UI/ImageCTX "IMAGECTX_SaveImage" ?

[largo_winch]

I've tested ImageCTX module (Uses "UIAdv") for loading images. there is a command like


IMAGECTX_LoadImage

but I cannot find in help manual


IMAGECTX_SaveImage ?

this command doesn't exist? How I can save a bitmap/jpg/png/tga image with ImageCTX ?
"Canvas_BitmapSave(APP_ScriptPath & "mandelbrot_canvas.bmp")" doesn't work because I am thinking it's just another library. my example failed because there isn't a command for saving ImageCtx_SaveImage. See picture.

does anybody started with translation of gdiplus headers to thinbasic as include file ? If not I can do that with a little help from some thinbasic profis here ;)

ok, my result is negative after googling:

I found "GdipImageCTX" from jose roca's website and that's a fact: "...but this interface doesn't have any method to save images."

Hi Largo,

yes, you are correct. The control is meant only for displaying images, not their manipulation.

hi petr, what's your tipp for saving bmp files? (canvas, tbgl modus) As I saw in formerly month there was an exercise you have tried to save a tga file with tbgl, but the example wasn't ready so far I can remember. what's your idea for saving image files with ui/canvas modus?

bye, largo

largo,

I do not understand when you say that Canvas_BitmapSave is not working.
Here it is working fine bud, of course, it is meant to save image in BMP file format.
Is this working or not?

Thanks
Eros

thinBasic has a lot of power with very few lines of code :D

For converting image types see the example I posted for you at http://www.thinbasic.com/community/showthread.php?11425-canvas_setpixel-(mandelbrot)&p=85063#post85063
I explained the usage of a function present into an undocumented module called GDIP

Let me know.

Ciao
Eros

PS: Canvas_BitmapSave function is working just fine and is working as it is supposed to work: it saves current canvas into a bitmap file image.

Hi Largo,

as Eros wrote, Canvas_BitmapSave works as documented, in TBGL I use TBGL_SaveScreenshot to do the same for TBGL window/control.
I think the tip Eros has in the referenced thread is very usable.

I will check GDIP this evening, if there is time to save for it. thank you eros and petr. @eros: no, I've said saving modus don't work only for GdipImageCTX (that was my problem, but there isn't any chance to do it because there's no function for it), now I will try GDIP and that's all I want to do. no problem I wait for next big issue of thinbasic.
I am at work and that's a horrible day where nobody knows what's going on here because half of stuff is ill, but I like such moments, because I am fit :) bye, largo

Do not forget that in The Thing (http://www.imdb.com/title/tt0084787/), they were all fit on the beginning... (huuuu).

@petr:

1) how I can convert this line to thinbasic?


' Retrieve the handle of the device context
GRAPHIC GET DC TO hdc


to something like


Canvas_Get DC to hdc ?

I will proof gdiplus power for thinbasic just for fun what's possible. I've collected gdiplus code snippets for translation.

2) thanks petr for movie about "THE THING", don't know if somebody has survived at that ancient monster time but here at work there are special forces with enourmous powers (my prof and his adjudant) they can manage nearly everything with my it knowledge (I am practise guy, they have only ideas!) One hour ago I cut into my finger in office kitchen where's a lot of mess and there were broken vine glasses on coffee table. profs! are stupid for real life! ;)

Hi Largo,

I am not sure how ThinBASIC canvas works internally, I would recommend to post new feature request in Support section (http://www.thinbasic.com/community/project.php?projectid=1).


Petr

[largo_winch]

"new feature request" I have done it, thanks for reply. bye, largo

Not necessary. Feature already present.

Please use thinBasic help that is quite completed.

Check under Canvas control: http://www.thinbasic.com/public/products/thinBasic/help/html/canvas_control.htm
You will find all suppoerted CANVAS_* commands.

In particular CANVAS_GetDC at: http://www.thinbasic.com/public/products/thinBasic/help/html/canvas_getdc.htm

It has not one because it isn't needed. You can get a pointer to the Image object with GdipImageCtx_GetImagePtr and then save the image using this pointer with the GdiPlusSaveImageToBmp, GdiPlusSaveImageToJpeg, GdiPlusSaveImageToGif, GdiPlusSaveImageToTiff or GdiPlusSaveImageToPng functions.
