Out of Memory error

[andrew]

Hello Loïc,
I am have issues working with relatively large tiff and jpg images (15,000 x 10,000) all the images are 8bit grayscale.
I am getting a status 3 Out of Memory, when I call any of the following methods,
SetContrast
SetGammaCorrection
SetSaturation
Most if not all of the Fx methods
Most if not all of the ConvertTo methods

I am currently using v5.1.6, however I have found the same issues with v4.5, with the exception that the ConvertTo methods do seem to work.

I have tried breaking the image into zones and applying the methods to the zone and it changes the images just fine however, then end result I require is a 1bpp tif, which I need the ConvertTo method to achive.

I am under a bit of a deadline with this tools, any help would be apprecated.

Thanks,
Andrew

Hi Andrew,

Unfortunately I can't suggest you anything.
If you have an Out Of memory error it is because the GdPicture object needs to allocate more memory than the system allows it...

Like you said, a way consist to divide this image into smaller images, apply your transformations into smaller images then recompose new one merging extracted images.


Best regards,
