling to find a lua equivalent. Is

Re: [Imtoolkit-users] Draw line on a image

[Antonio S. <sc...@te...>]

 Hi,

 Using the CD library. You can create a CD_IMAGERGB canvas using the
existing image buffers.

 Here is a sample in C:

imImage* image = *imImageCreate*(width, height, IM_RGB, IM_BYTE);
// Can also call *imImageAddAlpha* if alpha support is wanted
cdCanvas* canvas = cdCreateCanvasf(CD_IMAGERGB, "%dx%d %p %p %p",
width, height,
                                   image->data[0], image->data[1],
image->data[2]);cdCanvasLineStyle(canvas, CD_DASHED);
cdCanvasLine(canvas, 10, 10, 50, 50);
cdKillCanvas(canvas);
*imFileImageSave*(file_name, "PNG", image);*imImageDestroy*(image);

Best,
Scuri

Hi,
       I am combining some images on a bigger images. How can I draw lines
also on that combined image?

Re: [Imtoolkit-users] Convert loaded gif file

The last line ProcessResize was causing lua to crash but using
ProcessResizeNew fixed it.

Re: [Imtoolkit-users] Convert loaded gif file

[Antonio S. <sc...@te...>]

  What kind of crash?

  In which line?

  I recommend using:

newimg = im.ImageCreateBased(image, 500,374, nil, nil)
or
newimg = im.ProcessResizeNew(image,500,374,1)

  Instead of directly using im.RGB.

Best,
Scuri

Re: [Imtoolkit-users] Convert loaded gif file

[Antonio S. <sc...@te...>]

 ok. Then you will need to first convert the loaded image to RGB first.

if (image:ColorSpace() == im.MAP or image:ColorSpace() == im.BINARY) then
  new_image = im.ConvertColorSpaceNew(image, im.RGB, false)
  image:Destroy()
  image = new_image
end

Actually I want to merge it with a jpg image I loaded with  im.ImageCreate(r_w,

How can I achieve that?

Re: [Imtoolkit-users] Convert loaded gif file

[Antonio S. <sc...@te...>]

  The image in the GIF file is not an RGB image. So it loaded a im.MAP
image. That's why the resize failed.

  So there are a few ways to make it work.

-- assume the image is map
r_img = im.ImageCreate(r_w, r_h, im.MAP, im.BYTE)

-- create a new image based on the old one
r_img = im.ImageCreateBased(image, r_w, r_h, nil, nil)

-- let the ResizeNew do it all
r_img = im.ProcessResizeNew(image, r_w, r_h, order)

  But it would be better to user the write interpolation order. im.MAP
images can not be linear interpolated.

order = 1
if (image:ColorSpace() == im.MAP or image:ColorSpace() == im.BINARY) then
  order = 0
end


Best,
Scuri

[Imtoolkit-users] Convert loaded gif file

[Milind G. <mil...@gm...>]

Hi,
        I am loading a gif file using image =
im.FileImageLoadBitmap(fileName) then I want to resize this loaded file so
I tried:
r_img = im.ImageCreate(r_w, r_h, im.RGB, im.BYTE)
im.ProcessResize(image, r_img, 1) -- do bilinear interpolation

But I get this error:
images must have the same data type and color space
stack traceback:
        [C]: in function 'ProcessResize'
        bingo.lua:50: in function 'resizeImage'
        bingo.lua:81: in function 'SavePalettes'
        bingo.lua:103: in main chunk
        [C]: ?

How can I do the appropriate conversion so that the resize works.

Thanks,
Milind

  Hi,

 

  Your Project is configured to build 32 bits applications. You need the 32 bits version of IM, but you are using the 64 bits.

Hello,

 

so I tried m-3.8.2_Win64_vc11_lib.zip following webpage guide. I send build logs from VS12 in two levels of detail for easier reading.

 

Thank you

  So in this case you can use 32 or 64 bits pre-compiled libraries. 

 

 For Visual Studio 2012, you should use the im-3.8.2_Win32_vc11_lib.zip or im-3.8.2_Win64_vc11_lib.zip for static libraries. And im-3.8.2_Win32_dll11_lib.zip or im-3.8.2_Win64_dll11_lib.zip for dynamic libraries. 

 

  Then assuming that you downloaded one the packages above, and configured the project settings according to http://www.tecgraf.puc-riobr/iup/en/ide_guide/msvc8.html but using only the libraries you actually need for your project. 

 

  What is the result? I mean, send the Visual Studio build log attached so maybe I can tell you what’s wrong in the configuration. 

 

Best, 

Scuri

  Certainly is something wrong in your Project settings.

Hello,

 

I’m trying to use IM toolkit in my diploma thesis, but I encountered a problem, when I wanted to link IM with MS VS 2012.

I’m using MS Visual Studio Professional 2012 Version 11.0.61030.00 Update 4. Programming language is purely C

I tried to use almost all IM 3.8.1 and 3.8.2 Windows (both 32bit and 64bit) packages including cygwin versions,

but best what I was able to achieve was error message saying: XY.c is not valid Windows application. But more often

I was experiencing many linking errors like LNK 2001, LNK 2019, LNK 2005 and so on. Of course I used guide from official

webpage (http://www.tecgraf.puc-riobr/iup/en/ide_guide/msvc8html <http://wwwtecgraf.puc-rio.br/iup/en/ide_guide/msvc8.html> ) but to no purpose. Code errors are excluded

because I was trying to compile samples from IM webpages and some very primitive pieces of code. All this leads me

to think that it must be linking error but I’m unable to find solution.

 

Thank you in advance and sorry for my English.

Hello,

 

  I recently was surprised to discover that IM doesn't support writing TGA
files that include an Alpha channel. I wrote a very simple patch for it, and
it seems to be working fine, so I figured I'd share it.
